How to approach subtraction facts
Subtraction can describe taking away, comparing, or finding a missing part. Students can count back, count up to the starting number, or break apart the amount being subtracted.
Connecting subtraction to addition helps students check answers: if 14 − 6 = 8, then 8 + 6 must equal 14.
