Addition with Packed Blocks - Without Regrouping

Practicing addition with packed blocks is extremely valuable for students, because it helps them see how the traditional algorithm works and helps them build confidence in executing the algorithm. The following example does not have regrouping. Students must be comfortable with addition problems without regrouping and with regrouping.

	Let’s start with the problem 32 + 13. The first step is to build both numbers with packed blocks.
	Next, we must join the two sets of blocks and organize them.
	The blocks are immediately organized. We have the answer, 45.
