In this basic shapes worksheet, students use formulas to determine the area of given figures. They compute the area of composite figures and subtract the area of shaded areas. This one-page worksheet contains 12 problems.

Painting an irregular figure can be tricky if we don't know the exact area. This interactive presentation reveals that irregular figures can be broken into smaller, simple figures that use the area formulas. Go through two examples,...

Not all structures take the shape of a polygon. The 21st lesson in a series of 29 shows young mathematicians they can create polygons out of composite shapes. Once they deconstruct the structures, they find the area of the composite figure.

You'd be surprised what you can do with a string! The constraint is the length of string, and the task is to maximize area. Given a series of composite shapes, learners must create a formula for the maximum area for a specified...

Third graders are exposed to finding the area of polygons by decomposing figures and recomposing them into rectangles. This strategy allows children to expand on their prior knowledge of constructing shapes by rearranging parts into...

Examine the surface area of composite figures using an exploratory approach. As a continuation of the previous lesson plan of the 29-part series, young scholars develop plans for finding the surface area of composite figures. Examples...

The area is essential to volume. As part of the review for the General Certificate of Secondary Education math assessment, a helpful video covers how to find the volume of several common 3-D figures. Pupils use the general volume formula...

In this composite figures worksheet, students solve twelve short answer problems. Students find the area of figures composed of various polygons given a sketch of the figure with side lengths labeled.

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...

For this geometry worksheet, students calculate the shaded area of given shapes.  They determine the area around a circle, a portion of a rectangle, and composite figures.  THis one-page worksheet contains two multi-step...

Go beyond the basic formulas and uncover the surface area and volume of 3-D shapes with this comprehensive and organized learning exercise packet. The problems include the basic formula computations while also challenging your learners...

What a fantastic resource! The class practices finding the area and perimeter of various regular and irregular shape by first counting the grid squares inside each shape, and then by using the traditional formula. The process is fully...

Eighth graders are shown a blueprint of a house and must determine the amount of carpet needed. In groups, they calculate the area of rectangles and triangles and apply them to the shapes in the blueprint. To end the lesson, they...

Designing a deck sure demands a lot of math. Future engineers and architects learn about the areas and perimeters of squares, rectangles, triangles, and composite figures. They apply their new knowledge to design a deck with a specified...

In this composite figures worksheet, high schoolers solve 11 short answer problems. Students find the area of figures composed of various polygons. High schoolers find the area of each figure given a sketch of the figure with various...

Students calculate the volume and surface area of each shape. In this geometry lesson, students use nets and other three dimensional polygons to create visuals of the volume of a shape. They define important vocabulary words...

Develop a strategy for finding the area and perimeter of irregular figures. Building on an understanding of finding area and perimeter of rectangles and triangles, learners apply the same concepts to composite figures. After...

With minimal setup and maximum freedom, young geometers are encouraged to think outside the box on a seemingly simple application problem. Though the task seems simple, measuring a given paper clip and finding how many 10 meters can...

Learners are designing a stunning new water feature for an aquarium, but they soon discover that more than just a pretty home for their fishy friends is required.  From calculating the volume of a composite shape through the...

Students measure the perimeter and area of their polygons. In this geometry activity, students calculate the volume and area using the correct tools. They calculate the time and temperature and the perimeter and side lengths of triangles.

For this circle worksheet, students find the area and circumference of circles and compare their size using percents. Students determine the are of composite figures made of circles and rectangles. This one-page worksheet contains six...

Make the strongest beam possible using taffy? Groups mold a taffy-water mixture into a beam and a reinforcing material of their choice. To finish the final installment of a two-part series, participants test its strength by adding...

Tenth graders predict the shape of a geometric figure in 3D. In this geometry lesson, 10th graders construct 3D shapes to perfect their knowledge of measuring and predicting. This assignment is also available as an online interactive...
