In this activity, learners develop an understanding of cylinders and volume as they compare two sizes of popcorn buckets.

In this activity (on pages 41-47 of PDF), learners explore tesselating geometric patterns (repeated shapes, similar to the art of M.C. Escher).

This activity has three story puzzles learners can solve to learn about life in the Arctic.

In this tabletop activity (on pages 32-40), learners make Möbius strips -- 3D surfaces with only one side.

In this simple exploratory activity (1st activity on the page), blindfolded learners try to identify mystery items by smell.

In this activity, learners cut a shape into two equal sized pieces and use their knowledge of geometry and space to prove that the two parts are equal.

In this game, learners use clues to identify mystery shapes. Use everyday objects (like from the pantry) as the shapes.

In this activity, learners explore the size and scale of dinosaurs. Learners listen to "The Littlest Dinosaurs" by Bernard Most. Then, learners estimate the size of a Triceratops and T.

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

In this activity, reuse two-liter bottles to create bowling pins. Learners practice math skills and develop a concept of verifying answers, while bowling and keeping score.

In this activity about tangrams, learners print and cut out their own tangram shapes and solve puzzles by fitting these geometric pieces together in a variety of ways.

In this activity, learners build bridges using paper and explore how much weight each bridge design can support.

In this activity, learners take a turn contributing a closed figure made of six squares to a large grid; each must be different from all the others on the grid so far.

Create airplanes from straws and geometric shapes. Test them out to see how far they can fly, or how accurately they can be aimed.

In this classic memory game (on pages 37-45 of PDF), learners turn over tiles to reveal images on the back.

In this activity (on pages 49-54 of PDF), learners play with tangrams, a set of triangles, squares and a parallelogram that can combine into a larger square as well as all sorts of other shapes.

Is a square stronger than a triangle? Use tongue depressors to build simple shapes. Then apply a little weight to them and see what happens!

Use this activity to build division and number sense into any snack time or whenever there is a limited set of things to share among a group: If we deal these out, could everyone get two pieces?

Learners make a counting/estimating jar to exchange with friends or bring home.
