This blog gives an overview of the design process for a tangible user interface that teaches kids multiplication in an interactive and fun way. It uses Grid Method, which helps children learn multiplication using a grid, where to do 3 x 2 you would create 3 rows & put 2 objects in each row, then do a total of all objects. This method was used as it gives a sense of physical space, you can visually see why 3x2 is 6 and would not be 5, and with a grid you can physically operate with objects.
