Basic Addition and Problem Solving

In this lesson, the teacher introduces Module 4 Lesson 15, focusing on addition. The lesson begins with a simple example using apples to demonstrate basic addition. The teacher then explores adding groups of tens, showing how simple number sentences can solve larger problems. Using sheep as another example, the teacher illustrates addition with tens. The lesson concludes with student practice problems, reinforcing the learning goal of using simple number sentences to solve larger ones.
