We continued the "Girl Scout Cookie Box" problem from last class and found around 900 boxes would fit in the cargo space of the SUV. We looked at the nature of 3-act math tasks and the math class core beliefs. Went through the syllabus in detail, and passed out the reading assignment on math as an art.

Warm up dealt with finding the slope and intercepts (both x and y) of a linear function in standard form. (see here for slopes, see here for intercepts). Also got textbooks today and wrote our names in them. Wondered about what geometry is/means and some history of Euclid, the 5 axioms, and the 3 undefined terms of geometry of Point, Line, and Plane. Made graphic organizers of each including examples, notations, and some descriptions. Also made a foldable dealing with the relationships that occur among planes and lines. Closed with starting off the "Sketch Artist" game where one person must use words to describe a geometric diagram to their partner who can't see the diagram and must draw it from the description. We will continue the game next class.

Warm up was a written response to a passage from "A Mathematician's Lament" (4A did an area problem). Went over homework, then continued playing the "sketch artist" game with our face partners. Summarized learning from it, then looked at a dancer in motion and observed various angles made by his body. Developed definitions for line segment, ray, and angle from points/lines/planes and used clickers to show our knowledge of naming various figures. Then did our first construction, an equilateral triangle which we turned into a Reuleaux Triangle.
