Here is the final product:
Start with pans of red and pink (red mixed with white since I didn't have pink) paint. I use washable so easy to clean off the kids. I threw a heart shaped sponge in each pan.
Then I cut out a heart shape on construction paper and used that to trace all the hearts on white poster board.
Let the kids sponge paint the white heart as much as they want to with whatever color they choose. Then add two googly eyes to the top.
Once the hearts are dry, I sat the kids down and gave them strips of red paper. They folded them back and forth accordion style and glued a precut red heart on the end of each so it looked like they were arms with a heart hand. Then we used glue sticks to glue the "arms" on to the big heart they had made. They used my purple sharpie to draw a mouth. I wish I had pictures of them folding the paper strips but I forgot to take them. So hopefully you can see the arms well enough in the finished product picture here:
HAVE FUN!!!
