ALEX Lesson Plans
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 (9  12) Title: Pennies, Pennies and More Pennies
Description: Students will work in cooperative groups to determine the number of pennies to line the baseboard, cover the floor and fill the room. Students will determine the geometric probability that the head of pin will land on the penny and not the floor space between pennies.This lesson plan was created as a result of the Girls Engaged in Math and Science, GEMS Project funded by the Malone Family Foundation.
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: Soda Cans
Add Bookmark
Description: This reproducible activity sheet, from an Illuminations lesson, guides students through a simulation in which they try different arrangements to make the most efficient use of space and thus pack the most soda cans into a rectangular packing box.

Subject: Mathematics Title: Are They Possible? Overhead
Add Bookmark
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: Building Using the FrontRightTop View
Add Bookmark
Description: In this lesson, one of a multipart unit from Illuminations, students explore drawing the frontrighttop view when given a three dimensional figure built from cubes. Students also explore building a three dimensional figure when given the frontrighttop view. Thinkfinity Partner: Illuminations Grade Span: 6,7,8
Subject: Mathematics Title: Circle Packing
Add Bookmark
Description: In this unit of three Illuminations lessons, students explore circles. In the first lesson students apply the concepts of area and circumference to explore arrangements for soda cans that lead to a more efficient package. In the second lesson they then experiment with threedimensional arrangements to discover the effect of gravity on the arrangement of soda cans. The final lesson allows students to examine the more advanced mathematical concept of curvature. There are also links to online interactives that are used in the lessons.

Subject: Mathematics Title: Circle Packing and Curvature
Add Bookmark
Description: In this lesson, one of a threepart unit from Illuminations, students investigate the curvature of circles. Students apply definitions and theorems regarding curvature to solve circle problems. In addition, there are links to an online activity sheet and other related resources.

Subject: Mathematics Title: Do They Match? Overhead
Add Bookmark
Description: This reproducible transparency, from an Illuminations lesson, depicts several pairs of isometric drawings of threedimensional figures. Students determine whether the drawings in each pair represent the same shape as one another. Thinkfinity Partner: Illuminations Grade Span: 6,7,8
Subject: Mathematics Title: Flowing Through Mathematics
Add Bookmark
Description: This student interactive, from Illuminations, simulates water flowing from a tube through a hole in the bottom. The diameter of the hole can be adjusted and data can be gathered for the height or volume of water in the tube at any time. Thinkfinity Partner: Illuminations Grade Span: 9,10,11,12
