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...

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...

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,...

In this ratio, perimeter and area worksheet, students find the scale factor of similar rectangles. They identify the ratios of their widths and lengths. Students justify their answers through written explanations. This two-page worksheet...

Students determine the relationship between perimeter, circumference, area, surface area, and/or volume of similar figures and their parts. They complete activities related to the question. Answer key included.

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...

Learners of all ages investigate area and perimeter through pentominoes. In this geometry instructional activity, students calculate the are and perimeter of different geometric shapes and describe the properties of similar and congruent...

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.

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...
