Linear Equations in Disguise
In the eighth segment of a 33-part unit, learners look at equations that do not appear to be linear at first glance. The equations are proportions where the numerators and denominators may have more than one term. To round out the...

Let the Matrix Do It
Young scholars create a matrix of the vertices of a triangle and produce new matrices that dilate, translate, rotate, and reflect the original triangle. After multiplying each matrix by a new scale factor, they graph the new matrix and...
Curated OER
Transformations-Shapes on the Move
Students examine transformations. In this math activity, students view and describe flips, slides, and turns. Students practice making transformations with shapes.
