December 1, 2006:
Mr. Hart and Ms. Mola welcome my visit to their classroom by showing me
photos of their participation in the workshop at Lincoln Middle School
on November 2,


In the first lesson I observed, the 6th grade students were working on
making sense of probability. They were comparing theoretical
probability with the experimental data they were collecting by using a
spinner that can end up on a yellow, red, green or blue area. Which
color would come up most often if the spinner was set in motion 20
times? Since the circle is divided into 8 parts and 3 of the parts are
red, the students figured out that the probability of getting a red was
3/8 or 37.5%.


While Ms. Mola led the lesson, Mr. Hart helped individual students.

On my second visit, the 7th grade students were studying the triangle
inequality. After the students used straws to work on the problem, I
used a projection device to demonstrate this Geometer's Sketchpad
activity. (See fig. 1)

The 8th grade group worked
on the problem of finding out the dimensions
of a box that can be made from one sheet of paper that has the largest
volume. This is done but cutting out square corners to form a
rectangular solid. (See fig. 2)
