Click a green flag, then click New and Roll! Wait while the wheel is rolling. You can try to guess where the wheel will stop before clicking Roll! by clicking on the number line. If the wheel stops near your guess, you will be congratulated. The purpose is to teach fractions as numbers in mathematics. Also works in Phosphorus i.e. w/o Flash: https://phosphorus.github.io/app.html?id=153790703
I was inspired by https://www.geogebra.org/m/b3dabM83 by Anders Karlsson, a Swedish math teacher. A later version of his program is https://www.geogebra.org/m/Dcb8TQ4j . I did write all code from scratch. It uses pi.
