Clusters should not be sorted from Major to Supporting and then taught in that order. To do so would strip the coherence of the mathematical ideas and miss the opportunity to enhance the major work of the grade with the supporting clusters.

Problem-Solving Tasks
This problem solving task asks students to find the area of a triangle by using unit squares and line segments.
Type: Problem-Solving Task
This task provides a concrete geometric setting in which to study rigid transformations of the plane.
Type: Problem-Solving Task
This problem solving task challenges students to find the perpendicular meeting point of a segment from the center of a circle and a tangent.
Type: Problem-Solving Task
Tutorials
Students will investigate symmetry by rotating polygons 180 degrees about their center.
Type: Tutorial
Students are shown, with an interactive tool, how to reflect a line segment. Students should have an understanding of slope and midpoint before viewing this video.
Type: Tutorial
This tutorial uses the midpoint of two lines to find the line of reflection.
Type: Tutorial
Students will see what happens when a figure is rotated about the origin -270 degrees. Having a foundation about right triangles is recommended before viewing this video.
Type: Tutorial
In this tutorial, students are introduced to the concept that three non-collinear points are necessary to define a unique plane.
Type: Tutorial
Before learning any new concept it's important students learn and use common language and label concepts consistently. This tutorial introduces students to th point, line and plane.
Type: Tutorial
This tutorial is great practice for help in identifying parallel and perpendicular lines.
Type: Tutorial
In this tutorial we will learn the basics of geometry, such as identifying a line, ray, point, and segment.

Virtual Manipulative
In this manipulative activity, you can first get an idea of what each of the rigid transformations look like, and then get to experiment with combinations of transformations in order to map a pre-image to its image.
