### Off-Road Algebra

Here's an algebra resource that should interest (at least some) boys: Off-Road Algebra is a unit-study that revolves around the world of off-road motorcycle racing. The lessons fit pre-algebra and algebra, or approximately 9th grade.

For each of the 30 lessons, you view a video, then solve a problem. You'll also get printable explanations and solutions to all problems.

Glancing over the problems, they seem to cover a wide array of topics, such as miles per gallon, velocity, slope of ramps, GPS coordinates, decibels, acceleration, turn angles, lap times, and so on.
