I am disappointed that Texas Instruments can't be as efficient with this website and that the company no longer sponsors activity write-ups as for the first 3 seasons. Just by looking at the Wolfram site I can see possibilities for new lessons. Even the blogs on this site are posted later than the updates to the Wolfram site. As a full time math teacher I do not have time to turn these blog comments into full lesson activities and I thought the previously posted WAUMED activities was a good way to show how TI calculators enhance mathematics instruction. I think it is in the company's interest to once again pay teachers to develop new lessons for the season 4 of Numb3rs as there are still other brands of graphing calculators on the market.

If I sign 5 signatures during each of the first three minutes, but only 4 signatures during the fourth and fifth minutes b/c of fatigue, how many signatures will I be able to sign during the 100th minute? A linear model would give a negative answer, so kids will have to use a different model.
