The teachers at my school kid that I'm some sort of art expert, which is absolutely hilarious because I am not a skillful artist, whatsoever. I am just good at finding lesson plans on the internet! Here's one of the lessons on pointillism I taught a few weeks ago. I was pleasantly surprised with how it turned out, considering the kids are only 7 and 8 years old!
First I taught them how to draw a 3-D house. Next I showed them that instead of mixing two colours together, you can place them side by side to get the same effect. If you're far enough away, the two colours look like they are mixed.
It's neat when you walk down the hallway because the art just looks like paintings of houses until you get close up and see that it's made only from dots.
It's a good thing when art turns out better than I expected and I have something to decorate the bulletin boards with!
