Fact Families and Their Equations

The video tutorial introduces the concept of fact families using a fun theme of haunted houses. It explains how numbers in a fact family relate through addition and subtraction, using examples to illustrate the concept. The tutorial provides instructions for a worksheet where students identify correct equations within fact families. Two detailed examples are given, each with a set of numbers, to demonstrate how to verify if equations belong to a fact family. The video concludes with a call to action to like and subscribe.

What is a fact family?

• A collection of numbers that are used in division.

• A group of numbers that can be added or subtracted to get the same result.

• A group of numbers that are unrelated.

• A set of numbers that are only multiplied together.

Which of the following equations does NOT belong in the fact family of 10, 7, and 3?

• 10 - 7 = 3

• 3 + 7 = 10

• 7 + 3 = 10

• 10 + 3 = 7

What should you do first when solving a fact family problem on the worksheet?

• Guess the answer.

• Make a fact family triangle.

• Write down random numbers.

• Start with subtraction.

In the fact family of 20, 5, and 15, which equation is correct?

• 20 - 14 = 5

• 15 + 5 = 20

• 20 + 5 = 15

• 5 - 15 = 20

Which number does not belong in the fact family of 20, 5, and 15?

• 5

• 15

• 6

• 20

What is the result of 20 minus 15 in the first fact family?

• 5

• 20

• 10

• 15

In the second fact family of 14, 8, and 6, what is 8 plus 6?

• 18

• 12

• 14

• 16

Which equation is incorrect for the fact family of 14, 8, and 6?

• 14 - 8 = 6

• 8 + 6 = 14

• 14 - 5 = 9

• 14 - 6 = 8

What should you do to ensure an equation belongs in a fact family?

• Verify all numbers are greater than 10.

• Make sure all numbers are prime.

• Ensure all numbers are even.

• Check if the numbers add or subtract to equal one another.

What is the result of 14 minus 6 in the second fact family?

• 12

• 10

• 8

• 6
