## Graphing Points on a Coordinate Plane: Harry’s Feet Compete

Icon:

In this video from Cyberchase, Harry decides he needs to start a regular workout schedule. He uses a graph to record his progress. In the accompanying classroom activity, students play a ball-balancing game and record their attempts on a graph to build on the concepts presented in the video. This resource is part of the Math at the Core: Middle School Collection.

## Calculating Where Lines Intersect

Icon:

Learn how algebra can quickly determine the point where two lines intersect. This video focuses on setting linear equations equal to each other to find a common solution.

This video was submitted through the Innovation Math Challenge, a contest open to professional and nonprofessional producers and is part of the Math at the Core: Middle School collection.

## Hoop Dream: Use a Diagram to Solve Real-World Math Problems

Icon:

In this Cyberchase media gallery, a series of short videos shows how the Cybersquad diagram their own attempts to score a basket in a game called Jimaya Jam in order to win their release from confinement. In the accompanying classroom activity, student pairs play a game of their own called Player Plotting, in which students independently plot points on a coordinate plane and see if the diagrams they create from their points match.

## Points of Origin

This animation from KET illustrates how an origin is used for positive and negative measurement along a straight line and on a flat plane. It also shows how an origin, latitude, and longitude identify locations on Earth and explores how measuring temperature differs from measuring height or weight.
