That still leaves the problem of memorizing a string of numbers, and here’s where the magic is. Teach children to skip count to the tune of a simple song. Have you ever wondered why children can learn the lyrics to songs so easily? It is because music can be used as a Mnemonic device, that is a strategy to assist with memorization. If you can associate the numbers with the sounds in a song, the children will not only learn them faster, but retain them much longer than they would memorizing them exclusively through repetition.
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.
