Drag and drop shapes into a puzzle to explore tessellations.

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.

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.

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

Students work in groups to build their own kite. The activity explores estimation, geometry, measurement, and patterns. The resource consists of a lesson plan, group activity instructions, lesson overview, and an expert page.

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.
