ALEX Lesson Plans
Subject: Mathematics (7), or Technology Education (6  8) Title: 2020  Year of the Cool School!
Description: Hey! Are you tired of your old lame school? Are the halls too narrow? Do you like walking outside to get to the cafeteria? Are the classrooms too small? Is the design too simple  just too wacky for a middle school? Well, now is the biggest break of your lives  You and your peers will design the school of the future and make history! Your biggest challenge is to create a section of a dream school that oozes and awes your peers. Each team will design a section (cafeteria, library, performing arts room, or recreational room) of the school, research different floor coverings for the section, research different loans to cover the cost of the floor coverings, and design a model of each section. Grab your math knowledge and as many construction tools as you can because you are about to construct a building for the world to remember. But wait, THE CATCH  your team will be competing against other groups. So put your thinking caps on and let the building begin!
Subject: Mathematics (7  12) Title: Is it a Triangle?
Description: The purpose of this lesson is to help students investigate the relationships of the lengths of the sides of a triangle in order to discover the three triangle inequality theorems. Students will learn how to draw valid conclusions from the information obtained from the activity and apply those conclusions to real world geometry problems. This serves as an introduction into more advanced geometric theorems. 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) Title: Trapezoids: What's Equal or Right About Them?
Description: This lesson will examine the properties of two trapezoids  isosceles and right. The lesson will then use the properties to solve deeper analytical problems.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.
