ALEX Lesson Plans 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. Thinkfinity Lesson Plans Subject: MathematicsTitle: Boxing Up      Add Bookmark Description: In this lesson, from Illuminations, students explore the relationship between theoretical and experimental probabilities. They use an interactive box model that allows them to simulate standard probability experiments such as flipping a coin or rolling a die.Thinkfinity Partner: IlluminationsGrade Span: 6,7,8Subject: MathematicsTitle: Stick or Switch?      Add Bookmark Description: This lesson, from Illuminations, presents a version of a classic game-show scenario. You pick one of three doors in hopes of winning the prize. The host opens one of the two remaining doors, which reveals no prize, and then asks if you wish to stick or switch. Which choice gives you the best chance to win? Students explore different approaches to this problem including guesses, experiments, computer simulations, and theoretical models.Thinkfinity Partner: IlluminationsGrade Span: 6,7,8,9,10,11,12Subject: MathematicsTitle: Sticks and Stones Demo      Add Bookmark Description: This student interactive, from an Illuminations lesson, allows students to generate random throws for the game '' Sticks and Stones.'' In the game, three sticks are tossed and a player moves his or her marker according to how the sticks land.Thinkfinity Partner: IlluminationsGrade Span: 3,4,5,6,7,8
