This is a cute lesson perfect for younger elementary grades- I think I did this with my Grade 2's a couple of years ago. I found the lesson
HERE on the website "Raising Little Superheroes".
It's a great end of the year lesson as you can use up some of the scrap paper you have lying around.
Start off by having the kids colour in coffee filters using washable markers.
Then they sprayed them with water- we tried making monoprints by putting the wet coffee filter between two sheets of paper - it worked out fairly well. But we didn't end up using them for anything so I tossed them in my scrap paper bin, haha. The coffee filters need to dry overnight.
The next class, I had them sketch out a practice sketch to envision what
their creature might look like.
Then they used scrap paper from my big scrap paper box and cut out and
glued on the face and any accessories.
