Everyone loves a challenge! Help children build confidence and achieve success with fun 2-piece puzzles that challenge them to learn 10 different shapes. Challenge learners to match everyday objects with their shape equivalents. The photos provide real-life learning. Only matching 7.5cm x 7.5cm pieces fit together, making these puzzles self-checking so young learners can play independently. The sturdy storage box holds 20 durable two-piece puzzles (40 pieces in total).
