In this perimeter and area worksheet, students calculate the perimeter and area of rectangles that are measured in centimeters containing numbers with decimals. Students complete 4 problems.

In this area of a parallelogram activity, 10th graders determine the measurement of 10 different parallelograms illustrated. First, they multiply the base of the parallelogram times its height to determine the area. Then, students...

Learners follow a series of instructions for drawing and coloring different shapes in order to learn the difference between the perimeter and area of a polygon. Then they are asked to find the perimeter and area of a 3x4 rectangular...

Activate your geometer's minds with area calculations, some of which are tricky. First, they solve five word problems dealing only with rectangular shapes. The next five use irregular shapes with side measurements given. Scholars solve...

Use this geometry review worksheet to have learners complete nine problems involving transformations, area, volume, and unit conversions. They answer one multiple choice question on estimating lengths.

There is only one area calculation problem here, and the explanation is detailed below; consider projecting this as an all-class warm up. Scholars assess a rectangle with given length and width, calculating its area. Next, they break it...

Third graders engage in an enrichment lesson exploring the concepts of area and perimeter. They construct new pentominoes that are 3 times the size of normal ones and then identify the area and perimeter measurements. They then create a...

For this online math worksheet, students solve a variety of geometry problems which utilize parallelograms. This excellent resource allows the students to check their answers, and to get "hints" should they run into difficulties. A...

Upper graders investigate how to find the surface area when using two-dimensional shapes. They conduct an investigation in groups while working sample problems given during class discussion with the teacher. They also review how to...

Elementary schoolers complete word problems dealing with the different kinds of measurements of different shapes. They solve 10 problems including perimeter, angles, volume, and more.

In this online math activity, students determine the length and width of given rectangles given their area. This excellent resource allows the students to check their answers, and to get "hints" should they run into difficulties. A...

Teach your pupils to calculate the area of different polygons. Learners create formulas to solve their problems. They use the TI navigator to graph their shapes and observe the change in area.

Upper graders represent multiplication of a two-digit number by a two-digit number as the area of a rectangle with dimensions of the two factors. They find patterns for the number of different base ten blocks in a rectangle representing...

Fourth graders explore how to find the area of a rectangular object. As a class, they discuss definition of area and strategies for finding area. The teacher models finding the area of an object by counting squares. Students observe...

Students calculate the area of different polygons. In this geometry lesson, students explore polygons based in their shape and number of sides. They find the formula for the area and use each specific formula for each shape.

In this area of rhombus instructional activity, students find the area of rhombus whose diagonals are given, 4 total. Work space is provided. Answers are included on page 2.

In this geometry learning exercise, 4th graders calculate the area of 3 rectangles using the l x w x h formula. They work with the measures of centimeter, feet, and meters.

In this mathematics worksheet, students give the area and perimeter of each polygon illustrated on the sheet. There are six different polygons to measure on the sheet.

In this online math worksheet, students must find the missing measurement in a variety of trapezoids. This excellent resource allows the students to check their answers, and to get "hints" should they run into difficulties. A terrific...

Young scholars explain the formula for finding the area of a paralellogram and its relation to the area of a rectangle. Finally, they construct the formula for the area of a paralellogram.

Students are given patterns of trapezoids and are to calculate the area of one trapezoid by using both patterns. They should form a parallelogram and calculate the area. They practice this technique until there is understanding.

Students identify diagrams of quadrilaterals and circles by different names and classify the figures. They name the areas for each diagram and practice solving the formulas for each.
