About the Mathematics in This Unit

Dear Family,

Our class is starting a new mathematics unit about multiplication and division called How Many Packages and Groups?. In this unit, students build on the work they did in Unit 3. Students solve multiplication and division problems with larger numbers and share a variety of solution strategies.

Throughout the unit, students work toward these goals:

Benchmarks/Goals Examples
Multiply two 2-digit numbers and up to a 4-digit number by a 1-digit number.

The Sunshine Fruit Company sells apples in boxes that hold 28 apples. Sam Brown ordered 32 boxes for his grocery store. How many apples does Mr. Brown have to sell?
