This morning, Erika had a math insight in the car. She said, "did you know that two tens are twenty?" I responded in the affirmative, so she went on to say, "and that three tens are thirty?"

She eventually got all the way to 100 with it, and also remarked, "if you count to twenty, it's like counting to ten twice!"

I have not tried to teach her this, though she has made use of an abacus, a chart going to 100, and Cuisenaire rods, all of which would encourage thinking about this kind of thing.

Go, Erika!
