It was kind of fun. We cut out circles and folded them and folded them and folded them (to see how many lines of symmetry we could make - decided it could be an infinite number if we could fold closely enough together :) ) then we folded black paper and drew triangles. Luckily a few of them - totally by luck - turned out to be equilateral so we were able to discuss the fact that different shaped triangles had different numbers of lines of symmetry.
At this point a bright little spark shouted out that we were making witches :) so I was able to move on to the bodies quite easily.
The only rules were that every body part had to be cut on a fold so that it was symmetrical - it had to have at least one line of symmetry - and the kids had to fold every piece so that they could count the lines, before adding it to their picture.
I have to say they didn't manage all the directions perfectly but they didn't do a bad job. :)
|I liked this dress - with one line of|
symmetry neatly folded :)
|And look at the adorable stockings and shoes!|
When their pictures were finished we labelled them with lines of symmetry on one side and names of polygons on the other side - a combination math lesson!! If the shape wasn't a polygon they had to write "not a polygon" beside it. :)
It certainly showed me who still doesn't know the names of polygons (and who doesn't know what a polygon is at ALL) but in the end all the little witches turned out beautifully.

|Another cute little witch!|
|And a whole pile of symmetrical little witches!!|
My girls weren't too sure if they were doing Math or Art :) but isn't that the best type of lesson anyway? Hopefully they'll remember something about lines of symmetry!!
I think we'll do some more symmetrical Halloween stuff - bats and pumpkins would be fun. I'd quite like to have garlands of symmetrical bats flapping around the classroom.
Maybe tomorrow! :)
