This is a college level math session for elementary and middle-school teachers. ... More

This is a college level math session for elementary and middle-school teachers. In this session, we'll look at several topics related to fractions, percents, and ratios. As in earlier sessions, we'll look at graphical and geometric representations of these topics, as well as some of their applications in the physical world. As you work through the activities in this session, reflect on how mathematics is reasonable and logical, and how it is helpful to look for the logical patterns that emerge when you think about a mathematical situation.

Students will work together in small groups of four to six students to solve the following word problems. Their solutions will require them to practice interview techniques and create a database and/or spreadsheet of their results. This information will be the basis of the answers to the following eight word problems. Skills such as area, cost, calorie count, ratio, percentage and scale, as well as persuasive writing will be applied. Less

Task Description: This task asks students to recognize geometric patterns, visualize and extend the pattern, generate a non-linear sequence, develop and algebraic generalization that models the growth of a quadratic function and verify the inverse relationship of the quadratic relationship. The Aussie Fir Tree task is a culminating task for a 2-3 week unit on algebra that uses the investigation of growing patterns as a vehicle to teach students to visualize, identify and describe real world mathematical relationships. Students who demonstrate mastery of the unit are able to solve the Aussie Fir Tree task in one class period. Less

100,000,000 Guinea Pigs : The Dangers of Consumption

In 1927, responding to the seemingly overpowering claims of advertisers and mass marketers, engineer Frederick Schlink and economist Stuart Chase published Your Money's Worth, which argued for an "extension of the principle of buying goods according to impartial scientific tests rather than according to the fanfare and triumphs of higher salesmanship." Your Money's Worth became an instant best-seller, and the authors organized Consumers' Research, a testing bureau that provided information and published product tests in a new magazine, Consumers' Research Bulletin. The 1929 stock market crash heightened suspicion of consumer capitalism, and the magazine had 42,000 subscribers by 1932. In 1933, Schlink and Arthur Kallet (executive secretary of Consumers' Research) published 100,000,000 Guinea Pigs: Dangers in Everyday Foods, Drugs, and Cosmetics. The book struck a responsive chord in depression-era America--it went through thirteen printings in its first six months and became one of the best-selling books of the decade. The book's first chapter ("The Great American Guinea Pig"), gave a flavor of their vigorous arguments. Less

Seventh grade students have had wide-ranging experiences with fractions and operations on fractions, but ratios and rates may be new concepts for them. This activity introduces students to the idea of rates via a familiar and tangible product: Kool-Aid. Students will add varying amounts of Kool-Aid powder to a set amount of water, thereby producing a sensory experience of rates. The Kool-Aid example also provides a base experience upon which other examples can build. Less
