Exploring Multiplication and Division Fact Families

This video tutorial introduces the concept of fact families, focusing on multiplication and division. It explains how arrays can be used to visualize and create multiplication and division facts, demonstrating that these operations are inverse. The tutorial provides examples of fact families using different sets of numbers and offers exercises for practice. The goal is to help students understand the relationship between multiplication and division and how to organize numbers to form fact families.

What is a fact family?

• A collection of multiplication tables.

• A set of random numbers.

• A group of related facts using the same numbers.

• A group of unrelated facts.

How are multiplication and division related?

• They are the same operation.

• They are inverse operations.

• They both involve addition.

• They are unrelated.

In a multiplication fact, what do the smaller numbers represent?

• The groups being brought together.

• The dividend.

• The total number of elements.

• The quotient.

What is the product of 2 rows of 3 circles each?

• 8

• 6

• 9

• 5

In division, which number do you start with?

• The quotient.

• The divisor.

• The total number of elements.

• The smaller number.

• 6

• 4

• 3

• 2

How many groups of 2 are there in 8?

• 2

• 5

• 3

• 4

What is the product of 4 rows of 5 each?

• 15

• 20

• 30

• 25

If you have 18 elements and divide them into groups of 9, how many groups do you get?

• 3

• 4

• 1

• 2

Why is practice important in mastering fact families?

• It makes you faster at calculations.

• It helps you understand the relationships between numbers.

• It helps you memorize the facts.

• All of the above.
