Connecting the Dots

Students focus on communicating precisely about transformations of polygons on the coordinate grid. They must think carefully about what information is needed (MP1) to describe a transformation in a clear, precise way. The coordinate grid plays a key role in this work, allowing students to effectively communicate the locations of polygons and how they are transformed. Note: This lesson includes a paper supplement.
