Best Fraction Strips EVER!
I bought a class set of these fraction strips from EAI for an amazingly low price because they were made for use with overhead projectors and were on a close-out sale. They are great for kids to manipulate. Each denominator is a separate strip, so any two strips can be moved to compare side-by-side. They are sturdy plastic and are much more kid-friendly than the fraction circles that I had been using.
The circles were really hard for the kids to put all the pieces together to make an actual circle. These are so easy to use!
