Made For Math Monday *Visual Fraction plates*
I taught 5th & 6th grades for a number of years. During that time I found that fractions, decimals and other associated concepts were particularly difficult for students because they were frequently not very comfortable seeing what the concepts would mean.
I got creative one weekend and made a cheap and easy to manipulate way of visualizing these concepts. I have used them in the classroom and with my own children, so I know they have worked for me.
One day on twitter a question was asked about how one could help students with these concepts and I recalled my plates. I knew I had them still (in my cabinet at work, though I'm sure there are a couple in my garage too) and I wanted to share them and how to make them. (here ya go, Mr_Stadel)
First I take 2 plastic plates (foam ones don't hold up and paper ones don't slide as well and they also don't hold up. The plates should be different colors, and I chose the 6 inch plates.
One the back I would mark particular angles on my own manipulative. This allowed me to quickly generate fractions (etc) that I wanted students to be able to identify by visual inspection
I would have students keep their plates in their desks and when I had time left in a lesson I would have them take them out and show me 25% red, or approximate 3/4ths blue or show me what 90% red would look like.
