For children who find complex shape puzzles difficult, round and square puzzles are easier to manage. The round puzzle is 10 cm x 10 cm. The diameter of the circle is 6 cm. The round and square puzzle is 9 cm x 12 cm. The diameter of the circle is 6 cm. You can create a matching learning tool by attaching a favorite character to the circle and letters to the square, using pictures and letters of the child's favorite things. Round puzzles are easier to use when transitioning from three-dimensional ball/ball-toss games to a flat surface. Circles have no direction, so they are easier than ball-toss games. Ideal for learning to associate events with letters. Suitable for children in special needs schools and special needs classes. Children who cannot learn with paper cards can learn with this plywood material. Shipping costs are included. Whiteboard is not included.
