zero property - any number times 0 is always 0

7 x 0 = 0 or 233,987 x 0 = 0

identity property - any number times 1 is always that number

7 x 1 = 7 or 233,987 x 1 = 233,987

commutative property - two numbers multiplied in any order give the same product

4 x 6 = 24 and 6 x 4 = 24

distributive property - break apart a problem into two simpler problems

4 x 6 = (2 x 6) + (2 x 6)

2 Daily Common Core Review

Activity: Other — Warm Up

A restaurant cuts its large pizza pies into 8 equal pieces. How many total pieces of pizza are in 9 pies?

3 Guided Practice

Activity: Conversing

Focus Question:

How can you break apart facts?

Turn and Talk

So we all know how to multiply facts with 0,1,2 and 5. We are going to combine these facts wit other facts.

Suppose we know that 2 x 4 = 8

Do you need to learn something new to learn 4 x 2 = 8?


What property is being shown here?

4 Student Practice

Activity: Creating

Create two 4 x 6 grids on grid paper. Write a multiplication expression for the first grid. Color the second grid with 2 colors to show 2 smaller grids. Make each smaller grid represent a multiplication fact that you already know. Write the multiplication expression for each of these grids.


Work with a partner. Use the grid paper to find 7 x 7 by breaking it apart into two facts.

Try 6 x 8 next.


Turn and talk to your partner about what the distributive property is. How or why can this be helpful?
