Of course it was late at night when I put this together, and I realized after the fact that I put his tree together backwards and he was working on the "back" with the stray pen marks. Oh well, right?
I had hardly starting explaining symmetry when he set to work. We had discussed the term similar before, and I think he was basing this activity off of those discussions, because the words similar and symmetry sound alike.
This was his first attempt, and other than his arm knocking the ornaments around as he decided where to place the next ornament, I think he did good for the first try. I asked him if he wanted to glue them on so we could fold the tree in half and see how the pieces matched up, but he said no. I think he wanted the option to work it again later.
(I was inspired to make this symmetry tree after I made this Ornament Matching game for my 2 year old)
We will also be exploring symmetry with the classic coffee filter snowflakes soon! I know he will love that one!
