ALEX Lesson Plans Thinkfinity Lesson Plans Subject: MathematicsTitle: Adjustable Spinner      Add Bookmark Description: This student interactive, from Illuminations, allows students to create their own spinners and examine the outcomes given a specified number of spins. Students learn that experimental probabilities differ according to the characteristics of the model.Thinkfinity Partner: IlluminationsGrade Span: K,PreK,1,2,3,4,5,6,7,8,9,10,11,12Subject: MathematicsTitle: Birthday Paradox      Add Bookmark Description: This Illuminations lesson demonstrates the birthday paradox, using it as a springboard into a unit on probability. Students use the TI-83 graphing calculator to run a Monte Carlo simulation with the birthday paradox and engage in a graphical analysis of the birthday-problem function.Thinkfinity Partner: IlluminationsGrade Span: 6,7,8,9,10,11,12Subject: 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: 3,4,5,6,7,8Subject: MathematicsTitle: Sticks and Stones      Add Bookmark Description: In this Illuminations lesson, students play Sticks and Stones, a game based on the Apache game Throw Sticks, which was played at multi-nation celebrations. Students collect data, investigate the likelihood of various moves, and use basic ideas of expected value to determine the average number of turns needed to win a game.Thinkfinity Partner: IlluminationsGrade Span: 3,4,5,6,7,8Subject: Mathematics,ScienceTitle: Northwestern Crows      Add Bookmark Description: In this lesson, one of a multi-part unit from Illuminations, students use rational functions to investigate the feeding behavior of Northwestern Crows. Biologists have observed that northwestern crows consistently drop a type of mollusk called a whelk from a mean height of about 5 meters. Students investigate the relationship between the height of the drop and the number of drops by viewing a video clip; then, they plan a classroom experiment to model the dropping of whelks in order to collect and analyze data.Thinkfinity Partner: IlluminationsGrade Span: 9,10,11,12Subject: Mathematics,ScienceTitle: Conduct an Experiment      Add Bookmark Description: In this lesson, one of a multi-part unit from Illuminations, students use rational functions to investigate the feeding behavior of Northwestern Crows. Biologists have observed that northwestern crows consistently drop a type of mollusk called a whelk from a mean height of about 5 meters. Students investigate whether the crows minimize their work by dropping whelks as they do. The amount of work depends upon the height of the drop and the number of times the crow has to fly to this height. To answer the question, students explore the relationship between the height of the drop and the number of drops needed.Thinkfinity Partner: IlluminationsGrade Span: 9,10,11,12
