Stickers 

By far, the favorite project I've had the kids do is DIY sticker making. This is one of the few art projects I've seen 1st and 5th graders alike excited to do. 

Start with parchment paper, layer packing tape over the top, place the cut-out design on top, and cover with a second layer of tape. Cut the sticker, leaving some overlap of the tapes, so it doesn't fall apart. For older students, they were allowed to use Chromebooks as a light table to trace their favorite sports teams and characters, or to find ideas.
