About this worksheet

What students practice

Students use turn-around facts to show that changing the order of addends keeps the sum the same.
Students group two addends that make ten before adding the third number.
Students decide whether two addition facts have the same sum.

How to use

Let students build the first few towers with linking cubes, then flip or regroup the cubes to see that the total does not change. Have them finish the rest on their own.
