Customer Reviews (4.5 / 5 · 2 reviews)

Richard ★★★★★

I was skeptical at first, but these double-sided shells make word problems click for my second grader—she actually asked to do extra. The missing-number cards are her favorite, and I love that we can act out each story with the shells.

Penelope R. ★★★★☆

My first-grader, who usually hates math, actually asked to keep playing with this set. The double-sided cards give us a lot of variety, and making the word problems physical really helps him visualize the missing number. I just wish there were a few more cards for the trickier addition problems.
