Media4Math Classroom is developing a series of instructional modules for reviewing SAT math topics in detail. These modules review the key skills that are tested on the SAT. In this module there is a thorough review of the topic of linear equations.

When a driver slams the brakes on a car, skid marks are created on the road. Accident investigators can measure the length of the skid marks to estimate the speed of the car. This involves using a quadratic function.

Rivers twist and turn as they make their way to the sea. Why does this happen and how can this be explained mathematically? In this module we look at the geometry of meandering rivers. In the process we'll discover some fascinating numerical relationships.

In this module explore the paths of fireworks and learn about quadratic functions. Students explore parabolas graphed in Quadrant I, with roots at the origin and positive x.

Why do we refrigerate food? To keep bacteria from ruining the food. Refrigeration slows down bacterial growth, allowing us to keep food in our homes for a longer time. But what happens when bacteria continue to grow even in a refrigerator?

The Archer Fish earns its name because it accurately sprays jets of water at insect prey, knocks them into the water, and has a quick meal. The ability to accurately do this has to overcome several geometric and physical challenges. In this module students explore these challenges in more detail.

Have you noticed how wrinkled an elephant's skin is? What purpose does it serve and what does math have to do with explaining this phenomenon? Well, the explanation for an elephant's wrinkled skin is almost entirely a math story.
