Arcs and Sectors 1.0 is known as a free yet very useful 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 program, students are given the radius or diameter of a circle, as well as the measure of a central angle, and must find the area of the circle, the area of the sector defined by the central angle, the circumference of the circle, and the length of the arc defined by the central angle. All answers are rounded to the nearest hundredth. You can view a screenshot of this program by clicking here.

A variety of simple math fact review activities including facts against a timer, building a number sentence and 11 different "math square" games. Many timed activities are accompanied by a "Hall of Fame."
We wrote this facts review program to eliminate some problems associated with paper work sheets. There is no copy machine, no hand correcting, and for students that have trouble with the pressure of timed tests, most of these puzzles allow them to practice independently with a timer. Best of all, these activities are perhaps a bit more fun than regular paper worksheets.
And what could be more fun that running an Aqua-style interface on a non-OSX PPC or Windows machine? Need to run your iMac lab under OS9 with only 256 colors? Hey, us, too. Specially optimized graphics insure that Aqua-style color gradients look good even at 256 colors.
