If someone asked you to draw a regular hexagon, how would you do it? Ancient Greek geometers had only a compass (the kind that draws circles, not the kind that you use when you read a map!) and a straightedge (think of a ruler without any markings on it) available to them. Using these simple tools and some geometric knowledge, it is possible to create many accurate angles, shapes and other geometric features. Depending on student interest and prior knowledge, students will learn some or all of the following: *How to duplicate line segments and angles *How to bisect (split in half) line segments and angles *How to create a sets of parallel and perpendicular lines *How to construct an equilateral triangle, a rectangle, a rhombus and a regular hexagon. *How to construct the center of gravity of any triangle so that it can be balanced on the tip of your pencil This lesson is useful for students who need more hands-on instruction in their high school geometry course, but the methods learned in this lesson can also be applied to art and design. Armed with these techniques, what will you do next? Build a birdhouse? Create some abstract art?

Students will need: blank white paper at least one sheet of light-colored cardstock scissors a ruler (or other straightedge) a sharp pencil a high-quality* geometric compass *In my experience, plastic compasses do not last as long and are more likely to loosen, bend, or break over time -- even a short period of time! I recommend a metal compass with an adjustment wheel in the center. Brands Blick and Staedtler make compasses like this for about $9.

Experiencia y certificaciones del docente
Geometry is one of my favorite subjects to teach. I find geometric construction to be very satisfying and fun. Learning the basics opens a whole world for learners to create and grow! Reseñas
