The classic light-up pegs have been upgraded to become a formidable machine to teach children about “computational thinking” and “coding unplugged”. Computational thinking is the ability to break down a complex problem into different parts in order to make it easier to solve. Coding unplugged teaches the basic principles of programming without using electronic devices. There are two ways to play: in the first, you create mosaics following the patterns on the illustrated side of the cards. In the second, you create mosaics following the algorithm on the “coding” side of the card. Once the mosaic is complete, the transparent Peg Brite pegs light up like coloured lightbulbs.
