Although my sophisticated gentleman had already covered such topics in ps kindergarten, he was still very excited to get going. I let him sort them however he wanted so he chose colors.
Then we went with size (the ones on the right look smaller due to the camera angle but they are actually bigger than the ones on the left). We also had a weird shaped one which he is holding.
Then we sorted the lacing beads by color and discussed other ways we could sort them. We went on to talk about all the different things in life that are sorted into categories. We just went with the flow and it was a very natural discussion. Quite refreshing from the rather stale curriculum we have been doing up until now. I have certainly learned a lot about my son and the way he learns best. If only I had more money to get all new curriculum :) Oh well, we will have to make do for now.
