In this lesson students learn how to use the slope formula to calculate steepness. In particular, students learn how to calculate steepness in the context of cycling. Cyclists use a measure called grade to calculate the steepness of a hill or mountain. Students apply their knowledge of slope to the concept of grade.

In this module, students explore a physics-based application of linear functions: Hooke's Law. By exploring the properties of springs, a simple linear model is developed. Students then explore applications of Hooke's Law, from weight scales to bungee cords.

In this module students learn the basics of integers, with plenty of real-world applications to ground their knowledge. Two short videos introduce the topic of integers and how to graph integers on a number line. A real world application of Superconductivity is explored.

In this lesson students apply their understanding of linear functions to an analysis of distance vs. time functions. In particular students will: Define the function for finding distance given a constant speed. Graph the distance function and interpret slope, y-intercept, domain, and range.

In this Media4Math Classroom Module, your early elementary students will build on their counting skills by learning the skill of Skip Counting. Using graphics, videos, and games, students are introduced to the skill of Skip Counting and how it can help them improve the speed and accuracy of their counting. Specific examples include Skip Counting by 2's, 5,'s, and 10's.

In this Media4Math Classroom Module, your early elementary students will build on their counting skills by learning the skill of Counting On. Using graphics, videos, and games, students are introduced to the skill of Counting On and how it can help them improve the speed and accuracy of their counting. 

In this Media4Math Classroom Module, your early elementary students will build on their counting skills by combining Skip Counting and Counting On. Using graphics, videos, and games, students are introduced to more challenging counting scenarios that also pave the way for later developing their addition skills. Specifically, students are shown how to combine Skip Counting and Counting On to quickly and accurately count large numbers of items.

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.

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.

Americans manufacture, use, and recycle plastic products. In this module students look at data regarding the use of plastics in order to learn and apply skills related to place value.
