1. What number sentences can you write that equal 30?

2.  Think of different kinds of equations.  You will want to reach 30 in several different ways.  Use at least two different operations to create collections of number sentences to equal 30.


Organize the equations that are alike in some way and under each list explain what makes those equations alike.



1 X 30 = 30
29 + 1 = 30
32 -   2 = 30
2 X 50 = 30
28 + 2 = 30
40 - 10 = 30
3 X 10 = 30
27 + 3 = 30
37 -   7 = 30

These are just some of the possibilities.  You get the idea.
