Basic Arithmetic Operations and Word Problems

This lesson from Saxon Course 2, Lesson 11, covers problems about combining and separating. It includes examples such as calculating the distance Mr. Chin drove, determining the number of scouts in a troop, finding out how many muffins Tim gave away, and figuring out the initial number of boxes Sharon had. The lesson emphasizes using addition and subtraction to solve these problems.
