About the Mathematics in This Unit

Our class is starting a new unit about multiplication and division called Cube Patterns, Arrays, and Multiples of 10. During this unit, students build on the work they did in Unit 1. Students identify and analyze arithmetic patterns to examine the relationship between multiplication and division, solve multiplication and division problems, consider what it means to multiply a single-digit number by a multiple of 10, and solve multi-step problems. They also learn the remaining multiplication facts.

Throughout the unit, students work toward these goals:

Benchmarks Examples
Represent and explain the relationship between multiplication and division. An equation and four rows of boxes. A second equation and a row of boxes. 
Solve multiplication and division word problems and write equations to represent problems.

There are 45 students from Grade 3 at the Ernest School who are going on a field trip. There are 9 chaperones. How many students will go with each chaperone?

45 ÷ 9 = _______________

Solve division problems (2-digit number divided by single-digit number).

42 ÷ 6 = _______________

6 × 6 = 36

6 × 1 = 6

36 + 6 = 42

6 + 1 = 7
