Subject: Mathematics (9 - 12)
Title: Figure it out...
Description: This is an Internet-based (online) and group discussion lesson. Students will learn the formulas for surface area and volume of cylinders and cones. Students should have previously learned how to determine the area for a circle; however, this lesson will review that particular process.

Subject: Mathematics (7 - 12), or Technology Education (9 - 12)
Title: Water Tank Creations Part I
Description: In this lesson students will study the surface area and volume of three-dimensional shapes by creating a water tank comprised of these shapes. Students will work in groups of 4-5 to research water tanks, develop scale drawings and build a scale model. Teacher will evaluate the project using a rubric and students will assess one anothers cooperative skills using a rubric.

Subject: Mathematics (7 - 12), or Technology Education (9 - 12)
Title: Creating a Water Tank - Part II "Selling the Tank"
Description: Working in groups of 4-5 students will take the information,pictures and 3-D model of the water tank they assembled in Part I of Creating a Water Tank and develop a web page and a video presentation. The web page will be a tool to advertise their water tank construction company and must include hyperlinks and digital pictures. The video presentation will be a "sales pitch" to a city council. The web page and video will be scored using a rubric. The web page and video must include the surface area, volume and cost of construction.

Subject: Mathematics
Title: Tetrahedral Kites     
Description: In this Illuminations lesson, students construct tetrahedrons and describe the linear, area and volume using non-traditional units of measure. They combine four tetrahedra to form a similar tetrahedron whose linear dimensions are twice the original tetrahedron. The area and volume relationships between the first and second tetrahedra are explored, and generalizations for the relationships are developed. In addition, there is a link to an assessment activity sheet.

Fishing for the Best Prism
http://illuminations...
In this lesson, students use polydrons to create nets of rectangular prisms. They discover that there are many configurations for rectangular prisms with the same volume, and determine that certain configurations minimize surface area. The lesson continues in a discovery activity related to building the most cost-efficient and appealing fish tank.
