The Idea

The idea behind the Multiplication Machine called MarbleTime is to teach kids multiplication in an interactive and fun way. We did some research and found out ways that teacher's use in school to teach multiplication logic. The method that we found most interesting is the Grid Method. It helps children learn multiplication using a grid, so for example to do 3 x 2 you would have to create 3 rows and put 2 objects in each row and then do a total of all objects, that brings to a total of 6 in this case.

We like this idea for the following reasons:

1. It gives a sense of physical space.
2. You can visually see why 3x2 is 6 and would not be 5.
3. With a grid you can physically operate with objects.
