The LEA 3-D Puzzle is designed to help the child develop eye-hand coordination and learn to match and name the puzzle shapes. It can also serve as a neuro psychological assessment tool for patients with brain damage. The puzzle shapes are also symbols that are used later with various exercises designed to test the child’s vision for acuity and colour perception.   

The child can prepare at home by the age of 18 months to 2 years instead of the usual 3 to 4 years. The set includes the 3D puzzle set and an instruction manual to be used for guidance of parents.
