I set up this activity using the leaf rubbing plates I purchased last year from Let's Explore. I cut up some small pieces of natural recycled drawing paper from Discount School Supply and placed them in a basket. Then I chose 6 leaf rubbing plates and put those into another small basket. Finally, I added a little basket of crayon rocks (also from Let's Explore) and a pencil. The crayon rocks are perfect for this type of activity as they have a lot of surface area for rubbing. Additionally they help refine and strengthen a child's pincer grasp.
To do this work the child places the brown paper on top of a leaf plate and rubs the crayon rock over the top until the leaf image is revealed. I love how this looks on the brown paper.
Ideally it would be perfect to do this with real leaves. However, with 60 children (over the course of a week) handling the leaves I haven't yet figured out how to make the leaves hold up. If you have any great suggestions for how you've done this in a classroom setting, please let me know!
