Developing a Sense of Scale

This lesson unit is intended to help you assess whether students recognize relationships of direct proportion and how well they solve problems that involve proportional reasoning. In particular, it is intended to help you identify those students who: use inappropriate additive strategies in scaling problems, which have a multiplicative structure; rely on piecemeal and inefficient strategies such as doubling, halving, and decomposition, and have not developed a single multiplier strategy for solving proportionality problems; and see multiplication as making numbers bigger, and division as making numbers smaller.

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.

An interactive applet and associated web page that demonstrate the congruence of polygons. The applet presents nine polygons that are in fact congruent, but don't look it because they are reflected and rotated in various ways. If you click on one, it rotates and flips as needed, then slides over the top of another to show it is congruent. The web page describes how to determine if two polygons are congruent. Applet can be enlarged to full screen size for use with a classroom projector.

This task lets students explore the differences between linear and non-linear functions. By contrasting the two, it reinforces properties of linear functions. The task lends itself to an extended discussion comparing the differences that students have found and relating them back to the equation and the graph of the two functions.

An interactive applet and associated web page that provide step-by-step instructions on how to find the center of a circle using only a compass and straightedge. The method used involves constructing the perpendicular bisectors of two random chords. The bisectors intersect at the center of the circle. The animation can be run either continuously like a video, or single stepped to allow classroom discussion and thought between steps. Applet can be enlarged to full screen size for use with a classroom projector.

Going around in circles!: around and about a geometric figure

Geometry can be an exercise arena for strengthening those logic muscles that middle school students need to flex. When we work with a geometric figure—a circle, for instance—and apply the ancient tools of compass and straightedge, geometry can become a rich ground for developing design. And a circle has size, so a unit on this topic necessarily brings in the mathematics of its measurement. Circles, then, is a geometric topic that can provide mental challenge, opportunity for artistic development, and connections to both the history of measurement and its everyday applications.
For this unit we have selected online activities that will enable your students to look at circles from these various viewpoints. The activities range from measurement to theorems about the circle to art and symmetry. Many will engage students in solving problems or in creating designs. Others will allow them to investigate the thinking behind the area and circumference formulas, either through virtual simulations or hands-on projects. We hope these activities will add to your repertoire of ways to present the "many-sided" topic of circles.
