ALEX Lesson Plans Subject: Arts Education (7 - 12), or Mathematics (9 - 12) Title: Graphing at all levels: It’s a beautiful thing! Description: This lesson addresses the societal issue of the arts being eliminated in many public schools be employing graphs (at any level) as an artistic media. Review of all types of graphs is included through various interactive websites.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 (8 - 12) Title: Quadrilaterals Description: This is an inquiry lesson used to review Algebra 1 objectives by applying them to geometry concepts. Students explore the properties of quadrilaterals and classify them by definition. This lesson can be use in geometry classes. Students in geometry classes can apply theorems and definitions of quadrilaterals rather than as an inquiry lesson.This lesson plan was created as a result of the Girls Engaged in Math and Science, GEMS Project funded by the Malone Family Foundation. Thinkfinity Lesson Plans Subject: MathematicsTitle: Supply and Demand      Add Bookmark Description: This Illuminations lesson focuses on having students create and solve a system of linear equations in a real-world setting. By solving the system, students find the equilibrium point for supply and demand. Students should be familiar with finding linear equations from two points or slope and y-intercept.Thinkfinity Partner: IlluminationsGrade Span: 9,10,11,12Subject: MathematicsTitle: Investigating Pick's Theorem      Add Bookmark Description: In this unit of three lessons, from Illuminations, students rediscover Pick's Theorem, which they were likely introduced to in middle school, and use algebra to determine the coefficients of the equation. They explore the concept of change as a mechanism for finding the coefficients of Pick's Theorem.Thinkfinity Partner: IlluminationsGrade Span: 9,10,11,12
