In this activity, learners create three-dimensional shapes by making some origami models of simple boxes and containers.

In this activity, learners make different shapes that hold exactly one mole of gas (air).

In this activity, learners slide shapes to create unusual tiled patterns.

In this activity, learners construct three quick and simple mechanisms to start building a pop-up book. Learners fold, cut, and glue paper to make a bird beak, parallelogram, and V-fold.

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 three-part math activity, learners explore shapes. In part one, learners identify, describe, and classify two-dimensional shapes.

In this activity, learners repeat patterns in two and three dimensions to create tessellations. This activity combines the creativity of an art project with the challenge of solving a puzzle.

In this activity, learners follow simple directions to explore and create platonic solids.

In this activity, learners play a game and use pattern blocks to explore mirror images and reflection.

In this activity, early learners combine pre-cut recognizable shapes and their own abstract ideas to make representational pictures (e.g. houses, trees, shoes).

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

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.

In this group activity, learners make multi-sided polygons with string.

In this activity, learners use tangrams ( 7-piece puzzle tiles) to assemble a variety of shapes. Tangrams are ideal for improving spatial reasoning and geometry properties.

In this math activity, learners make toothpick designs by following simple patterns.

In this hands-on activity, learners use toothpicks to build different triangles and squares and then use the toothpicks to build and solve some tricky shape puzzles.

In this activity, learners practice drawing 3D structures in two dimensions. Learners draw cube stacks from five different points of view.

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