Today's Lesson

Today we will learn how to use fact families for multiplication and division. Math helps us solve problems and understand the world around us.

Multiplication is a faster way to add equal groups. Instead of adding 3 + 3 + 3 + 3, we can multiply: 4 × 3 = 12. This means "4 groups of 3." The first number tells us HOW MANY groups, and the second number tells us how many are IN EACH group. The answer is called the product.

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.
