Today's Lesson

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

Addition means putting groups together to find the total. When we see 3 + 2, we start with 3 objects and add 2 more. We can count them all to find the answer: 1, 2, 3... then 4, 5. So 3 + 2 = 5. The "+" symbol means "plus" or "add," and the "=" symbol means "equals" or "the same as."

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.
