On Friday Feb 2nd, students do Dan Meyer’s Graduation activity. Their reasoning is to count time to pronounce names of 2, 3, 4 and 5 words and to count time between two graduates. Problems encountered: 1) missing people, 2) speakers omit words in names of 3+ words, 3) we have no time for seeing how much time speaker uses to pronounce names of 4 and 5 words [we use affine extrapolation for approximate it]. Final result: 12% of error of approximation #3-act #iteachmath
