Now we can use the chart to fill in the subtraction sentence and addition sentences below to make a fact family! First, let’s review what our chart is telling us.
Question 1:
Which numbers are the parts for this fact family?
Question 2:
Which number is the whole for this fact family?
Click each box to fill in the numbers where they belong!
Now we have the entire fact family with 6 as the whole and 2 and 4 as the parts!
We can use part-part-whole charts to fill out fact families like we just did for 6 - 2 = 4. Let’s try filling out subtraction and addition sentences to complete fact families using part-part-whole charts!
