Ruler and Compass: Practical Geometric Constructions Andrew Sutton
Publisher: Walker & Company

What kinds of questions will fill the void survives in three standards: G-CO.12. Compass and straightedge construction is used to illustrate principles of plane geometry. Make formal geometric constructions with a variety of tools and methods (compass and straightedge, string, reflective devices, paper folding, dynamic geometric software, etc.). I choose Once you know and have intuitively internalized the principles, the computer allows you to magnify that knowledge in practical application immensely, but for the learning itself you need something much more tangible and direct, even if it is tedious and frustrating to do it that way. From the ancient Greek to the native Americans, peoples all over the world throughout time have produced geometric works of art. Geometric art has been around since antiquity. The version with the ideal angular constraints that is (Golden ratio and the 3-4-5 triangle) can also be easily drawn with a compass and straight-edge. Even New York State is giving up the ghost: when Common Core computer-based summative assessments replace Regents exams, there will no longer remain a practical test of the use of these mathematical tools. Argument B: There is no need for students to use a compass and straightedge, and all geometric constructions should be done using a drawing program. There may well have been a time when learning how to do geometric constructions with only a compass and straightedge was a valuable practical skill. 6th graders recently completed a unit exploring geometric design that incorporated practical use of the ruler and compass in the image-making process.
