The construction of the perpendicular bisector of a line segment is one of the most common in plane geometry and it is undertaken here. In addition to giving students a chance to work with straightedge and compass, the problem uses triangle congruence both to show that the constructed line is perpendicular to AB and to show that it bisects AB.

This task is for instruction purposes. Part (b) is subtle and the solution presented here uses a "dynamic" view of triangles with two side lengths fixed. This helps pave the way toward what students will see later in trigonometry but some guidance will likely be needed in order to get students started on this path.

An interactive applet and associated web page that provide step-by-step instructions on …
An interactive applet and associated web page that provide step-by-step instructions on how to divide a line segment into any number of equal parts, using only a compass and straightedge. The applet starts with a given line segment and ends with that segment divided into n parts. In the applet n=5, but the construction works for any n. The animation can be run either continuously like a video, or single stepped to allow classroom discussion and thought between steps. The text on the page has printable step-by-step instructions. Applet can be enlarged to full screen size for use with a classroom projector.

In these lessons students will explore the paintings of Horace Pippin and Wayne Thiebaud and the mobiles of Alexander Calder to discover and practice math and visual art concepts. Background and biographical information about the work of art and artist, guided looking with class discussion, and activities with worksheets using mathematical formulas and studio art provide the framework for each lesson.

The project objective is to have students make a realistic 3-D model that is to scale. Student Mission: Your objective is to create a 3-D model of a building of your choice or imagination. The building must be to scale relative to an average-sized person. You make recreate a dwelling, barn or famous building OR create your dream home. Your building must be to scale and should be finished (windows, roof, shutters, steps, furniture, etc.). The outside of your building should include some surrounding features (e.g. bushes, trees, sidewalks, street, shed, etc.). Your final project should incorporate the elements listed on the rubric and be as detailed as possible. Be creative!
