The Pixel Boards demonstrate representation, specifically image representation and how computers use numbers to represent images. Using black and white marbles as pixels, children create images based on simple numerical codes of 1s and 0s, and can design and code their own images. With 3 different sizes of pixel boards, children can see the change in resolution—as the number of pixels increases, so does the amount of detail. The Small Pixel Board is 4 x 4 squares, perfect for children as young as three to begin learning through play. 3+
