Which subtraction range is right for my child?
Basic facts (1–9) build fluency with small numbers; Within 20 adds the making-ten and counting-up strategies; Two-digit with borrowing introduces regrouping; Multi-digit extends it. Choose the range where your child is accurate but still thinking, and adjust it on the Subtraction Practice page.
How do I teach subtraction with borrowing?
Line up place values and start on the right. If the top digit is too small, regroup one ten as ten ones: 52 − 28 becomes 4 tens and 12 ones, so 12 − 8 = 4 and 4 − 2 = 2, giving 24. Once the steps are clear, try a few examples in a timed round.
What are common subtraction mistakes?
Subtracting the smaller digit from the larger one regardless of position, choosing the wrong digit when borrowing across zero, and losing track of the regrouped ten. The Review Mistakes list on the subtraction page collects these so they can be redone.
