Today's Lesson

Today we will learn how to solve subtraction word problems. Math helps us solve problems and understand the world around us.

Subtraction means taking away from a group to find how many are left. When we see 5 - 2, we start with 5 objects and take away 2. We can count what's left: 3 objects remain. So 5 - 2 = 3. The "-" symbol means "minus" or "subtract." Subtraction is the opposite of addition!

Let's break this down step by step so it's easy to understand. Follow along with the examples, and don't worry if it takes some practice to get the hang of it!

Remember: Making mistakes is part of learning. If something is tricky, try again, look at the examples, or ask for help.
