*got*to get them sorted out before the next Math in Your Feet Family Night! Do you think you could help me?

Kid: How should we start?

Me: I've set out four bags, one for each set of rods. We need to divide up the rods equally so there is one full set in each bag.

Kid: "Twenty one."

Me: "How many orange rods go in each pile?"

Kid: (Starting with four in each group, then adding one more to each, one remains.)

Me: So, five in each group, with a remainder of one?

Kid: Look, Mama. Four times five is twenty. I knew that.

Yeah, I know. I know that addition, subtraction, multiplication and division are steadily working their way into her consciousness and her skill bank, and all of this primarily by delving deeply into doubles, halves and evens. I'm not kidding when I say that doubles/halves/even-ness comes up practically every day, one way or another. I think it's a great way for a six year old to explore and learn about numbers, geometry, and the meaning of math. There's actually something quite comforting in our daily discoveries of balance and symmetry whether in number play, through observations of our physical environment, or in the things we create with our own hands (the attributes matching game, for example, or our recent exploration of circles).

I also know this kind of sorting activity is pretty basic, but having lots and lots of experience with operations in as many different contexts as possible is

*always*useful. In this case it was extra useful 'cause I didn't have to do this chore myself and I was able to work in some math inquiry -- sorting, classifying, measurement, division*and*a chance to get reacquainted with the rods -- all at the same time!
