Roland O'Daniel on 15 Jun 10Nice set of applets that let students explore fraction understanding from multiple perspectives and models. I love that they use a variety of models for fractional development, including bars (multiple versions), sets, and linear. From the site: "Why Fractions? Fractions are one of the earliest stumbling blocks for students in math. Our goal is building conceptual understanding in fractions as a basis for comprehension in all later topics."
