A few days ago I had an amazingly successful lesson on sigma using sage interval notation and list comprehension.
I gave the kids a bunch of sigma expressions to evaluate. I told them I wasn't concerned about the final value so much as about their ability to translate these expressions into list comprehensions. So, for example, they had to come up with things like [n^2 - 5 for n in [0..10]]. The structure perfectly corresponds to sigma expressions. We weren't in a lab, but I had volunteers come up to enter their code in my computer that was being displayed. It worked like a charm. They really, really got it! One girl was obviously ecstatic. She said, "I never understood sigma before!
