Illuminations: Multiplication: It's in the Cards

Multiplication: It's in the Cards

In this unit, students use the properties of multiplication to help them master the multiplication facts. The most effective and efficient way to help the students learn the number facts is to build an understanding of the operation, then encourage the students to use the helpful features of the number system, and finally to provide interesting activities for retention. This unit focuses on the second and third aspects of this learning process.

Math Content

• order property of multiplication
• multiplicative identity
• zero property in multiplication
• mastery of the multiplication facts

Individual Lessons

Lesson 1 - Looking for Patterns

Students skip count and examine multiplication patterns. They also explore the commutative property of multiplication.

Lesson 2 - Looking for Calculator Patterns

Students use a web-based calculator to create and compare counting patterns using the constant function feature of the calculator. Making connections between multiple representations of counting patterns reinforces students understanding of this important idea and helps them recall these patterns as multiplication facts.

Lesson 3 - More Patterns with Products

After using an interactive Web site to find patterns in the multiplication tables, the students practice multiplication facts and record their current level of mastery of the multiplication facts on their personal multiplication chart.

Lesson 4 - Keeping It All Together

By playing card games and using the The Product Game applet, students practice the multiplication facts. As students continue to master their facts, the teacher closely monitors their progress.
