I had each of the kids gather 7 assorted items, and I did the same. Then they worked on figuring out how best to categorize the items. It got a little heated, as things tend to when both my oldest kids are involved.
As categories were suggested or tried I wrote them on the white board. After unsuccessful attempts to come to consensus, we decided to let each person have their own attempt to categorize. Here are the results:
After we finished, Zion wanted to try sorting them by color.
The sock and the cast iron bird statue seemed to be the most challenging items to find a good grouping for, according to the kids.
We then walked around the house and pointed out how things are organized and grouped together.
This part of the lesson took a lot longer than I anticipated, but the kids were enjoying it and pretty engaged, so I think it was time worth spending. We will hopefully wrap up when we have our next science class.
