Exploring Addition Fact Families within 10

The video tutorial introduces the concept of addition fact families within 10 using part-whole models. It demonstrates how numbers can be added in different orders to achieve the same sum, illustrating this with examples like 3 + 2 = 5 and 4 + 5 = 9. The tutorial encourages students to practice creating their own fact families and provides a template for writing number sentences. The video concludes with a review of a new fact family, reinforcing the concept through practice.

Which of the following is a correct representation of the fact family involving the numbers 3, 2, and 5?

• 3 + 2 = 6

• 2 + 3 = 5

• 5 + 3 = 2

• 3 + 5 = 2

In the fact family with the numbers 4, 5, and 9, which equation is incorrect?

• 4 + 5 = 9

• 5 + 4 = 9

• 9 = 5 + 3

• 9 = 4 + 5

What is the sum of 4 and 5 in the fact family discussed?

• 8

• 9

• 11

• 10

Which of the following is a correct number sentence for the fact family involving 6, 1, and 7?

• 6 + 1 = 8

• 1 + 6 = 7

• 7 = 6 + 2

• 1 + 7 = 6

In the practice exercise, which equation correctly represents the relationship between 7, 6, and 1?

• 7 = 1 + 2

• 1 = 7 + 6

• 6 = 7 + 1

• 7 = 6 + 1
