#### Confetti Task

Using the net of a can, learners develop formulas for the surface area and volume of a cylinder. They then apply their formulas to solve problems about a cylindrical container used to disperse confetti.

Lesson Planet

#### Coal Silo Design Task

The coal is mined. Now what? Scholars design a coal silo that stores mined earth using at least two different three-dimensional shapes. They calculate the volume, determine the amount of mined earth produced in a day, and find the amount...

Lesson Planet

#### Exploring Coal Pillar Mining

Coal mines can be a gold mine of math applications. After reading some basic information on coal mining, learners draw blueprints of a coal pillar in the shape of a composite figure. They find the volume of material from the coal pillar...

Lesson Planet

#### Lemonade Business - Investigating Surface Area and Volume of Containers

Boost lemonade sales by using the perfect container. For a given volume, future entrepreneurs design a container that will have the least surface area and by extension, the least cost of material. They create a two-dimensional net of...

Lesson Planet

#### Swimming Pool Dilemma

Different shape, same volume—that's quite a challenge! Scholars design a pool for an imaginary client using three-dimensional figures. They must then create a second pool for another client with the same volume, but using different shapes.

Lesson Planet

#### Build-a-Toy

Don't toy with using a fun lesson. Scholars design new toys and then create scale drawings. They determine the volume and surface area of the toys, and then research prices of raw materials to estimate the manufacturing costs.

Lesson Planet

#### Green Acres is the Place to Be!

Nurture a love of math and farming at the same time. Pupils apply geometry concepts, such as surface area and volume of three-dimensional shapes and similarity ratios, to farming contexts. They consider the dimensions of bales of hay,...

Lesson Planet

#### Surface Area and Volume

Who knew there were pyramids in China? Learners apply surface area and volume formulas to several different real-world situations. They calculate the volume and surface area of an aquarium, an ice cream cone, and Egyptian and Chinese...

Lesson Planet

#### Fun with Solids

Unlike a volcano, the lesson won't blow up in your face. Young mathematicians use dried beans to discover the relationship between the volumes of cones and cylinders and to write a formula for the volume of a cone. They then research...

Lesson Planet

#### Surface Area and Volume of 3-D Objects

Don't let the class tank the project. After reviewing formulas for surface area and volume, pupils design fish tanks that maximize volume. They research cost of materials online and must meet a budgetary constraint when creating their...

Lesson Planet

#### Fun with Solids

Cakes offer a yummy way to learn about math. Scholars use manipulatives to discover the formulas for the surface area and volume of prisms and cylinders. They use their formulas to calculate the amount of cake mix and frosting necessary...

Lesson Planet

#### Fun with Solids

Geometry is all around us—if we're only willing to look. The final three activities of the Fun with Solids unit continue work on surface area and volume. For lesson three, scholars investigate the formulas for spheres and solve a problem...

Lesson Planet

#### Building Your Own Home

Building a home means mastering math. Scholars apply various math topics to situations associated with the construction of a home. They consider the volume of concrete needed for a foundation, the perimeter and area of
blueprints, the...

Lesson Planet

#### 2 and 3 Dimensional Shapes

Take a similar approach to three dimensions. Pupils develop the relationship between areas of similar objects and see how they relate to the ratio of the sides. Building upon area formulas, small groups put together volume formulas for...

Lesson Planet

#### Next Top Model

Create a world of similar models. The geometry and measurement unit uses real-world scenarios to create models of familiar buildings and rooms. Scholars work with blueprints and scale models to compare areas and volumes between the...

Lesson Planet

#### 2D and 3D Geometric Shapes

Mathematicians examine everyday objects around the classroom to categorize them as two or three-dimensional. Following a group discussion, pairs work collaboratively to identify objects. Independently, scholars complete a practice page.

Lesson Planet

#### Whole Number Exponents: Teddy Bear Box

Five questions—multiple-choice, fill in the blank, and discussion—make up an interactive that challenges scholars to mail a teddy bear using the smallest box possible without squishing it. A box with movable sides allows mathematicians...

Lesson Planet

#### What is a Constellation

Why do some stars in a constellation appear brighter than others? Using a get-up-and-move astronomy activity, scholars explore perspective and the appearance of constellations in the sky while developing an understanding of the...

Lesson Planet

#### Accessible Shapes

All the 2-D and 3-D measurement work you need is in one location. Divided into three sections, the geometry lesson plans consist of visualization of three dimensions, classifying geometric figures, and finding surface area and volume....

Lesson Planet

#### Explore 3D Design

Explore the creativity of your pupils in a design challenge! Learners use a two-dimensional image as inspiration to design a three-dimensional object that has a practical use. Their designs are specific to assigned professions, and they...

Lesson Planet

#### Smarter Balanced Sample Items: 7th Grade Math – Target E

How well do your classes understand scale? You'll certainly know after they answer the set of eight questions from an informative and helpful presentation. Questions include items from coordinate geometry, similar triangles, and scale...

Lesson Planet

#### Views and Elevations

The view depends upon location. A short video introduces the idea of views and elevations of 3-D figures. Using figures composed of cubes, the presenter creates their front, side, and plan views. The last figure requires the viewer to...

Lesson Planet

#### 3D Pythagoras

Calculate 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...
