Grade 1·1.OA.D.8

Find the Missing Number

Work out the missing number in each equation, then match it to its answer. The blank moves around — sometimes it's an addend, sometimes the number you take away, sometimes the total — so you get to think it through every way. Tap an equation, then tap the number that makes it true, and watch the pair link. Aligned to Common Core 1.OA.D.8 — finding the unknown whole number in an addition or subtraction equation, in any position.
