A great perceptual activity! Copy the patterns shown on the enclosed cards with the colorful 9 wooden pieces. Begin with a "night" version where you only see silouettes of the pieces and place the pieces in the correct position of 1 of the 3 pegs. AND/OR..., turn the pattern over and see the "day" version where everything is bright and clear and all the colors and shapes are clearly shown; now make the pattern. The 24 challenge cards vary in difficulty.
