In this multi-day activity, 3rd graders make 3 different models of an orphanage floor plan using Google Drawing, Virtual Graph paper, and a construction of rectilinear shapes, to calculate the area of each room using units square.

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.

Area is the concept of covering a region with "unit squares".

Fractions can be used to understand halves of a unit square.

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...

In this activity students will contribute a set of random points to a graph of a circle of radius 1 inscribed in a square. They will estimate the area of the circle using geometric probability.

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.
