Help children learn letters, sounds, and 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 letters, kids trace each letter, practice its sound, and find matching magnetic letters to fit into recessed areas. For numbers 120, 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 letters or numbers, a dry-erase pen, and a fabric storage bag. Learn numbers through play and practice! Ages 4+.
