The LEA 3-D PUZZLE^® is designed to support the development of the concept of "same," first with colors, then with black & white concrete forms that are prerequisites for the measurement of recognition acuity with the LEA SYMBOLS® tests at an early age. During play, you can also observe eye-hand coordination and awareness of direction which are often problems for children with brain damage, even mild brain damage. The package includes the booklet: Assessing Vision Development Through Picture and Shapes and instructions.

Dimensions: tray 6.75" x 6.75" (17.2 cm x 17.2 cm); each of the 4 symbol puzzle pieces 2" x 2" (5.1 cm x 5.1 cm).
