Write two expressions to show w increased by 4. Then, draw models to prove that both expressions represent the same thing.

w + 4 and 4 + w

Step-by-step explanation:

Given phrase,

w is increased by 4,

That is, w + 4

By the commutative property of addition,

The expression would be,

4 + w

For drawing a model that shows w + 4

Take two boxes in which first shows w and second shows 4 and add them,

Similarly, for showing 4 + w, take first box that shows 4 and second box that shows w then add them.

Step-by-step explanation:

w+4 and 4+w both are the same because of the commutative property

Step-by-step explanation:

since it says increased it should be addition so I added w + 4
