Bill Nye's Solving for X - Pre-Algebra 1, Volume 1Spring 2010 DVD
In his first segment, he's in a kitchen making waffles and has a recipe that he's trying to cut in half. So how does he figure out what half of 1 and &frac13 cups of flour is? He explains it through fractions, written out on a recipe book. It's an excellent way to illustrate the point, with a food kids love.
His next segment, about exponents, shows him sitting at a sidewalk café. At first he uses his napkin to explain the concept of two times two, but finally he uses a chalkboard to write it all down and show what exponential numbers look like. Video editing to exponentially reproduce images of himself helps drive home the point.
Bill is wacky and full of energy, and if there's a fun way to teach a math concept, he'll be the first to come up with it. With Disney's eye for appealing to kids and Nye's ability to teach the math, the execution is just right. Our only quibble: Are the segments too short to really fully explain the concept? Use the DVD as a teaching tool to enhance or further illustrate a concept, but don't expect Bill to replace the teacher.
