About this worksheet

Addition and subtraction are inverse operations, but young learners often treat them as separate lists of facts. First grade standards ask children to use that relationship to find unknown addends and understand subtraction as a missing-part problem. This worksheet repeatedly shows a whole and two parts, then asks which addition or subtraction fact can solve the unknown. The numbers stay small enough for accurate reasoning, while the arrangement changes so children do not rely on one template.

Some items begin with a subtraction fact and ask for the addition fact that proves it; others begin with an addition equation and ask which subtraction removes one part. Support pages use totals to ten. Standard and challenge pages extend into teen totals. Ask children to say the whole first and then name the two parts.
