What
people are saying about
Challenge Math... 
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 realworld 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, kidfriendly introductions to the
Pythagorean theorem, the "howtos" 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
worksheetdiscouraged and the mathematically
curious."

Think
1 


A
group of 24 college students decided to climb Mt.
McKinley. They bought enough food to last 20
days. If 16 additional students join them, how
many days will their food last? 


When you are
faced with a problem such as this, the best approach is to
Think 1. 


If
the food will last 20 days for 24 students, then for
1 student, that amount of food will last 20 x 24 or
480 days. Once you think about 1 person, the
problem becomes fairly easy.
