Subject: Mathematics (9  12) Title: Figure it out...
Description: This is an Internetbased (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 (9  12) Title: Surface Area of Pyramids and Cones
Description: In this inquirybased lesson, students will discover the formulas for the surface area of pyramids and cones.
This lesson plan was created by exemplary Alabama Math Teachers through the AMSTI project.
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 threedimensional shapes by creating a water tank comprised of these shapes. Students will work in groups of 45 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 45 students will take the information,pictures and 3D 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
Add Bookmark
Description: In this Illuminations lesson, students construct tetrahedrons and describe the linear, area and volume using nontraditional 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. Thinkfinity Partner: Illuminations Grade Span: 6,7,8,9,10,11,12
Subject: Mathematics Title: Are They Possible? Overhead

Description: This reproducible transparency, from an Illuminations lesson, depicts several isometric drawings of several '' impossible'' figures. Thinkfinity Partner: Illuminations Grade Span: 6,7,8
Subject: Mathematics Title: Using Cubes and Isometric Drawings
Add Bookmark
Description: In this unit of six lessons, from Illuminations, students explore polyhedra using different representations and perspectives for three dimensional block figures. In addition, students examine area and volume concepts for block figures within this context. Thinkfinity Partner: Illuminations Grade Span: 6,7,8
