The Greedy Triangle

Given a rectangle with specified dimensions, learners are prompted to create a new rectangle with the same perimeter, but a different area. This challenges third graders to think about perimeter and area in a new way. Each problem...

Given a rectangle with specified dimensions, third graders are prompted to create a new rectangle with the same area, but a different perimeter. This challenges learners to think about perimeter and area in a new way. Use...

Dawn, a fictitious student, drew a long rectangle shape in her math journal, and now your class will explore it! They find the measurements of each side, total the perimeter, and find the area. Consider using this as inspiration: have...

Each of these rectangles and squares has the length and width given with units. Can scholars solve for the area? Designed for beginners to this skill, all of these are whole-number single-digit measurements. There is a detailed example...

These rectangles have everything scholars need to find the area, but none of them has units. Beginners to this skill multiply the length and width, all of which are whole numbers, to calculate and record the area for each. Consider...

Turn young mathematicians into landscape architects with this four-lesson series on area and perimeter. Beginning with a basic introduction to calculating perimeter and area using non-standard units of measurement, this...

Perimeter is the total distance around an object. One can find the perimeter of a rectangle or square by adding all four side lengths together. These worksheets require third graders to find the missing side length, given the...

Does a shape's perimeter always match its area? Learners approach this and other claims in this shape investigation worksheet. Using blank grids, they draw various shapes based on required perimeter and area measurements, labelling the...

Young scholars explore the concepts of length, perimeter, and area. In this math lesson, students use Shape Explorer to practice finding length, perimeter, and area.

Area=length x width. Locate the value of the length of the rectangle and locate the given width and plug them in to solve. Don't forget to include the units and multiply them too. This three-minute video can be watched at home to review...
