Unit: 3.8

Putting it All Together

In this unit students

•  solve multi-step problems with the four operations on whole numbers;
•  achieve fluency with multiplication and division within 100.

This is a culminating unit for all of the important mathematical work that students have been doing throughout the year. Here they bring together all of the things they have learned in earlier units, and demonstrate and capitalize on their fluent computational skills by solving multi-step word problems using all four operations. They solve problems involving addition and subtraction of time intervals in minutes, liquid volumes and mass, and perimeters of polygons.
