Adding and Breaking Apart Numbers

The video tutorial explains how to break apart ones to simplify addition. It provides examples using numbers like 29 + 3, 36 + 9, 17 + 5, and 18 + 6, demonstrating how to make tens for easier calculation. The tutorial also covers using 10 frames for visualization and applies these skills to solve word problems. The lesson concludes with a preview of the next topic on using compensation to make tens.

What is the main purpose of breaking apart ones in addition?

• To make division easier

• To make addition easier
