I created a tool that the children can use to concretely see that when you multiply decimals by powers of ten that you are moving the digits to the left or right of the decimal. I have many inclusion and some non-inclusion students who needed a more hands-on approach. I have many different approaches to help them learn and understand this standard.

I used a piece of oak tag and made slits to weave a sentence strip, cut in half horizontally. The kids move the digits right or left to see the pattern.

This is so smart! I was trying to think of a way to show this graphically and your idea is perfect. Thanks for sharing!

What a great manipulative! I teach special education math and I will definitely be using this to help my kids with place value and power of 10. My general rule of thumb: more hands on, the better. Thanks for sharing!

ReplyDeleteWhat a fabulous tool! Some of my 6th graders are struggling with multiplying by 10, 100, and 1000. The visual and tactile component hopefully will help students understand this concept (as well as dividing by 10, 100, and 1000).
