Adding Three Fractions 1.0

This is a free program taken from a CD-ROM collection of over 200 mathematics puzzles, available on the developer's Web site. Developed by a veteran teacher, these visually-oriented puzzle games have a simple interface and are designed to provide math problems in context to middle-school (grades five through nine) students.

In this particular puzzle, students choose one of two types of problems: ruler fractions (halves, fourths, eighths, sixteenths) or regular fractions. Students must add the given three fractions. Every problem is illustrated with an interactive sketch. You can view a screenshot of this program by clicking here.
