I helped them mix a batch of sugar cookie dough, adding cocoa to half the batch, and rolling it out, so they could cut two of each shape, out of the vanilla, and two out of the chocolate dough.
Then, they cut one set of each of the shapes symmetrically, and one set asymmetrically, and mixed up the chocolate and vanilla pieces.
After the cookies were baked, and cooled, as the children ate their snack, I challenged them to tell me which cookie, on their plates, had the chocolate, and vanilla, that were basically symmetrical in shape, and which had asymmetrical pieces.
We cheated a little, and went from oldest to youngest, to make it easier for the youngest two, who in this instance, did pretty well.

It's great to be a homeschooler.
