Here is the most recent project that I made with my little pumpkins:
We ripped paper.
...and we had FUN!!! :)
*If you want to make this a mini lesson: begin by reading a seasonal book or two, sing some way cool pre-school Halloween songs, make funny faces at each other (to get them to understand expression) and most importantly, have fun!!! Big kids can follow up with a short story, poem, etc.
