Fact Families (Investigation)


Addition (+) and subtraction (-) are opposite operations in maths. 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



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.
