What is subitizing anyway?
And more importantly....how do I say that word???
SUBITIZING is the ability to quickly identify the number of items n a small set without counting.
It is pronounced "SUE"bitize....not "SUB"itize. I made this mistake in a fairly large math meeting. I didn't feel too bad though because no one else knew how to say it or what it was either!
Think about dice. My grandmother was a brilliant Yahtzee player. She could add up those dice before they had even hit the table. She had excellent subitizing skills! When you roll a "6" and you know it's six just by the pattern on the dice that's subitizing. We have been doing this our whole lives we just didn't know there was a name for it. (Well at least I didn't!)
This week we introduced the Subitize song from HeidiSongs. The kids loved it and even better they now know the name that goes along with this skill! I've been teaching number recognition with dot cards since WAY back when....we called them Quick Images in our old math program. This song hit home for the kiddos with this skill and they REQUEST it every day. Here is a little video....
