About This Lesson
It explains and provides a very simple grid coined the Ratio Reckoning Machine; for children to calculate ratios. It can be used for a basic question such as the number of different color apples in a bag to a more complex ratio which involves different units usually featured in a recipe. It is just a start and I need to add more problems.
I am going to show this to the math teacher at my school. I think she will like it. Have you thought about publishing it on a DVD?
