Simplifying fractions has been one of the major concern for most children. But, worry not! There is an easy explanation to it and we have it right here.
If you make your own, you can just draw three circles on a page and then 2-5 triangles on a page, and ask the child to match each circle with a triangle by drawing a line from shape to shape. Vary the shapes and the amounts. Sometimes the amounts should be equal, sometimes not.
