New ReviewNot all prisms are cubes. A short video introduces the definition of a prism and uses that definition to create a general volume formula. Worksheets provide pupils several opportunities to practice finding the volume of a wide variety of...

New ReviewTurn up the volume. After identifying the three dimensions of a prism, the presenter gives the formula for finding its volume. Using the formula, the video shows pupils how to find the volume of a rectangular prism and a cube. Classmates...

New ReviewCalculate one hypotenuse then repeat. The resource provides a variety of ways for finding the length of the diagonal in a prism. Using the Pythagorean Theorem, pupils find a variety of distances in 3-D figures. The distances range from...

Quick, name that shape! Scholars learn the names and common properties of three-dimensional solids. They watch a short video that shows an example of each shape and identifies the two-dimensional faces that make up its surfaces.

Ready to learn a voluminous amount about volumes? Look no further! Learners view an informative YouTube video that shows how to calculate the volume of rectangular prisms with fractional side lengths. It goes on to explain the process of...

Don't let your classes get stuck on area calculations—grab their attention with an inquiry-based lesson! Scholars must develop a plan to determine how may sticky notes it takes to cover the surface of a door. They decide on the...

If cubes have the smallest surface area, why aren't there more cube-shaped packages? Scholars take a box in the shape of a rectangular prism, cut it up, and make new boxes in the shape of cubes with the same volume. They then brainstorm...

Build foundational knowledge of volume by building boxes. Given dimensions for a piece of grid paper, young mathematicians determine the number of possible open-top boxes it will make. As part of this task, they also find the box with...

Set the bases of a conversation on prisms. The segment of a playlist on geometry introduces prisms and their parts. After visualizing prisms, the video discusses how to find the surface area and volume of prisms.

Slice up solids. A portion of a geometry playlist introduces two conventional ways to visualize 3-D figures in 2-D. The resource defines cross-sections and nets and provides examples of both.

Does the shape of a hay bale affect profits? A practical instructional activity asks scholars to calculate the volume of both square and round bales of hay. They compare their results with hay prices to determine value.

Using a Venn diagram, learners write the attributes that the two solids—rectangular prism and triangular prism—have in common where the circles intersect and the attributes that they do not have in common in each individual circle.

You've covered areas and volumes, now it's time for surface areas. A series of four lessons compare ratios of similar figures from two to three-dimensional calculations. The final lesson of the series investigates the ratios of surface...

Help learners advance to three-dimensional figures. An applet allows them to examine similarity of these figures. They compare ratios of the dimensions as well as ratios of their volumes.

Two activities for the price of one. Young mathematicians take part in two activities. The first requires the use of spatial reasoning to order a set of pictures based on landmarks on a map. The second has learners answer some questions...

Why do we pack foods in cylindrical cans and then pack them into boxes with wasted space? Scholars explore the relationship of volume in cylinders and the volume of rectangular prisms. Then they create rectangular prisms with similar...

How can you better explain the standards? A collection of resources gives teachers the resources needed to teach topics within the eighth grade curriculum. Lessons provide engaging activities to use within the classroom. 

Turn up the volume in 3-D. The video introduces the concept of volume and the units used to measure it. Using a graphical representation of translating 2-D figures, the resource develops the formulas for finding the volume of prisms and...

Take a look at a prism after slicing and dicing it. Given a rectangular prism with all three dimensions, pupils draw the horizontal and vertical cross-sections and provide their dimensions. They also determine the dimensions of a...

Here's a package deal for a task creating equations for packages. An extended problem has learners creating a cubic function to represent the volume of a box. They consider constraints and interpret key features of their functions.

There's nothing fishy about this resource. Individuals use unit cubes to build a model of an aquarium in the shape of a rectangular prism that meets given criteria. Consideration of both volume and surface is necessary. 

Cast a net over the formulas for surface area. Pupils use nets to develop surface area formulas in the 19th segment in a 22-part series. They first see the patterns of similar calculations in finding the area of the faces of rectangular...

Figure out what it will take to cover up. The 18th part of a 22-part series presents nets as a way to determine surface area. Pupils determine the measurements of the portions of the nets before calculating the area of each portion and...

There's no need to think outside the box for this one! Scholars measure the length, width, and height of various boxes. Results help develop the formulas for the surface area and volume of rectangular prisms.
