Yo, yo, learn about vertical angles with a yo-yo. Using an interactive, scholars adjust the position of fingers holding a design from a yo-yo. Answering a set of challenge questions based on the interactive helps clarify understanding of...

Young scholars discuss the concepts of reflection, rotation, and translation. In this rotation activity, students investigate rotations through examples on an overhead projector. No additional worksheet or student assignment is included.

This lesson enables students to explore and measure the distance between blacks and whites in the past and present United States. By thinking about the intersections of whites, blacks, and others around the blues, students will deepen...

High schoolers use paper plates and detailed directions to build a model of the Michigan Avenue Bridge's gear system. By carefully measuring and cutting "teeth" for the gears of the "Gear Train," they create small gear that will...

Young mathematicians explore the concept of triangles as they construct altitudes of triangles to find the orthocenter. Learners construct their triangles using Cabri Jr. on their graphing calculators and find that the altitudes of a...

In this systems of equations worksheet, students solve each system of equations by graphing on a coordinate plane. Students identify the solution to the equations by the intersection of the two graphs. They also observe that parallel...
