Making Addition Sentences True

Introduce scholars to the commutative and additive identity properties of addition with two sets of practice problems. First, they fill in the missing addend by choosing from a group of three possible answers. These six addition equations display both properties. In the next set, learners solve 15 similar problems without answer options, again practicing both operations. Mathematicians will see one, two, and three-digit numbers in this exercise, and can use the example problems as guidance.
