Multi-Digit Operations

In this unit students

•  cement understanding of the standard algorithm for multiplication of multi-digit whole numbers;
•  solve division problems with whole number quotients;
•  add, subtract, multiply, and divide decimals to hundredths;
•  write and interpret numerical expressions.

Students use the standard algorithm for multiplying multi-digit whole numbers, which is woven into topics, lessons, and practice throughout the year in order for students to develop fluency. Students work with division, both whole numbers and decimals (to hundredths), using equations, illustrations, and area models to explain their thinking. Addition and subtraction work are being done in the context of decimals.
