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 an equilateral triangle.
Type: Problem-Solving Task
This task asks students to show how certain points on a plane are equidistant to points on a segment when placed on a perpendicular bisector.
Type: Problem-Solving Task
This is a reasonably direct task aimed at having students use previously-derived results to learn new facts about parallelograms, as opposed to deriving them from first principles.
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
This task is intended to help model a concrete situation with geometry. Placing the seven pennies in a circular pattern is a concrete and fun experiment which leads to a genuine mathematical question: does the physical model with pennies give insight into what happens with seven circles in the plane?

Type: Tutorial
In this video, students will learn how to use what they know about the sum of angles in a triangle to determine the sum of the exterior angles of an irregular pentagon.
Type: Tutorial
In this tutorial, students prove that vertical angles are equal. Students should have an understanding of supplementary angles before viewing this video.
Type: Tutorial
Students will use algebra to find the measure of vertical angles, or angles opposite each other when two lines cross. Students should have an understanding of complementary and supplementary angles before viewing this video.
Type: Tutorial
In this tutorial, students will use their knowledge of supplementary, adjacent, and vertical angles to solve problems involving the intersection of two lines.
Type: Tutorial
Lets prove that the sum of interior angles of a triangle are equal to 180 degrees.
Type: Tutorial
Let's find the measure of an angle, using interior and exterior angle measurements.
Type: Tutorial
