Some things are hard to resist. Small collaborative groups build circuits and calculate the voltage using Ohm's Law. Budding engineers explore the connection between the voltage across different resistors and linear...

Keep track of your sixth graders' mastery of the Common Core math standards with this practice assessment. Taking a different approach than most standardized tests, this resource includes not only multiple choice questions, but also...

Unlock the mystery behind seasonal change with a collection of worksheets and activities. Whether they are drawing pictures of Earth's orbit around the sun or graphing the temperature and daylight hours of different locations...

Find the distance between points, graph points, and interpret data on coordinate planes to solve word problems. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

Try some coordinate plane word problems focusing on quadrant 1. Miss the problem, and Kahn offers some tutorials for help.

Practice graphing points like (-2, 4) on a coordinate plane. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

A set of four practice problems finding the points of quadrilaterals on a coordinate plane.

[Free Registration/Login Required] In this lesson, students will learn the basics of the coordinate plane including quadrants, x and y axis, ordered pairs and the origin. A 5 question quiz is included to see if they get it.
