First she sorted the cereal by color in this divided dish. I think I got this at Dollar General-it's meant to be a dip serving tray, but works great for sorting and for holding various materials for collages and what-not. Then she laced them onto a string of yarn that had masking tape around the end. I think she choose not to do ROYGBIV order, but if we revisit this this year I'll make her since I know she's ready for that.
She proudly wore the necklace for a short while before gobbling it up!
We also attempted rainbow cookies. They were cute, but the dough was really crumbly. After making a couple we decided to mix all the colored sprinkles together and top off circle cookies with the mixture.
We did some other activities that I failed to photograph. B used dot markers on a rainbow sheet; we made a wind catcher out of a paper plate and crepe paper streamers of all the colors of the rainbow; and I'm sure some other things that have slipped my mind. It was a fun "theme". That we may look into again.
