In this online math worksheet, students find the area and perimeter of rectangles. This excellent resource allows the students to check their answers, and to get "hints" should they run into difficulties. A terrific teaching tool!

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.

Tenth graders are provided instructions, including a video, on calculating the surface area of a prism. The one-page interactive worksheet contains two worked questions. Answers are included. 

In this area worksheet, students compute the area of circles, parallelograms and rectangles.  This one-page worksheet contains 5 multiple-choice problems.  Answers are provided in this online worksheet.

Using a slider, scholars build triangular numbers and their associated rectangles and use the geometric display to find the pattern to determine the next triangular number. They then relate that number to the area of the rectangle to...

In this geometry worksheet, 10th graders determine area and perimeter of rectangles, given the width and the length. The one page interactive worksheet contains ten questions. Answers and hints are included. 

Use a combination of tiling a rectangle to find area and find the greatest common factor of the lengths of two sides and the area they create. Pupils increase and decrease the sides of the rectangle before answer five questions...

Determine whether the soccer field has the right area. Pupils create a virtual soccer field based upon constraints. They determine the equation that models the area and continue to investigate other potential areas.

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 geometry learning exercise, 10th graders use algebra to solve geometry word problems involving the perimeter of a rectangle. The one page interactive learning exercise contains eight questions. Answers and hints are included.
