Objective

By the end of this lesson, you will be able to apply arithmetic skills to solve problems related to armies and understand basic concepts of addition and subtraction in a fun and engaging way.

Materials and Prep

Materials: - Paper - Pencil - Toy soldiers or army figures

Preparation: None

Activities

1. Army Addition: Use the toy soldiers to create addition problems. For example, "If there are 3 soldiers on one side and 2 on the other, how many soldiers are there in total?"

2. Subtraction Strategy: Arrange the toy soldiers in rows and practice subtraction by removing soldiers from the formation. For example, "If there are 5 soldiers in a row and 2 leave, how many soldiers are left?"

Second Grade Talking Points

• "In the army, we need to know how many soldiers are in different groups and how many are left after some leave."
• "We can use addition to find the total number of soldiers in different groups and subtraction to find out how many are left after some leave."
• "Let's have fun practicing addition and subtraction with our toy soldiers and see how it relates to the army!"
