In this exploring area activity, students sharpen their problem solving skills as they solve 6 story problems using the provided diagrams.

In this perimeter and area worksheet, students find the perimeter of various polygons.  They compute the perimeter, surface area, circumference, and volume of given figures.  Students explore trigonometric ratios.  This...

Seventh graders review the concept of finding the areas of a rectangle. This lesson uses the classroom as a real life application for the formula of area. They measure classroom in order to compute the area.

Fifth graders identify the area and perimeter of a rectangle. In this perimeter lesson plan, 5th graders use geoboards and rubber bands to construct various rectangles. Students use the formula to calculate area and perimeter of the...

Students explore area and perimeter. In this math lesson plan, students differentiate between area and perimeter and compute the area and perimeter of an object.

Four triangles are depicted for learners to construct on a geoboard. They compute and compare the areas, and so meet one of the sixth grade Common Core standards for geometry. Note that the set of triangles does not include a right...

Eighth graders plot points and investigate polygons. They locate a point, using ordered pairs of integers on the coordinate plane. Students compare geometric measurements and computations on coordinate axes as they are applied to...

Students find the area and perimeter of rectangular figures. They use this information to find patterns and discover relationships between area and perimeter. Students apply and explain formulas relating to perimeter, area, and volume.

In a series of lessons, examine the impact on humans by microcosms in the biosphere. Among the plans structured for students with different abilities and learning styles, are activities describing the symbiotic relationship, drawing the...

This is how long we mow the lawn together. The assessment requires the class to work with combining ratios and proportional reasoning. Pupils determine the unit rate of mowers and calculate the time required to mow a lawn if they work...
