Source Institutions
Players take turns adding shapes made of three squares to a grid. They try to fit their shapes on the grid in a way that blocks the other player.
Buckets of Popcorn
Source Institutions
In this activity, learners develop an understanding of cylinders and volume as they compare two sizes of popcorn buckets.
Dots to Squares
Source Institutions
As learners play this strategy game, they develop understanding of squares, area, and perimeter. On each turn, a player draws a line between two dots next to each other on the grid.
Party Hat Symmetry
Source Institutions
In this hands-on activity, learners make New Year's Eve party hats out of wrapping paper. Learners use symmetry and measurement to cut out shapes they need to assemble the hats.
Magical Möbius
Source Institutions
In this tabletop activity (on pages 32-40), learners make Möbius strips -- 3D surfaces with only one side.
Crazy Shapes
Source Institutions
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.
Scaling Cubes
Source Institutions
In this activity, learners explore scale by using building cubes to see how changing the length, width, and height of a three-dimensional object affects its surface area and its volume.
Boredom Buster
Source Institutions
In this Cyberchase activity, use grid coordinates to share secret pictures with a friend. Color squares of a grid to make a picture (like a smiley face) that you keep hidden from the other person.
Throwing Pi
Source Institutions
In this calculus activity, learners use a classic problem of geometrical probability to find an important mathematical constant (pi).
Strengthen a Paper Bridge
