Most middle schoolers probably feel that quilting is at best an activity left to their grandmothers. This lesson uses the Zome modeling system to get them to realize how shapes in quilting are really tessellations and repeating patterns....

Sixth graders investigate tessellations and their origins. Students trace triangles to form a tessellation. They measure the angle of equilateral triangles. Students locate the line of symmetry, they create geometric squares,...

Students analyze symmetries of quadrilateral tilings and discover how various types of symmetries, used alone or in combination, can generate the same pattern in more than one way.

Students predict the number of cells after a series of cell divisions.  In this cells lesson students create a graph of their results and create a patterned drawing.
