I mentioned this logical puzzle in my previous posts. Eaton at that time wasn't ready for it yet. We tried that puzzle few times but I saw he couldn't grasps that idea so I put it away for a while. Few days ago I took it out from my storage and shown Eaton again. I was pleased that he was ready to do that type of puzzle by himself. This video shows the first time we worked together, but after that he didn't need my help anymore. Now he is doing it on his own. Maybe next week I will show him another set of logical puzzle where there are 2 shapes in one puzzle square.
I like this puzzle a lot. It reminds me my childhood when I did enjoy doing them.
