    July 20 - Wed
    • Classwork
    • What is geometry? Groups discuss and come back together.
    • Brief history of early geometry knowledge including the Babylonians, Egyptians, Greeks (Thales, Pythagoras, Plato, Euclid), Chinese, and Africans.
      Mention the Timeline for Geometry: Multicultural Highpoints from Geometry Activities from Many Cultures
      Skim LAV 6 section of the CD on Origins of Length, Area, and Volume Measurement
      Mention CD LAV 80 on Thales' Shadow Measurement Activity

      History of Euclid's elements including Euclid's 5th postulate (prop 29 and later).
    • Sum of the Angles in a Triangle: Write out Proposition 32 in modern language. Discuss Euclid's historical proof, paper folding, and then an Intro to Geometric Constructions via a construction in Sketchpad. Dr. Sarah models the construction. Discuss the history (attributed to Pythagoras), and compare and contrast the activities, discussing the benefits and difficulties with using them in various classes. Then the group goes to the computer lab to try the Sketchpad construction.
    • Pythagorean Theorem: Discuss the Yale tablet and Babylonian Pythagorean knowledge. Discuss the history of Euclid Book 1 Proposition 47 and of it's importance in measurement. Discuss Sketchpad demonstrations of the Pythagorean Theorem. From Sketchpad, under File/open, go to Desktop/205Math(yourcomputersnumber)/Applications(MacOS9)/Sketchpad/ Samples/Sketches/Geometry/Pythagoras.gsp Go through Behold Pythagoras! and Puzzled Pythagoras. Return to the classroom. Highlight the other proof from the video (Euclid's Pythagoras), and then Dr. Sarah's models the construction in Sketchpad.
      Mention CD activities LAV 124 Pythagorean Theorem, LAV 130 Practical Pythagorean Theorem, Geom 103 Pythagorean Project
      Hand out A Chinese Proof of the Theorem from Geometry Activities from Many Cultures in order to complement the Sketchpad Behold Pythagoras! activity Compare and contrast the methods used in the classroom.
