How to Find the Area of a Trapezoid

Captivate your class by having them find the value of their names, different zoo animals, musical instruments, etc.,with a mental math lesson. Using the coding formula listed, children learn to fluently estimate and calculate...

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, students apply this new knowledge to...

Strengthen young geometric muscles with this exercise in finding surface area and volume. Six problems provide practice at determining the surface area and volume of two solid figures shown in cubic units, deciding which to find given a...

Combines mathematical measurement with gardening skills. Third graders hunt for worms in the garden and try to find the longest one. They also measure and weigh vegetables that they harvest from the garden, measure rainfall amounts,...

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.

A more challenging set of worksheets, third graders are required to measure area by counting whole and partial unit squares. Students will realize that two partial blocks make up one whole block. Each shaded figure is on a square unit grid.

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...

Extend young mathematicians' understanding of area with a geometry lesson on trapezoids. Building on their prior knowledge of rectangles and triangles, students learn how to calculate the area of trapezoids and other...

Third graders find area by tiling a rectangle based on the given side lengths. This helps learners visualize and create the area of a figure. From here, they can count the total number of tiles inside the rectangle to find the answer.

Third graders measure area by counting unit squares inside a rectangle.
