Tip the scale in your favor when learning about scale factors. After viewing a video clip of a learner trying to determine the scale factor of the areas of two rectangles, scholars consider how changing the dimensions of a rectangle...

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...

Does doubling mean everything doubles? Learners adjust the scale factor between two rectangles. Using the calculated measurements, pupils investigate the ratios between the lengths, perimeters, and areas of the rectangles.

Bring on the lights! Using an interactive, characters try to figure out how to light a skate park by examining area and ratios to determine the number of solar panels needed to power them. Pupils design a house with a roof to hold solar...

In this quadratic equations activity, 8th graders solve and complete 7 various types of problems. First, they find the area for each rectangle with a given perimeter. Then, students describe the shape of the graph and use the equation to...

Use this interactive tool to learn how to find the area of a rectangle. Click on "Instructions" for details on how to use this tool. Click on "Explore" for more ideas.

This multimedia Learn Alberta math resource looks at area and perimeter and how math is involved in the operations of a ranch. The accompanying interactive component lets students investigate a variety of rectangles to get a target...

Watch a student think through a problem about how the area of a rectangle changes when both sides are increased by the same scale factor and use online tools to demonstrate understanding of concepts related to area and scale factors in...

The interactive applet allows learners to explore the relationships between side length, area, and perimeter. Students see how changes in the scale factor influence the ratio of areas and perimeters. [Requires Java.]

This activity operates in one of two modes: auto draw and create shape mode, allowing you to explore relationships between area and perimeter.

Use this applet to find the perimeter of a variety of shapes with the same or different areas.
