What a class I had this morning.
Someone stole my teacher's textbook for class (which is a teacher's edition and he had all of his notes, etc in it). By the time they finally fessed up and gave it back, we already wasted 20 minutes of class. Then he taught us two new things and that took 30 minutes.
Then is when all you know what broke loose. Before we could leave for the day, he asked us to turn in the back of the textbook where there was a chart. The left column was filled with numbers 1-10, and the top row was filled with numbers .0-.9 So basically, say you had the number 6.3. You'd go to the left column, find your 6, then go to the top row and find your .3. Then you'd use your fingers and scroll across and down and meet together somewhere on the chart to get the new number.
I probably didn't explain it well enough, but it was finding two numbers that you already have in front of you to get a statistic. Prior to doing this, our teacher told us that it would take 2 minutes. I'm sure he was just as shocked as I was that it took 40 minutes. I was in such a bad mood after class. We were supposed to get out early since it was a review day, but we stayed longer than ever.
Needless to say, I have a major headache!
