Measurement, Perimeter and Area

Pupils figure out how to be resourceful when tasked with finding the area of a triangle knowing nothing but its endpoints. Beginning by exploring and decomposing a triangle, learners find the perimeter and area of a triangle. They then...

Are all the measurements scalable? Pupils work in groups or alone to determine whether figures are similar and find any missing side lengths. Then, they calculate the perimeters and areas of the figures. Finally, using the measurements,...

What kind of tree does a math teacher climb? A geometry! Here is a lesson that includes all the geometry resources you could ever wish for in one comprehensive workbook. Class members demonstrate what they have learned by determining the...

Test your mathematicians' skills with this full page of area and perimeter problems. Find the area and perimeter of different shapes including squares, parallelograms, trapezoids, and octagons. The formulas are not provided, so this...

Get your class thinking about geometry in their own bedrooms! Solving geometry challenges, individuals match words and definitions, find perimeter and area in their homes (rectangular, circular, and triangular), find circumference and...

In this perimeter and area worksheet, middle schoolers examine given perimeters and determine the dimensions that will give the maximum area.  This one-page worksheet contains four multi-step problems.

Investigate and compare scale factors of perimeter and area. Young scholars use an applet to manipulate the sides of similar rectangles. They then make perimeter and area calculations and compare the ratios to finish the second in a...

In this perimeter and area worksheet, students find the surface area of given polygons.  They determine the area of shaded regions.  This one-page worksheet contains 10 multiple-choice problems.  Answers are provided.

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.

It's hip to be square! The first of a two-lesson series combines computer simulation and physical manipulation to illustrate perfect squares. Partners use geoboards to measure the length of sides, perimeter, and area of squares....
