Curated OER
The Estimation Station
Students challenge "common knowledge" against newly learned estimation strategies and put those strategies into use. They consider variables in estimating different groups of objects and practice skills of representing numbers.
Curated OER
Density and Buoyancy Lesson Plan
Students investigate why some objects float or sink in water. In this physics lesson, students calculate the density of clay ball using a mathematical equation. They write a complete lab report about the experiment.
Curated OER
Introduction to Estimation and Making Arrays
Students explore the concept of estimating and organizing a group of objects into an array to count the exact number of items. They create their own arrays and practice elements of estimation.

What's Your Design?
Sixth grade students: design a stained glass window, submitting their initial plan detailing the measurements of all lines and angles. Seventh grade students: create a scale drawing of their own geometric family of four members.
Curated OER
Shape Toss
Young scholars get a bounce ball and find a Polyspot. On the teacher's signal, students underhand throw to a target. They keep their own score: one point each time they hit a target.
Curated OER
CO2 Blow Out!
Fifth graders determine that carbon dioxide is a gas given off during respiration and that oxygent is the gas that is absorbed during respiration. They determine the air capacity of the lungs.
Curated OER
How Are Magnetic Fields Related To Sunspots?
Students discover that sunspots are the result of intense magnetic forces on the photosphere of the sun by observing images from the SOHO satellite.
Curated OER
Polygons, Pingos, and Themokarst! Oh MY!
Students complete activities to learn about the common land features in Alaska. In this land study activity, students study an overhead for permafrost features. Students define ice wedge polygons, thermokarst, and pingos. Students also...
Curated OER
Geometry Scavenger Hunt
Students use the digital camera, identify geometric shapes (in nature as well as man-made), and gain a better understanding of geometric vocabulary. They search for and recognize geometric shapes in unusual settings
Curated OER
Creating Gardens
Students are shown that numeracy is all around them. They use volume, and calculate the quantity of soil required to make a garden to given instructions. Students are asked how to calculate the amount of soil required for the garden.
Curated OER
Estimation
Students complete computer activities about estimating if items are more or less than a given amount. For this estimation lesson plan, students also estimate measurements around the classroom.
Curated OER
The Pacific Ocean
In this Pacific Ocean worksheet, students read 2 pages about the Pacific Ocean and answer true and false questions. Students answer 10 questions.
Curated OER
Geometry Geopardy
Third graders participate in a game in order to review geometric concepts.
Curated OER
Mapping a Stream
Pupils map an actual local waterway. They create full color scale drawings that include windfalls, plant cover, streambed composition, and landmarks such as trees, boulders, and slumps. This is a long-term project that involves...
