Illustrative Mathematics Introduces IM Certification Program to Meet Demand for High-Quality, Job-Embedded Professional Development for Teachers

Tucson, AZ – June 14, 2018 — Illustrative Mathematics (IM) today announced the launch of its IM Certification™ program, which trains qualified mathematics educators to deliver scalable, high-quality, expert-developed professional learning experiences that support adoptions of the acclaimed Illustrative Mathematics curriculum.

IM Certified Facilitators lead school and district PD on IM’s behalf, supporting districts that have adopted the organization’s acclaimed middle school curriculum, Illustrative Mathematics 6–8 Math.

“Our curricula are research-based, expert-authored, standards-aligned, and meet stringent quality benchmarks,” says Illustrative Mathematics CEO, Lisa O’Masta. “Our IM Certification program is held to the same high standards as our curriculum, and it reflects the latest research on best practices for supporting professional learning for mathematics educators.”

In response to increased district demand for IM-led professional development, the nonprofit has launched a competitive certification program to discover and train future facilitators. The first cohort of facilitators-in-training will be announced in July 2018.

“Teachers using IM’s high-quality instructional materials need structured, long-term support for improving instruction and internalizing the protocols they need to continue their learning, independently and in collaboration with their peers,” says Katie Martin, lead secondary math teacher for New Hanover County Schools in Wilmington, North Carolina. “We consider a facilitator’s 'IM Certified' stamp shorthand for quality and expertise, both in mathematics and in delivering to teachers and coaches the very best professional learning experiences.”

“Switching to problem-based instruction requires a shift in teaching practice for many teachers. Even when schools adopt a coherent, well-aligned curriculum, they are often missing job-embedded professional learning supports,” says IM founder Dr. Bill McCallum. “To have an impact mathematics teaching and learning at scale and to close the achievement gap, teachers need access to both high-quality curriculum materials and complementary professional learning. We are excited to welcome into the IM fold this cohort of talented educators who will deepen the impact of our curriculum on students and teachers.”

Illustrative Mathematics Receives Funding to Expand Its Expert-Created Curriculum and Professional Services to Grades PreK–5

Building upon the highly acclaimed Illustrative Mathematics 6–8 Math Curriculum, the nonprofit will develop the curriculum framework and blueprints for PreK–5 classrooms, along with unit modules and professional learning for Kindergarten.

Tucson, AZ – April 24, 2018 — Illustrative Mathematics (IM) today announced it has received philanthropic funding from the W.K. Kellogg Foundation (WKKF) to continue its work building freely available mathematics curriculum for PreK–12 classrooms.

In service of its larger plan to release a full PreK–5 program as an Open Educational Resource (OER), IM will use the WKKF grant to construct a PreK–5 curriculum framework, Kindergarten curriculum modules, and professional learning supports. All materials will be based on early childhood learning research, standards for mathematics progressions, and best practices in supporting professional learning for elementary educators.

While many elementary curriculum programs are available to districts, educators often focus their limited resources on grades 3–5, when testing generally begins. “Research tells us that what students know when they enter Kindergarten is a predictor of middle school achievement,” says Illustrative Mathematics founder and president Dr. Bill McCallum. “To improve elementary mathematics teaching and learning, we have to establish a strong foundation right from the start—teachers need access to high-quality, coherent, balanced curriculum, as well as ongoing and embedded professional learning, so that they can support students at the beginning of their mathematical journey.”

IM released its first OER core program, Illustrative Mathematics 6–8 Math, in 2017, after a year-long, 175-teacher beta effort to refine the materials. The problem-based curriculum sparks discussion, perseverance, and enjoyment of mathematics. Students learn by doing, solving problems in mathematical and real-world contexts, and constructing arguments using precise language.

The IM 6–8 curriculum received the highest rating among middle school math programs on EdReports, the independent nonprofit conducting in-depth materials evaluations based on the alignment of the curriculum to standards, in addition to indicators of content quality and usability.

With the tremendous interest and excitement from IM’s middle school program, requests from educators to see IM expand to elementary and high school grades have been overwhelming. IM sees its efforts to author affordable, high-quality mathematics curricula as only the first step toward closing the achievement gap and creating educational equity. “To successfully implement quality materials, educators need professional development that elevates their practice and supports the shift toward a classroom driven by student discourse,” says Lisa O’Masta, CEO of IM. “We release our curricula for free as OER so districts can afford both quality curriculum and quality professional learning without sacrificing one or the other.”

“We believe all children should have an equal opportunity to live a full life with high-quality early childhood experiences,” says WKKF program officer Renee Blahuta. “Pre-Kindergarten and Kindergarten help set the foundation for success in mathematics throughout life, so elementary educators need equitable access to exceptional materials that make math accessible to all learners. Based on their experience with middle school mathematics and their exceptional reputation among educators, IM is uniquely qualified to spearhead work on a coherent OER PreK–5 curriculum that engages children and supports thriving communities.”

In addition to beginning development on an elementary curriculum, IM is expected to launch an OER high school curriculum in 2019. Looking forward, IM plans to build on the results of these efforts to develop a complete, coherent, and freely available PreK–12 curriculum, supported by scalable and high-quality professional learning opportunities.

“We’re thankful to WKKF for supporting our efforts to build a comprehensive program that sparks learners’ understanding and enjoyment of mathematics,” adds McCallum.

Illustrative Mathematics 6–8 Math Meets Expectations in all EdReports Gateways—
A first among middle school math curricula

After extensive review from educators nationwide, Illustrative Mathematics 6–8 Math meets expectations in all 3 Gateways of EdReports: Focus & Coherence, Rigor & Mathematical Practice, and Usability.

Tuscon, AZ – January 24, 2018 — Illustrative Mathematics 6–8 Math, the first curriculum from nonprofit publisher Open Up Resources, is the only middle school math series to meet expectations across all three Gateways in EdReports, an independent nonprofit that reviews K–12 curricula for standards alignment and quality.

A problem-based curriculum that develops students’ mathematical reasoning skills and fosters discussion-filled classrooms, Illustrative Mathematics 6–8 Math was developed through a partnership between Open Up Resources and Illustrative Mathematics, the nonprofit founded by lead standards author Bill McCallum.

Under EdReports’ extensive review process, a diverse group of highly trained educators met weekly to review and score the curriculum against detailed criteria for three categories:

  • Standards Alignment Focus & Coherence: Are the instructional materials aligned to the standards?
  • Standards Alignment Rigor & Mathematical Practices: Are all standards present and treated with the appropriate depth and quality required to support students?
  • Usability: On measures of classroom utility, how teacher- and student-friendly are the materials and how do they foster student growth?

After an extensive examination, the educator review team scored the curriculum a perfect 14/14 for Focus & Coherence, a perfect 18/18 for Rigor & Mathematical Practices, and a near-perfect 37/38 for Usability in each grade level.

During its curriculum development process, Open Up Resources reviews each program against expert-developed instruments, including the EQuIP and IMET rubrics, as well as proprietary standards for English language learner supports. Curriculum authors integrate this feedback, as well as feedback from teachers using the curriculum in beta release, as they refine and finalize the materials.

Said lead author Bill McCallum of Illustrative Mathematics, "Our curriculum writing team of mathematicians and educators worked hard to produce a curriculum that follows a coherent progression, focuses on important mathematics, and engages students in sharing their reasoning. I couldn’t be more proud of the work they have done."

As school districts become increasingly dissatisfied with the lack of standards-aligned, high-quality offerings from the major publishers, EdReports offers a way for districts to quickly gauge curriculum quality against important metrics before making a determination on materials adoption.

Not only is Illustrative Mathematics 6–8 Math the only middle school math curriculum to score top marks across the board, the curriculum has been published as an Open Educational Resource (OER), which means it is available to all districts at no cost. Even after investing in the professional development or print materials that accompany the curriculum, districts that adopt Illustrative Mathematics 6–8 Math still pay far less than they would for traditional textbooks—often the savings can exceed 80 percent.

Illustrative Mathematics 6–8 Math, which was made available as an OER just before the 2017–18 school year, has been adopted by hundreds of districts to date, including Sunnyside Unified School District (AZ), Buncombe County Schools (NC), Evergreen Public Schools (WA), and Tumwater School District (WA).

The curriculum was fine-tuned over the course of a yearlong, 175-teacher beta release. A survey of the teachers who used Illustrative Mathematics 6–8 Math in its beta release showed that 90 percent found the curriculum highly effective or effective. Another 90 percent said that they would either recommend—or had already recommended—that their peers use the curriculum. "This curriculum has been a game-changer for us, because it fosters active learning by our students," said David Parascand, Math Specialist in Tumwater School District (WA), a district that participated in the 2016–17 beta release of the curriculum before adopting it. "Students discuss the math they’re learning every day, and because their thinking is really visible, teachers can give every student exactly the support they need. “In addition, the curriculum authors were extremely receptive to our team’s feedback during the beta release. This appreciation of the needs of teachers likely translated into the high Usability marks for in this EdReports review," said Parascand.

Illustrative Mathematics to Develop Openly Licensed High School Math Curriculum in Partnership with Open Up Resources

Following the successful release of their middle school math curriculum, Illustrative Mathematics begins development of a comprehensive high school math curriculum that will also be freely available to schools.

Tucson, AZ – August 29, 2017 — Illustrative Mathematics is pleased to announce they will be partnering again with Open Up Resources to develop a comprehensive high school math curriculum that will provide educators affordable access to standards-aligned content, teaching resources, and professional learning services that are not currently found in other curricula on the market. The curriculum is slated to be piloted during the 2018–19 school year and published as an Open Educational Resource (OER) for 2019–20 adoption by schools and districts. The high school math curriculum comes on the heels of the development of the highly anticipated Illustrative Mathematics 6–8 Math which is being evaluated by hundreds of districts.

“We are excited to continue our work with Open Up Resources to fill the quality gap in the K–12 mathematics curriculum market,” said acclaimed mathematician and Illustrative Mathematics founder and president, Dr. William McCallum. “There is a great need for high-quality standards-aligned curriculum across the grades. Our grades 6–8 mathematics curriculum addresses the focus, coherence, and rigor called for by the standards, so lacking in many curricula for grades 6–8. We now plan to do the same for high school. We will start by researching specific needs in high school classrooms for improved student outcomes, and will design the new high school mathematics curriculum in line with that research.”

The comprehensive high school curriculum will cover Algebra 1, Geometry, and Algebra 2 and will flow coherently from the middle school program. Based on sound mathematical progressions, the curriculum will develop students’ mathematical thinking skills through questioning, discussion, and real-world contexts and connections. The curriculum will also leverage the mathematical language routines developed by Stanford University’s UL-SCALE to support English language learners, and will include built-in differentiation supports for students with disabilities and accelerated students.

According to Dr. McCallum, “input from educators will be vital to the development of the high school curriculum. While we already know that existing math curricula aren’t meeting the needs of today’s educators, we want to make sure we address the specific gaps educators face. From the construct of the lessons to the teacher materials, we will ensure that the new curriculum provides educators with precisely what they need to develop students into mathematical thinkers.”

As with Illustrative Mathematics 6–8 Math, a range of professional learning services will be available from Illustrative Mathematics to introduce teachers to the design of the materials, built-in routines, and resources for differentiating instruction. Ongoing in-person and virtual support will also be available should questions arise as teachers implement the program in their classrooms.

I am proud of the finely crafted work of our team of teachers and mathematicians.”

“Every student deserves access to excellent curriculum, no matter the resources of their school district,” says Larry Singer, Open Up Resources CEO. “Today’s open release of Illustrative Mathematics 6–8 Math sets the standard for our work, as we make freely available a core basil program of truly exceptional quality and support districts across the country with its implementation.”

During the 2016–17 school year, numerous districts nationwide helped fine-tune the curriculum as part of a yearlong pilot. Daily teacher feedback was used by the Illustrative Mathematics authoring team in the refinement of the materials.

The pilot release districts included: Sunnyside Unified School District (AZ), Buncombe County Schools (NC), Vancouver Public Schools (WA), Evergreen Public Schools (WA), Tumwater School District (WA), and Galt Joint Union Elementary School District (CA). All of these districts are continuing to use the curriculum, and most are adopting district-wide.

“We adopted the Illustrative Mathematics curriculum district-wide because we saw huge increases in student engagement with the materials,” says Corrine Williams, Mathematics Specialist at Evergreen Public Schools. “Students were constantly talking about math, using precise language, and constructing mathematically sound arguments. The curriculum facilitates productive struggle for our learners, and teachers have been excited to shift their instruction from being the ‘sage on the stage’ to the ‘guide on the side.’”

“This is the complete, aligned, big-picture-driven curriculum that we have been seeking for many years, says Stefanie Buckner, Mathematics Curriculum Specialist for Buncombe County Schools. “There are products on the market aligned to content or practice, but Illustrative Mathematics 6–8 Math is truly the first that aligns in equal intensity to both. We are excited to move to a district-wide adoption in all three grades this year.”

A survey of the teachers who used the curriculum in its beta release showed that 90 percent found the curriculum highly effective or effective, and another 90 percent said that they would either recommend—or already had recommended—that their peers use the program.

The math curriculum is expected to give districts an 80 percent overall savings versus the cost of adopting materials from traditional publishers. Districts need only invest in implementation services, such as printing and professional development, which Open Up Resources and Illustrative Mathematics provide.

Mad River Local School District Improves Mathematics Instruction with Professional Learning Support from the Non-Profit Illustrative Mathematics

Modeling and coaching help elementary teachers deepen their understanding of the Common Core State Standards for Mathematics and how to implement the standards using GO Math! *

Phoenix, AZ – May 24, 2017 – Elementary teachers throughout the Mad River Local School District near Dayton, OH, are entering their classrooms with renewed confidence in and enthusiasm for teaching math. Partnering with Illustrative Mathematics, a non-profit dedicated to providing guidance to states, districts, curriculum writers, and assessment writers to help improve mathematics education, Mad River’s teachers are now empowered to deliver focused, coherent, rigorous mathematical practices in their classrooms using the Houghton Mifflin Harcourt curriculum, GO Math! The foundation of the district’s success was a one-day professional learning workshop and ongoing coaching from the district’s math coaches.

“During our first year with the Common Core State Standards (CCSS), we quickly realized that in order to provide more effective guidance to teachers in reshaping their classroom practice to meet the standards, our coaching team needed to deepen their own understanding of the standards and their impact on instruction,” shared Mad River Instructional Coach, Amy Holbrook. The district was using K-5 Guidance Documents from Student Achievement Partners to align GO Math! to CCSS, but teachers were craving additional information and direction. The Mad River team was introduced to Illustrative Mathematics by Student Achievement Partners as an organization that could help provide further support in the comprehension and implementation of CCSS using GO Math!

Illustrative Mathematics’ professional learning service team designed a one-day workshop to help Mad River coaches and teachers better understand the standards. Participants learned to:

  • Interpret the guidance documents aligning GO Math! with CCSS.
  • Identify extraneous content within GO Math! based on the standards.
  • Supplement gaps with high-quality, freely available resources through Illustrative Mathematics, LearnZillion, and Engage NY.

Additionally, the Illustrative Mathematics certified facilitator modeled the use of the guidance documents with fraction progressions so that educators could experience what they’d learned in action.

“Our Illustrative Mathematics facilitator dramatically grew our knowledge base and has started to reframe our understanding of the work ahead and better ways to meet the needs of teachers and students,” commented Ms. Holbrook. Following the Illustrative Mathematics workshop, district math coaches worked collaboratively with classroom teachers to develop an action plan using the progression documents. The plan includes implementing Illustrative Mathematics free tasks in the classroom and working with teachers to encourage the consistent use of the new instructional practices that were modeled in the workshop and by coaches.

“Teachers are eager to learn and are looking for ways to enhance their instructional practices so that their students can be successful with the standards. Mad River recognized the need to support teachers as they strive to meet standards and improve students’ learning experiences,” said Lisa O’Masta, CEO of Illustrative Mathematics. “We are honored to have the opportunity to work with the exceptional educators in the district.”

Prior to joining Illustrative Mathematics full time in 2016, Dr. Umland was on the faculty of the Mathematics and Statistics Department at the University of New Mexico. While there, she made significant improvements in the mathematics courses for both elementary and secondary pre-service teachers, adding rigor as well as more-relevant material. In 2011, her support of the national K-12 mathematics community in the transition to the Common Core State Standards in Mathematics (CCSS-M) led to her to collaborate with William McCallum of the University of Arizona, the leader of the CCSS-M writing team, to launch Illustrative Mathematics, a nonprofit organization created by mathematicians, mathematics educators, and teachers, that illustrates how CCSS-M can be effectively implemented.

“When I shared my vision for Illustrative Mathematics with Kristin back in 2010, I discovered that she was already thinking along the same lines about a community to support CCSS-M implementation,” said Dr. McCallum. “Kristin’s ability to strike the balance between mathematical integrity and the needs of students and teachers is unparalleled. Her work for Illustrative Mathematics has been both foundational and transformative. We would not be where we are today without her.” Today, the Illustrative Mathematics website receives an average of one million visitors viewing tasks per month.

As Vice President for Content Development, Dr. Umland has been instrumental in overseeing the development of more than 1,200 highly vetted tasks illustrating CCSS-M by a group of 100 editors and 550 reviewers. She is also the lead author of Open Up Resources Middle School Curriculum authored by Illustrative Mathematics, an Open Educational Resource math curriculum that will be released in July. Throughout her career, Dr. Umland has contributed deep mathematical knowledge and immeasurable support to K-12 educators as they work to prepare students for academic and college and career success, making her one of the outstanding mathematics educators working in the nation today.

Dr. Cathy Kessel Receives the Louise Hay Award from the Association for Women in Mathematics for Contributions in Mathematics Education

Phoenix, AZ – April 3, 2017 – Illustrative Mathematics is proud to announce that Senior Editor Cathy Kessel has received the Twenty-Seventh Annual Louise Hay Award from the Association for Women in Mathematics (AWM). Established in 1991 and presented annually, the award recognizes women who have made outstanding contributions in mathematics education.

Cathy Kessel earned her Ph.D. in mathematics, specializing in mathematical logic, from the University of Colorado, Boulder and has taught mathematics at various institutions of higher education throughout the U.S. During the 1990s, she made the shift from being a mathematician to learning about research in mathematics education, auditing courses at the University of California at Berkeley, and observing and analyzing mathematics teaching and learning in the U.S. and Australia. These activities led to many publications with several education researcher co-authors, and to further work in mathematics education.

A standards, curriculum, or assessment document is often written by a group of writers from different backgrounds—mathematicians, mathematics education researchers, teachers, and other educators. In working with such groups of writers, Dr. Kessel has displayed the ability to edit what mathematicians write, making it readable by educators and the general public, and to edit what educators write, making it readable by mathematicians. Her talents have shaped discussions of mathematics education in the U.S., with works including the Progressions for the Common Core State Standards and The Mathematical Education of Teachers as well as descriptions of mathematics education in East Asia, such as Knowing and Teaching Elementary Mathematics: Teachers’ Understanding of Fundamental Mathematics in China and the United States, Learning Across Boundaries: U.S.–Japan Collaboration in Mathematics, Science and Technology Education, and Mathematics Curriculum, Teacher Professionalism, and Supporting Policies in Korea and the United States.

“For Cathy, mathematics is more than a career,” said Dr. William McCallum, Founder and President of Illustrative Mathematics. “She has dedicated years to making improvements in the field of mathematics education, and her impressive credentials prove her impact. We are honored to have an individual at Illustrative Mathematics who is as knowledgeable, versatile, and passionate as Cathy is. It’s rare to find a mathematics educator who is as equally talented a mathematician as a writer and editor. The field of mathematics should feel as honored to have her as a member of their community. This award is testament to that.”

Upon accepting the award, Dr. Kessel thanked her teachers and mentors. “Receiving this honor makes me very conscious of how many people have helped to improve my scholarship, writing, and editing, and deepen my knowledge of mathematics,” she said. Read Dr. Kessel’s full response, here.

As a Senior Editor at Illustrative Mathematics, Dr. Kessel serves as the lead copy editor for the middle school mathematics curriculum, providing feedback to writers on style and content.
