Tiling a Kitchen Floor

For Teachers 9th - 12th Standards
Cover the floor with math. Pupils work to determine the proper shape to cover a kitchen floor. They first determine the number of tiles to purchase and configure their placement to reduce the amount of waste. Teams finish by creating a...

Area Builder

For Students 3rd - 6th Standards
All that matters is the tiles. Pupils use the interactive to investigate the relationship between area and perimeter using tiles. The interactive has an explore and a game mode to accommodate different steps in learning. The game mode...

Teaching Geometry Through Play

For Teachers 6th - 12th Standards
Puzzle your way through to a new understanding of area. Scholars learn about the area of polygons through equidecomposability, the idea that polygons that can be decomposed into the same set of pieces have the same area. By using...

Proving the Area of a Disk

For Teachers 9th - 10th Standards
Using a similar process from the first lesson in the series of finding area approximations, a measurement resource develops the proof of the area of a circle. The problem set contains a derivation of the proof of the circumference...

Properties of Area

For Teachers 9th - 10th Standards
What properties does area possess? Solidify the area properties that pupils learned in previous years. Groups investigate the five properties using four problems, which then provide the basis for a class discussion.

What Is Area?

For Teachers 9th - 10th Standards
What if I can no longer justify area by counting squares? Lead a class discussion to find the area of a rectangular region with irrational side lengths. The class continues on with the idea of lower approximations and...

The Scaling Principle for Area

For Teachers 9th - 10th Standards
As they investigate scaling figures and calculate the resulting areas, groups determine the area of similar figures. They continue to investigate the results when the vertical and horizontal scales are not equal.

Is There Mystery in Measurement?

For Teachers 3rd - 6th
Investigate perimeter and area of polygons! In this measurement activity, learners use index cards to create rectangles and trace their hand to estimate its area and perimeter.
