Decimal Snake

I learned from an interview with a 5th grader that he was struggling with ordering decimals. Ordering decimals requires an understanding of place value. I started thinking about a tool that can help him build a conceptual understanding of how decimal numbers are constructed. During our informal interview, I realized that he likes snakes. So, I decided to create a tool that is interesting to him and will attract his attention and have a  mathematical meaning to it. So, I decided to design a decimal snake. The decimal snake consists of 10 pieces. In each piece there will be 10 small increments representing a unit. Having 100 units on the snake will help us to represent decimals in tenths and hundredths place. I created the decimal snake in the hopes that it helps him visualize the meaning of each decimal.
