The Boxes Go Mobile
Source Institutions
Learners display their findings after a study of surface area and volume. They build a mobile to show a commercially available box and a constructed cubical box of the same volume.
Fill It Up
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.
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.
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.
The Shadow Knows II
Source Institutions
In this activity, learners will measure the length of a shadow and use the distance from the equator to calculate the circumference of the earth.
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.
Six Squares: Geometry and Design
Source Institutions
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.
Solving Playground Network Problems
Source Institutions
In this activity, learners use cooperation and logical thinking to find solutions to network problems on the playground.
Dowels and Rubber Bands I
Source Institutions
If you have 3-foot dowels and rubber bands, you can can started on this fun and open design challenge. You can make structures big and small: make it so you can fit your parent into it!
Exploring Tessellations (Grades 6-8)
Source Institutions
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.
Close It Up
Source Institutions
As learners play this challenging strategy game, they build understanding of area and perimeter. On each turn, a player draws a line between two dots next to each other on the grid.
Four in a Line
Source Institutions
This strategy game has simple rules but can be a challenge. Players start with an empty hexagonal grid. On each turn, a player initials one empty hexagon on the grid.
New Boxes from Old
Source Institutions
Learners determine the surface area and volume of two identical boxes, and then figure out the dimensions of a cubical box with the same volume.
Hand Biometrics Technology
Source Institutions
In this activity, learners explore how engineers incorporate biometric technologies into products as well as the challenges of engineers who must weigh privacy, security and other issues when designin
