I bought the smaller sized poster board for the arms, legs, and white eyeball. I used normal black construction paper for the mouth and pupil.
I re-used a large piece of pink poster board that I made a Valentines Day countdown on.
I flipped the poster board over and cut out the monster on the unused side. I free handed everything, so it isn't perfect, but what monster is?! To do the 100 dots, I bought a set of plain circle dot stickers.
Kit was nice enough to let Kat help add sticker, it took them about 5 minutes to get them all exactly where they wanted them. I only took me about 10 minutes to get everything drawn and cut out. The whole 100th day of school project will only cost you about $4.
This was a fun one to do. A big plus, it was completely different from the rest of the class! All the kids loved it!
