The Pixel Boards demonstrate representation, specifically image representation and how computers use numbers to represent images. Using black and white tiles 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. Great for dexterity and focus. This board is huge! With 256 marbles, images are more complex and detailed.
