In this lesson students will practice finding the area of rectangular shapes and irregular shapes with right angles and understand why the area formula works for rectangular shapes. CCSS.Math.Content.3.MD.C.5.b A plane figure which can...

Count unit squares and partial unit squares to find the area of shapes. Students receive immediate feedback and have the opportunity to try questions repeatedly or receive step-by-step hints.

Practice finding the area of rectangles by counting unit square. Create rectangles with a given area by covering unit squares. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video...

This fifth-grade lesson explores the area of a rectangle with fractional side lengths. We tile the rectangle with unit rectangles and show that the area is the same as would be found by multiplying the side lengths. We multiply...

Eighth graders are presented with a drawing of a large square inscribed by a circle which is itself inscribed by a second square. They are asked to find the area of the circle outside the smaller square and compare it to the area of the...

This task challenges a student to use understanding of area to find the area of shapes on a grid.

Use this calculator to determine the volume, surface area, or other figure for a square pyramid, given the other numbers. Users set their parameters for two known variables of the pyramid and find what the unknown amounts would be.

Compare the amount of unit squares that cover figures. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video tutorial, or receive hints related to the concept of area.

This interactive exercise focuses on working with the radius of various circles to find the circumference and area as well as challenging you to find the distance a square wheel travels around the track.

Use this square calculator to find the side length, diagonal length, perimeter, or area of a geometric square. Given any 1 variable you can calculate the other 3 unknowns.
