I teach this sculptural Monet project to 2nd grade each year. I usually wait until the very end of the semester to do this project and I think I may squeeze it in a little earlier next year.
We start with building 3-D waves...I used an 8"x8" square of blue paper this year for the base. Cut the paper strips from a 9x12 paper so you have the ability to create the waves...
This could be a one day project...but I usually chunk it into two class periods...Day One Waves and Lily Pads...Day Two: Water Lilies and Frogs
A first grade teacher at my school who integrates art a lot into her classroom told me about making coffee filter flowers and they turned out beautifully!
