Getting a Bead on It
Ferrucci, Beverly J.; McDougall, Jennifer; Carter, Jack
Mathematics Teaching in the Middle School, v15 n5 p268-273 Dec 2009
One challenge that middle school teachers commonly face is finding insightful, hands-on applications when teaching basic mathematical concepts. One concept that is a foundation of middle school mathematics is the notion of "linear functions." Although a variety of models can be used for linear equations, such as temperature conversions, atmospheric pressure and elevation, and so on, many do not lend themselves easily to classroom applications for students in the middle grades. This article presents a bead-stringing activity that provides a concrete way of showing linear equations, slopes, y-intercepts, and graphs for students enrolled in a traditional grade-8 mathematics class in a suburban middle school in New England. This hands-on activity gives students a concrete demonstration of the value of group work and also provides a way to solidify real-world connections to mathematics and review some recent content. (Contains 3 figures and 5 tables.)
