Eighth graders continue their geometry unit by focusing on volume. Using data, they create a spreadsheet, estimate and calculate volume. They solve real-life problems and round their answers to the hundredths place. They also practice...

Young scholars solve volume problems. In this geometry lesson, the class watches a video about clean water (link provided) and individuals compare the volume of different prisms, including an actual drinking glass. Extension activities...

Parallelograms are pairs of triangles all the way around. Pupils measure to determine the area and perimeter of a parallelogram. They then find the area of the tirangles formed by drawing a diagonal of the parallelogram and compare their...

In this surface area and volume instructional activity, students identify and complete each of 20 problems containing a different sized cube. First, they determine the surface area of each cube given the dimensions for height and/or...

With this interactive lesson, learners compute the surface area of rectangular prisms. They visit an online investigation applet and record data on the provided handout. Pair this lesson with the volume lesson by the same publisher as an...

You and your class will like this lesson on using visual models to relate the volume and surface area of solid shapes. Learners construct three-dimensional forms using nets. They calculate the surface area and volume for each and then...

Create a geometric playground. Pupils work through a performance task to demonstrate their ability to use geometric concepts to solve everyday problems. The accompanying engineering design lessons show teachers how the assessment works...

To take the longest path, go around—or was that go over? Class members measure scale drawings of a cylindrical vase to find the height and diameter. They calculate the actual height and circumference and determine which is larger.  

In this geometry activity, students walk through the process of comparing the scale factor of two cylinders' surface area and volume and answer questions about the scale factor of prisms. There are 15 questions.

Scholars first learn the definitions of the sine ratio, the cosine ratio, and the tangent ratio. After mastering these definitions, they use the new information to solve triangles.

Having a good working knowledge of math vocabulary is so important for learners as they progress through different levels of mathematical learning. Here is 125 pages worth of wonderfully constructed vocabulary and concept review cards....

In this rectangular prism activity, students find the volume and surface area of 3 rectangular prisms; answers are included on page 2.

In this surface area and volume learning exercise, students find each for a set of 6 triangular prisms. An answer key and web site reference for additional resources are given.

In this surface area and volume worksheet, middle schoolers find each for a set of 6 triangular prisms. An answer key is included on page 2.

Students differentiate triangular prisms from other prisms using nets. In this geometry lesson, students define the properties of a triangular prism and its symmetry. They build a triangular prism moving lines around.

Students calculate the volume and surface are of three-dimensional shapes. In this geometry lesson plan, students use the nets to prove their calculations of shapes. They identify the different parts of a solid using the nets.

This hands-on lesson takes young geometers on a tour of 2D polygons and 3D polyhedrons. After exploring different web resources and discussing geometric shapes, small groups construct models of polyhedrons using bendable straws. Note:...

Figure out the correct name for different three-dimensional shapes by watching the presentation on solid figures. Go through the main figures and read about the characteristics of each. Finish the topic with a multiple choice online...

Create and investigate nets for solid shapes with your class. They identify the different parts and faces of each polygon and solid then calculate the surface area and volume of cones. They use circle sectors of varying sizes to build...

In this geometry worksheet, students solve for the volume and area of given polygons. They find the surface area and identify the different parts of the polygon. There are 10 questions.

In this geometry worksheet, students solve word problems having to do with lines, angles, shapes, area, perimeter, and more. Students complete 57 problems total.

Name that shape! This simple worksheet has learners identify each geometric figure. They examine rectangular prisms, cylinders, rectangular pyramids, and hexagonal prisms. This one-page worksheet contains 8 problems, and the goals seems...

Boxing takes on a whole new meaning! The second installment of the three-part series has groups create lidless boxes from construction paper that can hold the most rice. After testing out their constructions, they build a new box....

This is how long we mow the lawn together. The assessment requires the class to work with combining ratios and proportional reasoning. Pupils determine the unit rate of mowers and calculate the time required to mow a lawn if they work...
