Geometry and Spatial Relations: Mirror, Mirror
Source Institutions
In this math lesson, learners use hinged mirrors to discover that regular polygons are composed of triangles tessellating around a center point.
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.
Buckets of Popcorn
Source Institutions
In this activity, learners develop an understanding of cylinders and volume as they compare two sizes of popcorn buckets.
Step Into Cyberspace
Source Institutions
In this activity, learners discover that they can modify a regular piece of paper so that it's large enough for them to walk through!
Number Sense and Computation: Soak It Up
Source Institutions
In this math lesson, learners compare products to determine the best product.
Exploring a Complex Space-Filling Shape
Source Institutions
In this activity, learners build a paper stellated rhombic dodecahedron, a three-dimensional 12-pointed star.
Shape & Solid Exploration
Source Institutions
In this game, learners use clues to identify mystery shapes. Use everyday objects (like from the pantry) as the shapes.
Memory Match
Source Institutions
In this classic memory game (on pages 37-45 of PDF), learners turn over tiles to reveal images on the back.
The Right Fit
Source Institutions
In this math activity, learners trace their hands and estimate the number of beans that can fit into their hand tracings. Then, learners glue the beans to the tracing to test out their estimations.
Peppy's Day in the Park
Source Institutions
In this math activity, learners build Peppy the dog the best trail and park for running around.
Determining the Amount of Transpiration from a Schoolyard Tree
Source Institutions
In this activity, learners calculate the number of milliliters of water a nearby tree transpires per day.
Tangram Challenge
Source Institutions
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.
Patterns and Relationships: Struts 'n Stuff
Source Institutions
In this math lesson, learners identify the relationship between the number of sides in a regular polygon and the number of struts needed to make each polygon rigid.
Making a Translation Tessellation
Source Institutions
In this activity, learners slide shapes to create unusual tiled patterns.
Make a Model of a Home Made From Shipping Containers
Source Institutions
In this activity, learners watch a video to learn about a couple who built a home out of shipping containers in Brooklyn, New York.
Subtracta's Dog
Source Institutions
In this math activity related to volume, learners use problem solving skills to calculate and build a model house for Minus the dog.
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.
