Geometry and Spatial Relations: Sidewalk Capers
Source Institutions
In this math lesson, learners use a variety of manipulatives to explore spatial relationships of squares and their transformations.

Geometry: Let's Face It
Source Institutions
In this math lesson, learners identify, describe, and construct the five regular polyhedra.
Soaring Towers: Building with Recycled Materials
Source Institutions
In this activity, learners will build the highest tower they can out of recycled materials.

Mold Mole Molds
Source Institutions
In this activity, learners make different shapes that hold exactly one mole of gas (air).

Geometry: Tiling the Plaza
Source Institutions
In this math lesson, learners arrange pattern blocks to create tessellations and to explore geometric patterns. Learners first explore making patterns with a variety of pattern blocks.
Build a Super Structure
Source Institutions
In this activity, learners use things from the kitchen as building materials to explore how shapes contribute to the strength of different structures.

String Shapes
Source Institutions
In this activity, learners work together to make polygons (many-sided shapes) with string. Learners sit on the floor and hold onto a piece of string slid between their thumbs and index fingers.

Geometry Construction: Polyhedral Playthings
Source Institutions
In this activity, learners create 3D geometric shapes using straws and pipe cleaners.

The Four-Square Quilt
Source Institutions
In this activity, learners arrange triangles together to make patterns to create paper quilts. Learners experiment with arranging the triangles in different ways to make various designs.

Making a Translation Tessellation
Source Institutions
In this activity, learners slide shapes to create unusual tiled patterns.

Simple Pop-Up Mechanisms
Source Institutions
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.

Patterns and Relationships: The Magic Box
Source Institutions
In this math lesson, learners participate in a variety of activities that give them experience in recognizing, describing, and extending repeating and arithmetic patterns.

Geometry and Spatial Relations: It's a Perfect Fit
Source Institutions
In this three-part math activity, learners explore shapes. In part one, learners identify, describe, and classify two-dimensional shapes.

Exploring Tessellations (Grades K-2)
Source Institutions
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.

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

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

FAMILY MATH on the Go
Source Institutions
This assortment of mathematical games can be played while traveling.

Mixing in Math Moments: Several 5-10 Minute Math Activities
Source Institutions
This website contains several activities. Mixing in Math Moments are activities that take 5-10 minutes that keep learners occupied, learning about the world, and using math on their own.
Building Houses: Build a Cardboard Tube House
Source Institutions
Build a house you can fit inside, using cardboard tubes.

Exploring Tessellations (Grades 3-5)
Source Institutions
In this activity, learners repeat patterns in two and three dimensions to create tessellations.
