These activities will allow students to discover the concepts of geometry through shape exploration and the creation of choreographic sequences.

Looks at the lines of symmetry in different types of polygons. Includes ten practice questions. Each question is accompanied by an explanation of the answer.

This task challenges a students knowledge of 2-dimensional geometrical shapes to sort shapes and to design a shape that has a given set of attributes.

Can you help Wally the wizard practice some of his tricks while you learn about symmetry and 2D shapes?

This task challenges a student to demonstrate understanding of the attributes of two-dimensional shapes.

This task challenges a student to use knowledge of geometrical attributes to identify and describe shapes.

Students read the clues to determine the shape the clues are describing. If they choose the correct shape a smiley face appears.

Kyan is an African villager. Can you help him name and define different parts of shapes?

I love blending art and math. I want my students to develop a depth of knowledge for 2D plane shapes and distinguish polygon from non-polygon shapes.

In this lesson on transformations on coordinate planes, 8th graders explore dilation, translation, reflection, and rotation of shapes within a coordinate plane.

Determine the planes of symmetry of a shape.

In this activity, students use the pen feature of the calculator to draw geometric shapes in a coordinate plane.

Given a figure on the coordinate plane and the definition of a rotation about an arbitrary point, draw the image of that rotation. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video,...
