# Dilations Using Coordinates Math Games

In this series of games, your students will learn the effect of dilations, translations, rotations, and reflections on two-dimensional figures using coordinates. The Dilations Using Coordinates learning objective — based on CCSS and state standards — delivers improved student engagement and academic performance in your classroom, as demonstrated by research. This learning objective directly references 8.G.A.3 as written in the common core national math standards.

## Concepts Covered

Describe the relationship between the coordinates of the image and the pre-image under rigid motions. Dilations do not change angles. All lengths of line segments in the plane are scaled by the same factor when we apply a dilation. Dilations scale distances between points. Dilations of the same shape are similar. Dilations are transformations that expand or contract the plane of a given figure.

Describe the effects of dilating a figure using a scale factor. Describe the effects of rotating a figure using coordinates. Describe the effects of reflecting a figure over the x- or y-axis. Describe the effects of translating a figure n number of units using coordinates. In total, there are three games in this learning objective, including:
