Help children learn numbers with these engaging learning puzzles. Each set includes 20 four-piece puzzles featuring bright, colorful images and a color border to guide assembly. For numbers 1–20, they trace the numbers, count objects, and match magnetic numbers. Children can expand their learning by using the magnetic pieces on any magnetically receptive surface. Both sets include a write-on/wipe-off area for repeated practice, magnetic numbers, a dry-erase pen, and a fabric storage bag. Ages 4+.
