Learning Objective

Students will be able to practice multiplication facts 11-12.

Today's Lesson

In this lesson, we'll explore how to practice multiplication facts 11-12. Mathematical thinking develops logical reasoning and problem-solving abilities.

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.

As you work through today's material, pay attention to the examples and try to identify the patterns or strategies being used. This will help you apply these concepts to new problems.

Take notes on key points and make connections to what you've already learned in previous lessons.
