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.
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.
Incredible Shrinking Shapes
Source Institutions
In this activity, learners get hands-on experience with ratios and scaling while making their own jewelry out of recycled plastic containers.
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!
Construction and Destruction
Source Institutions
In this three/four-day lesson, learners calculate perimeters and areas and draw the castle plan to scale.
Arctic Sea Ice
Source Institutions
In this activity, learners explore how the area of Arctic sea ice has changed over recent years. First, learners graph the area of Arctic sea ice over time from 1979 to 2007.
Geometry and Algebra: The Future Flight Equation
Source Institutions
In this activity, learners discover how NASA engineers develop experimental aircraft.
Giant Museum: Create a Scale Model
Source Institutions
In this activity, learners will predict the size of a giant scale model of a comb or other rectangular object, then make one. If you tripled the size of a dollar bill, could you sit on it?
Twelve at a Time
Source Institutions
As learners play this game, they build skills in area, perimeter, multiples and factors. They take turns making rectangles with 12 squares on the grid.
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.
Mystery Jars: Make Your Own: Estimating and Counting
Source Institutions
Learners make a counting/estimating jar to exchange with friends or bring home.
Cylinders and Scale
Source Institutions
In this activity, learners investigate the relative growth of lengths, areas, and volumes as cylinders are scaled up.
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.
Greeting Card Boxes
Source Institutions
In this activity, learners make cool boxes out of old (or new) greeting cards or postcards.
Inverse Square Law
Source Institutions
In this math activity related to light, learners explore why a light, such as a candle or a streetlight, looks dimmer the farther away from it we get.
Computation and Estimation: Roll Out The Barrel
Source Institutions
In this math lesson, learners apply mathematical modeling to solve a real-world storage problem, in which a manufacturing company is given two options for storing oil barrels.
Air Pressure and Dent Pullers
Source Institutions
In this activity, learners simulate Otto von Guericke's famous Magdeburg Hemispheres experiment.
