Teach guess and check. Cover the blank with a sticky note, let your child guess, then test it by adding the guess to the answer shown to see if it makes the top number. If the sum is too high or too low, adjust and try again. A guess near the right size usually takes only two tries. When the first guess is often close and the check is automatic, move to three-digit numbers.
