Length, Perimeter, and Area

Area is the amount of space that takes up the inside of a figure. To find the area of a rectangle, one must multiply the length by the width. Here, third graders are challenged to find the missing side length, given the area.

Take young mathematicians on an exploration of the world of 3-D geometry with this seven-lesson unit. After first defining the terms perimeter, area, and volume and how they apply to the real world, students continue on...

For this perimeter, area and volume worksheet, 5th graders solve 6 word problems, then tell whether they found perimeter, area or volume.

Unfortunately for young mathematicians, the world isn't made entirely of parallelograms, triangles, and trapezoids. After first learning the area formulas for these common shapes, learners apply this new knowledge to...

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...

Have your learners practice finding the perimeter and area of geometric shapes using this resource. While just a simple review, this could be a wonderful way to solidify the concepts in their minds.

To find the whole, add and subtract the pieces. A portion of a massive geometry playlist shows how to approach finding the area of a composite figure. The resource works with a couple different composite shapes to find their areas.

What does a grid have to do with area? Well, just about everything! Learners view composite shapes on a grid and watch as the video instructor finds their areas. The examples use shapes composed of rectangles and triangles. Scholars...

Composite figures—because everything isn't shaped like a rectangle, triangle, or circle. Learners practice separating compound shapes into something more manageable. A video shows them how to make the calculations, and worksheets give...

Third graders find the area of rectilinear shapes by partitioning them into two non-overlapping rectangles and adding the areas of the non-overlapping parts together. It allows learners to recognize area as an additive.
