Multiplication! Multiplication! Multiplication!

We are learning and loving multiplication! 
Multiplication is repeated addition. 

4 + 4 + 4 = 12

3 groups of 4 balloons = 12 balloons
3 and 4 are factors
12 is the product

We've done a plethora of activities to clarify the properties of multiplication and memorize the facts! We have been attacking multiplication in a multitude of ways!

Making Arrays and Applying the Distributive Property of Multiplication 

The Distributive Property states that multiplying a sum by a number is the same as multiplying each addend by the number and then adding the products

6 x 7

We've even been writing about the Distributive Property of Multiplication over on our 365 Blog. 

Aaron's 324 x 5 example:

Keya's 7 x 8 example:

Students have photographed arrays to share on our class 365 blog

In the comment section, leave an equation for one of the following photos! Challenge, can you then apply commutative property or distributive property to your equation? Try to take your comment to a higher level! Here we go!

1. Mrs. Yollis' pan array 

 2.  Kostaki's picture array

3. Kostaki's bead array

4. Keya's pumpkin seed array

5. Ari's shoe array

6. Kate's pencil array 

7. Abigail's chalk array  

8. Keya's tile array

9. Lily's crayon array

Advanced: This array uses 3 factors and a set of parenthesis. Good luck!

10. Mrs. Yollis' cup cakes

Again, in the comment section, leave an equation for one of these photos! Challenge, can you then apply commutative property or distributive property to your equation? Try to take your comment to a higher level!

What is your favorite multiplication equation?

Which math fact is the most difficult for you?

  1. Dear Mrs. Yollis and class,

    My favorite multiplication equation from these pictures is 6 x 4, which is the chalk array. I like this array because the chalks are lined up nicely. For 6 x 4 the factors are 6 and 4. The product is 24.

    This equation is not in the pictures but, my favorite equation is 9 x 5. The factors are 9 and 5. The product is 45. I liked how you taught us how to do the 9 strategy in class. For this equation, you would bend the your thumb on your first hand.

    Do you like the 9 strategy? If you do, which fact do you like in it?
