Dog Gone Again!
Here is a real-life lesson! Learners must plan the dimensions of a rectangular fence to reign in a runaway dog. They survey what shape and size fence is needed and use formulas to find perimeter and area of the fence. They explore what...

Scaling Down Art
Students change the scale of a work of art using ratios, percentages, and proportions. While this is technically an art lesson, there is quite a bit of mathematics involved in converting to the correct scale.

Surface Area, Who Needs it?
In this geometry lesson on cylinders, geometers explore how to find the smallest surface area for a given volume. They use their knowledge to relate it to the real world by making a model of a livestock tank.

Determining Beam Stress and Deflection with COSMOSXpress
Students analyze cantilever stress using COSMOSXpress. For this engineering lesson, students calculate the beam's maximum deflection. They investigate the effect changing beam dimensions.

Let's Make a Compost Cake
Students create a compost cake. In this gardening and decomposition science instructional activity, students review and describe the "nutrient cycle." Students create a compost pile, measure and record the dimensions and temperature of...

Color Your World
Students calculate the cost of painting a room. In this surface area lesson, students create a scale model from provided dimensions of a bedroom. Groups use area formulas to find square footage, from which materials and labor costs are...

Area, Perimeter and Rations Using Pentominoes
Learners of all ages investigate area and perimeter through pentominoes. In this geometry lesson, students calculate the are and perimeter of different geometric shapes and describe the properties of similar and congruent shapes. This...

Two for One Box Company
Students draw a net (a two-dimensional pattern that can be formed to make a solid) for making an open top box on grid paper. They cut out the net and fold up each side to form the open box and tape the sides, then find the volume of the...

Beads, Balls, and Beakers
Students analyze the amount of space required to pack round objects. In this geometry lesson, students practice using space economically by practicing packing spheres into beakers. They then translate this concept to molecules being...

Deep Sea Drilling
Students explore ocean vessels that drill the ocean floor. In this ocean drilling lesson plan, students watch videos about drilling the ocean floor and discuss. Students get into groups, go outside and use string to mark off...

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.

How Big is the Playground: Creating a Map
Students create a topographical map of an area outside of the school. In this mapping instructional activity, students compile data on angles, distances, and key landmarks for a predetermined area on the school grounds to create a map...
Curated OER
Gazebo Construction
Students create and give oral proposals for the construction of a gazebo using a blueprint created with Geometer's Sketchpad. They then build a gazebo model using the blueprints created and provide evidence why it should be selected for...

Layering the Air
Students study the layer of the atmosphere. In this lesson on the atmosphere, students discuss the composition of the air around us and how the atmosphere was formed. Students create a scale model of the layers of the atmosphere.
