Students view a right triangle displayed by the teacher. Students measure legs and the interior angles of the triangle. They look for a pattern or relationship between the legs and angles. Students use pegboards and string to create more...

Young scholars observe and compare heat loss in various objects with surface area-to-volume ratios and transfer this comparison to the physical characteristics of animals in their environment. In small groups they conduct an experiment...

Young scholars calculate the amount of wrapping paper needed to wrap boxes. They describe how they determined their answers.

Students create three dimensional shapes using concept maps. In this geometry lesson, students investigate the impact of mental schemas on humans. They collect data on this topic and plot their data on a coordinate plane.

Students classify polygons by name and shape. In this geometry lesson plan, students identify the lateral surface of each conic. They differentiate between cones, cylinders and spheres.

Students describe environmental interrelationships using list of criteria. They are able to explain organism interaction, based on definitions provided. Also, students can use references and worksheets, to describe effects of pollution...

In this rectangular prism instructional activity, students find the volume and surface area of 3 rectangular prisms. Answers are included on page 2.

Ninth graders take a rectangular box (e.g., a cereal box) and cut it up to make a new, cubical box with the same volume as the original. In so doing, they will discover that because the cubical box has less surface area than the...

Fifth graders determine which container made from a single sheet of paper has the greatest volume. They look the solutions made by three different students before working on their own examples.

Students calculate the area of triangles using a variety of materials including computer applets.

Students plot a hiking course using aerial photos and a topographic overlay and find the latitude and longitude of absolute locations. They measure the total distance of a hiked area and figure the area of the ground walked using Heron's...

Students in a teacher education class address consumer related issues involving packaging. Using volume, surface area and graphs, they create a package for a given volume of a product. They design modifications for this lesson and to...

In this rectangular prism activity, students find the volume and surface area of 3 rectangular prisms; answers are included on page 2.

Young scholars calculate the length, width, height, perimeter, area, volume, surface area, angle measures or sums of angle measures of common geometric figures. They create an equation of a line of best fit from a set of ordered...

In this rocket worksheet, students calculate the burn rate for solid rocket boosters depending on exposed fuel area and burn depth. This worksheet has 2 problems to solve.

Students compare and convert units of measurement within the United States customary system and within the metric system by baking cookies. Students discuss how to double the cookie recipe, how to make only half of the recipe, and how to...

Use patterns to your advantage! The Pythagorean Theorem allows learners to find missing sides of right triangles. Problems include those with both rational and irrational lengths. 

Students investigate orthographic drawings. For this geometry lesson, students identify properties of three dimensional drawings in space. They solve problems using volume and area formulas.
