This is my favorite way to teach fractions, play dough. It's simple and effective. I have the kids roll out shapes (circles are the easiest way to start) and have them make cuts. At first, I tell them how many sections to cut. So if I made one cut down the middle of the circle that would still be a 2 out of 2 pieces. Take one piece out and that is 1 out of 2 or 1/2. We do this with many sections until they get the hang of what a fraction really means. Once they get it, I tell them to make a fraction like 7/10 and see if they really understand. This is great for those hands on learners but for other learning styles as well.
