In this activity, learners design unique tiles and make repeating patterns to create tessellations. This activity combines the creativity of an art project with the challenge of solving a puzzle.

Use geometry, a ruler, and a steady hand to create these amazing unfurling paper folds!

In this activity, learners repeat patterns in two and three dimensions to create tessellations.

In this math lesson, learners explore tessellations through literature, music, writing, and art activities.

In this activity, learners construct a projector out of cardboard to view their favorite images (such as storybook illustrations) on the wall.

In this math lesson, learners use the setting of a flower-making fundraiser to explore a variety of patterns. Learners examine the patterns in a flower design made of triangles surrounding a square.

In this activity, learners explore the concept of rotational equilibrium. Learners work in teams to estimate and determine the force within a mobile design.

In this activity, learners construct a device that projects images onto a surface, so they can trace landscapes and other sights.

This activity (on page 2 of the PDF under SciGirls Activity: Kites) is a full inquiry investigation into how a kite’s shape affects its performance.

In this math activity, learners use a variety of sensory modalities to gain experiences with identifying, describing and creating repeating patterns.

In this math lesson, learners participate in a variety of activities that give them experience in recognizing, describing, and extending repeating and arithmetic patterns.

In this activity, learners build a paper stellated rhombic dodecahedron, a three-dimensional 12-pointed star.

In this activity, learners create 3D geometric shapes using straws and pipe cleaners.

In this activity, learners construct a device that allows them to view 2-D images in 3-D.

In this activity, learners explore how the process of folding has impacts on engineering and is evident in nature.
