graphing-distance v time
Lesson Outline
This class was to reinforce the process of correct and specific graphing techniques. The story of the race between the tortoise an the hare was used as the basis of interpreting graphed material.
Graphs of distance vs time for a tortoise, moving with constant velocity, created a linear graph. From the graph the mathematical concept of slope was introduced as rise/run. The slope was introduced as being the speed between the 2 points picked. The average speed was also determined. The same type of graph was plotted for the movement of the Hare in the race. The Hare's graph was not linear but showed a time element of zero distance for a period of 4 minutes. The slopes of the different lines of this graph were determined along with the average speed. The reason for the loss of the race by the Hare became obvious when plotted.

Lesson Comments
Nicole worked very diligently and neatly on the graphs. She calculated the slopes of the lines and discussed their meaning. She does need some assistance with the actual math, but when shown what the numbers should be( she has a tendency to leave out a zero, like 60 rather than 600) is capable of arriving at the answer.
