Using the Distributive Property

A while ago we posted about how we are learning about the distributive and commutative properties in multiplication. We had a lot of fun learning about the properties, but the reason we learn about the properties of multiplication is so we can use them to help us understand math and solve problems.

We have been showing the distributive property in lots of ways. 

One way we showed the distributive property is by making arrays, like this:

Another way we showed the distributive property is the way we usually think of when we think of this property, an equation:  

8 x 7 = (4 x 7) + x 7)

The distributive property helps us with our number sense, because we when we break numbers apart it helps us understand how numbers work.

We made some videos showing our thinking as we used the distributive property to solve math problems. We used the apps Doceri and Educreations to make the videos.

We will continue representing the distributive property in different ways as we learn more about multiplication. Breaking numbers apart is an important skill and will help us solve more difficult problems. We will also continue to work on explaining our thinking as being able to explain what we are doing shows understanding.

Do you use the distributive property when you solve multiplication problems? Or do you use a different strategy? We would love to hear about it in the comment section below.
