Five addition crosswords. Each equation fills five boxes, like 3 + 4 = 7, and runs across or down. Where two equations cross they share a number box, so the number written there has to work in both. Every equation has one or two empty boxes: start with one that has a single empty box, then use its answer in the equation that crosses it. Page 1 opens with a worked example, and the later pages have more equations that wait on a crossing answer. Some empty boxes are sums and some are missing addends. There is exactly one way to fill each puzzle.
Work the example on page 1 together and point at the shared box: the 5 belongs to both equations. Then let partners hunt for an equation with only one empty box and say why it is a good place to start. Counters or a number line help with the missing addends.
Ask your child to read each finished equation aloud, across and down, to check that it is true. If they get stuck, cover all but one equation and ask what number would make it true.
