OK, so I know it’s a little mean but I just can’t help myself sometimes. Today as a warm-up I asked my geometry classes what zero divided by zero was. A lively debate ensued, with students making arguments for 0, 1, undefined, infinity, and “new stuff” which meant something they didn’t know about yet. I got them all ready to hear the answer, and I said, “The answer to zero divided by zero IS…something we’ll talk about on Monday.” Both classes sent up a roar of frustration and started moaning and groaning. I couldn’t help but laugh. I crack myself up sometimes.
