An interactive applet and associated web page that demonstrate the bisector of an angle. An angle is shown using two line segments that can be dragged to change the angle measure. The angle is bisected by a line which moves while dragging to always divide the angle into two equal angles. The angle measures can be turned off for class discussions. Applet can be enlarged to full screen size for use with a classroom projector.

# Camp Earth Bound: Problem Solving and Finding for Fun

Students will work together in small groups of four to six students ... (more)

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)

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.

# Congruent Polygons

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.

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

Geometry can be an exercise arena for strengthening those logic muscles that ... (more)

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. (less)

# Boxed In and Wrapped Up

Students find the volume and surface area of a rectangular box (e.g., ... (more)

Students find the volume and surface area of a rectangular box (e.g., a cereal box), and then figure out how to convert that box into a new, cubical box having the same volume as the original. As they construct the new, cube-shaped box from the original box material, students discover that the cubical box has less surface area than the original, and thus, a cube is a more efficient way to package things. Students then consider why consumer goods generally aren't packaged in cube-shaped boxes, even though they would require less material to produce and ultimately, less waste to discard. To display their findings, each student designs and constructs a mobile that contains a duplicate of his or her original box, the new cube-shaped box of the same volume, the scraps that are left over from the original box, and pertinent calculations of the volumes and surface areas involved. The activities involved provide valuable experience in problem solving with spatial-visual relationships. (less)
