Given the measurements of three rectangular rooms, scholars determine the area of each. They are given units, so remind them to use square units in their answers. No side measurements exceed 20. Can your scholars measure the classroom...

Here is a straightforward example of how to apply the Pythagorean Theorem to find an unknown side-length of a trapezoid. Commentary gives additional information on proving that the inside of the trapezoid is a rectangle, but is...

These rectangles have everything scholars need to find the area, but none of them has units. Beginners to this skill multiply the length and width, all of which are whole numbers, to calculate and record the area for each. Consider...

Area is the amount of space that takes up the inside of a figure. To find the area of a rectangle, one must multiply the length by the width. Here, third graders are challenged to find the missing side length, given the area.

A triangle, square, hexagon, and circle all have a perimeter of one unit. Eighth graders must attempt to find the area of each and arrange them in order from least to greatest areas. A terrific task for applying four different...

Wrap up a instructional activity on surface area with a resource that asks scholars to use the idea of wrapping paper to investigate surface area. They draw representations of rectangular prisms on graph paper to find the areas of the...

In this middle school geometry worksheet, students determine the area of a rectangle.  The worksheet provides an explanations and example.  The one page worksheet contains three problems.  Solutions are provided. 

Find the area of triangles, rectangles, and parallelograms using this metric learning exercise.

Third graders find area by tiling a rectangle based on the given side lengths. This helps learners visualize and create the area of a figure. From here, they can count the total number of tiles inside the rectangle to find the answer.

What is the area? Because there is only one problem here (and it is followed by a detailed explanation) use this as an all-class warm up. Cover up the bottom half until scholars have shared their own answers. They examine a rectangle...

Intended for beginners to geometry, an area of a rectangle problem has scholars draw out the units within the shape. They segment it into four rows and six columns to determine how many squares the rectangle is made of and, eventually,...

What? The calculation of area is a linear distance? A short video shows how to use the areas of simple polygons to estimate the area under a graph. Pupils divide the area under a curve into figures to easier calculate the area. Given...

For this online math worksheet, students calculate the area of a variety of rectangles given the measure of their vertices. This excellent resource allows the students to check their answers, and to get "hints" should they run into...

Given a rectangle with specified dimensions, learners are prompted to create a new rectangle with the same perimeter, but a different area. This challenges third graders to think about perimeter and area in a new way. Each problem...

Given a rectangle with specified dimensions, third graders are prompted to create a new rectangle with the same area, but a different perimeter. This challenges learners to think about perimeter and area in a new way. Use...

By splitting a rectangle into equal parts, scholars can see area as well as calculate it. First, they determine the area of a rectangle given its side lengths. Then, they use the space provided to segment it into four equal parts,...

Scholars learn how to determine the area of compound shapes by finding the areas of the basic shapes that make it up. Pupils find the areas by adding areas together or subtracting them.

When does the Pythagorean Theorem come in handy? An intriguing video uses the Pythagorean Theorem to solve problems other than simply finding the length of a side of a right triangle. Pupils find the diagonal of a rectangle and the...

Each of these rectangles and squares has the length and width given with units. Can scholars solve for the area? Designed for beginners to this skill, all of these are whole-number single-digit measurements. There is a detailed example...

There's a trick to solving the area of a triangle, and it involves a skill your geometers have already mastered. Help them discover the connection between finding a rectangle's area and finding a right triangle's area as they solve for...

What if I can no longer justify area by counting squares? Lead a class discussion to find the area of a rectangular region with irrational side lengths. The class continues on with the idea of lower approximations and...

Scholars can use area formulas, but can they apply what they know about area? The lesson challenges learners to think logically while practicing finding area of shapes such as rectangles, circles, parallelograms, triangles, and other...

In this geometry activity, 6th graders find the area of four squares with given measurements. Students use metric units to calculate the area of each given square.

Geometry novices will enjoy this approach to finding area, as they aren't required to include units or a formula. The main objective here is to segment a rectangle into columns and rows to create squares, which then are used to find the...
