About the Mathematics in This Unit

Our class is starting a new mathematics unit about multiplication and division called Understanding Equal Groups. During this unit, students develop an understanding that we use multiplication to combine a number of equal groups and that we use division to split a quantity into equal groups. By the end of Grade 3, it is expected that students will be fluent with multiplication combinations up to 10 × 10.

Throughout the unit, students work toward the following goals:

BENCHMARKS/GOALS EXAMPLES
Demonstrate an understanding of multiplication and division as involving equal groups. Three five-pointed stars.

Here are 3 stars.

Each star has 5 points.

There are 15 points in all.

3 × 5 = 15

Solve multiplication and related division problems using skip counting or known multiplication facts.

Ms. Wilson's class is counting around the class by 4s. What number will the 8th student say?

4, 8, 12, 16, 20, 24, 28, 32

A four by eight grid. Half of the grid is shaded.

4 × 8 = (4 × 4) 1 (4 × 4)

4 × 8 = 16 + 16

4 × 8 = 32

Interpret and use multiplication and division notation.

There are 35 flowers. Gina wants to put them in bouquets of 5 flowers each. She can make 7 bouquets.

35 ÷ 5 = 7

BENCHMARKS/GOALS EXAMPLES
