- Army-themed worksheets (can be created by the teacher)
No prior knowledge is required for this lesson.
Activities
- Introduction to Army Arithmetic: Start by discussing the Army and its importance. Talk about how soldiers use math in their daily tasks, such as counting supplies, tracking distances, and calculating time.
- Counting Soldiers: Create a worksheet with pictures of soldiers and numbers next to them. Ask the student to count the soldiers and write the corresponding numbers.
- Adding Army Supplies: Create another worksheet with pictures of army supplies and addition problems. For example, show a picture of 3 helmets and 2 backpacks, and ask the student to add them together and write the answer.
- Subtracting Soldiers: Create a worksheet with pictures of soldiers and subtraction problems. For instance, show a picture of 7 soldiers and ask the student to subtract 3 soldiers and write the answer.
- Time for Duty: Discuss the concept of time and how it is crucial in the Army. Ask the student to solve simple time-related problems, such as calculating how many hours soldiers sleep or how long it takes to march a certain distance.
