Don's Math Room - 7 views

1. The table about which expectations are high, the students are all different, we study, ask questions, look for patterns, visualize the math, graph functions, read, play a game like Nim, or Conway's "The Game of Life" or "Racetrack", learn to learn, think about the math, look at a sunflower stalk, and do a problem different ways. Whereas some people have been known to "stand and deliver", a student once told Don he sits and listens-  and we have fun!

2. The 30-draw cabinet at the right in which the draws contain things like: old slide rules, old calculators, color cubes, Cuisenaire Rods, Pattern blocks, attribute blocks, people pieces, supplies (scissors, tape, tacks, stapler..), rubber bands for geoboards, wooden blocks of various shapes & sizes, 10x10 paper squares & 1x10 strips to multiply 12x13 in your head, measuring tools (rulers, hypsometer, angle measurer, map measurer, miras,..), guess my rule cards, tangrams, counters, rotograms,.. On top of this cabinet are cylindrical cans, bottles, a cone of string, shapes made out of white rods that where then doubled and tripled in each length to compare the volume ratios, blocks to make (A+B)3 ,.. The black file cabinet contains folders kept up to date by students who don't have a notebook. On top of the black cabinet is a globe and a bag of white cuisenaire rods (2000 of which were purchased from Learning Resources who imported them from China)- used by students to make patterns, and the 7 Soma pieces.

Why the Nautilus shell? Because it is beautiful and is a mathematical curve (spiral)!
