### REVIEWS

*Reviewed in Home Education Magazine Nov.-Dec. 2000**"...the intent here is not problems for the sake of rote practice, but problems to encourage thought and interest, and to give kids a feel for the many fascinating real-world uses of math. Metric conversions are demonstrated with measurements of elephant tusks, viruses, and the wingspans of ancient dragonflies; statistics explained with examples taken from medical research; ratios and proportions taught with jumping fleas, metal alloys, map scales, and the heights of trees. All the basics are here too: for example, kid-friendly introductions to the Pythagorean theorem, the "how-to's" of dividing fractions and coordinate graphing, the distinctions among sine, cosine, and tangent, the formulas for calculating the volumes of cylinders and spheres.**Challenge Math is a great resource for the worksheet-discouraged and the mathematically curious." - Becky Rupp, Ph.D.**Finally, I have a curriculum for my brightest math students that really challenges them and develops their problem solving skills.**- Teacher of talented and gifted**I'm an elementary teacher, so I have to laugh---my son is so excited about doing these problems that I find myself saying to him that he'll need to limit himself to two hours or less of math per night.**- Parent of 6th grader**Invaluable as a classroom math program enrichment resource, Challenge Math is also and ideal and highly recommended resource for home-schooled students as well."**- Wisconsin Book Watch*
