Fact Families (Investigation)

Addition (+) and subtraction (-) are opposite operations in math. Because of this, we can write a group of related facts about a group of numbers which we call a fact family. 

So let's get rolling!

 

 

Activity: Roll & Write

Equipment

• 2 dice
• This fact family record sheet. 

 

What to do

1. Roll both dice. Write the numbers you roll on the fact family record sheet.
2. Using the numbers you rolled, write 2 addition number sentences.
3. Now you will have 3 numbers. Use these 3 numbers to write 2 subtraction number sentences.

 

I rolled two dice and got a 5 and a 3, so I filled in the first fact family on the sheet for you.
