How much can different shapes hold? The answer varies depending on the shape and dimensions. Individuals learn the formulas for the volume of a sphere, cone, and cylinder. They apply the formulas to find the volume of these...

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...

Given measurement information on individual squares within a larger shape, scholars determine the total area of that square or rectangle. For one of these three problems they draw the shape knowing its total area and the measurements of...

Lead a discussion on the similarities between the properties of area and the properties of volume. Using upper and lower approximations, pupils arrive at the formula for the volume of a general cylinder. 

You don't need a scale to determine weight. This activity provides a way to use the concepts of air pressure and surface area to determine the weight of a vehicle by calculating the amount of weight each tire supports.

Learners solve and complete four various types of problems. First, they show on the diagram why the area of a triangle is given by a formula. Then, pupils find the area of each triangle and parallelogram illustrated, They also circle the...

Do your scholars have a basic understanding of area calculations? Give them an extra challenge with this irregular shape missing one of its length measurements. Using the given lengths, they figure the area of the entire shape. The...

In this calculating area worksheet, young scholars use their problem solving skills and the information provided to find the area of 6 rectangles.

Not all area word problems are straightforward. Here are some trickier ones to challenge your beginning geometers. They determine the area of two irregular shapes and one rectangle using given measurements. Remind scholars to use square...

For 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. 

For this FOIL method worksheet, students multiply binomials using the FOIL method and the area model.  Students find the area of rectangles to investigate why the FOIL method works.  Worked examples are provided.

Evaluate different aspects of geometry with one task. An assessment activity prompts learners to determine the area of a pathway in the shape of a parallelogram. The Pythagorean Theorem and area formulas for various polygons provide the...

Upper graders solve problems involving measurement of squares and rectangles to practice multiplication skills, finding area, and calculating prices and percentages. A performance assessment is included.

Elementary schoolers are arranged in pairs and view the video Math Works: Measurement: The Difference Between Perimeter and Area. They discuss any prior knowledge they have of the term perimeter and then brainstorm together what the...

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...

Investigate the area and perimeter of polygons in this geometry lesson plan. Young geometers use grid paper to draw a quadrilateral and calculate its area and perimeter. They also read The Greedy Triangle to identify the changing shape...

Learners find the area and perimeter of regular polygons and composite figures and examine the effect on the area and perimeter of a figure if the dimensions are multiplied by a constant. The nine page worksheet contains thirty-seven...

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.
