Each problem generated by this applet states two fractional endpoints for a line segment. The student representations each fraction by subdividing and coloring areas displayed as either circles or squares. The applet indicates if a colored area correctly represents the fraction. Finally, the student must model and name in the lowest terms a fraction between the two given fractions. The applet allows students to either work with circles or squares and can keep the student's score for a series of problems. From the applet page, What, How, and Why buttons open sections that explain the activity's purpose, function, and where the mathematics fits into the curriculum, as well as lists the related NCTM standards. Also included are student handouts and discussion questions about approximating fractions and whether it is easier to reduce a fraction expressed as a square or circle.
