Exploring Addition and Subtraction Fact Families Within 10

The video tutorial introduces the concept of fact families within 10, using part-whole models to demonstrate how numbers relate through addition and subtraction. It provides examples with numbers 4, 3, and 7, as well as 4, 2, and 6, showing how different number sentences can be formed. The tutorial encourages viewers to create their own fact families using a provided template and concludes with a review of the concept using another example.

What is a fact family in mathematics?

• A set of numbers that are only used in multiplication.

• A series of numbers that are unrelated.

• A group of numbers that are related through addition and subtraction.

• A collection of numbers that are used in division.

Which of the following is a correct fact family for the numbers 4, 2, and 6?

• 4 + 2 = 6, 2 + 4 = 6, 6 - 2 = 4, 6 - 4 = 2

• 4 + 2 = 8, 2 + 4 = 8, 8 - 2 = 6, 8 - 4 = 4

• 4 + 2 = 6, 2 + 4 = 8, 6 - 2 = 4, 6 - 4 = 2

• 4 + 2 = 6, 2 + 4 = 6, 6 - 2 = 2, 6 - 4 = 4

If you have a part-whole model with the numbers 7, 3, and 10, which of the following is NOT a correct number sentence?

• 7 + 3 = 10

• 3 + 7 = 10

• 10 - 3 = 7

• 10 - 7 = 4

What is the missing number in the fact family: 5 + 3 = 8, 3 + 5 = 8, 8 - 3 = 5, 8 - ? = 3?

• 5

• 4

• 7

• 6

Which statement is true about fact families?

• They include multiplication and division sentences.

• They only include addition sentences.

• They only include subtraction sentences.

• They include both addition and subtraction sentences.
