You might be a “real” teacher if... • You grade papers in the car, during commercials, in faculty meetings, in the bathroom, and (at the end of the six weeks) have been seen grading in church. • You have a disjointed neck from writing on boards without turning your back on the class. • You are written up in medical journals for the size and elasticity of your kidneys and bladder. http://www.intermath-uga.gatech.edu/
You might be a “real” teacher if... • You have been timed gulping down a full lunch in 2 minutes, 18 seconds. Master teachers can eat faster than that. • You know it is better to seek forgiveness than to ask permission. • You buy Excedrin and Advil at Sam's. • You know secretaries and custodians run the school http://www.intermath-uga.gatech.edu/
You might be a “real” teacher if... • You hear the heartbeats of crisis; always have time to listen; know you teach students, not just a subject; and you are absolutely non-expendable. http://www.intermath-uga.gatech.edu/

Mathematicians have the unique talent of determining howfast they are running, and how much faster they need to runby the end of the race in order to set a personal record. http://www.intermath-uga.gatech.edu/

Learning over the Past 50 years Teaching Math in 1970: A logger exchanges a set "L" of lumber for a set "M" of money. The cardinality of set "M" is 100. Each element is worth one dollar. Make 100 dots representing the elements of the set "M". The set "C", the cost • About InterMath • What is InterMath? • Who is involved? • Rationale • Goals • Professional Development • Cognitive Development of production contains 20 fewer points than set "M". Represent the set "C" as a subset of set "M" and answer the following question: What is the cardinality of the set "P" of profits?

Learning over the Past 50 years Teaching Math in 2000: A company outsources all of its loggers. The company claims that contracting workers will Ultimately save them on expenses for benefits and salaries when demand for their product is down. The union requests that you take a closer look at historical employment, salary, benefits, and contracting data located on the web. Was outsourcing a good move?
