Subtract a 1-Digit Number — Missing Number: how to help at home or in class

Pose a little puzzle: a jar held 71 buttons, some were used, and 66 are left. Your child counts up from 66 to 71 on their fingers to find how many were used. Because the gap is under 10, counting up is quick. Then swap and let your child invent the puzzles. Finish by adding the answer back to check. When this feels easy, two-digit missing numbers are the next step.
