Do not count the ducks

Via Joanne Jacobs I find out that the state of Illinois now has 172 learning goals for kindergarten. One of them, under “Mathematics”, is “Estimate numbers of objects in a set”. This is particularly amusing to me because back when I was a young punk, I spent a lot of time on the PLATO educational computer system at UIUC. One of the lessons that achieved internal notoriety was about exactly that subject, estimating the cardinality of sets. It used ducks, leading to a catch phrase “do **not** count the ducks!”. I still laugh, but you had to be there.

P.S. I should probably read through the list because Boy Two is starting kindergarten in Illinois this year.
