We've been working on the concepts of open and closed lately, so this activity from Montessori Mama fit in perfectly with that. I found the bag clips from Family Dollar, but I was disappointed that they only had red and blue. O was excited when I showed them to her, and she immediately grabbed a blue one and said "boo." She open and closed them for a bit, but she had the most fun putting them in and out of a tall white container (I'm not sure where this container came from. It just appeared on the shelf. Grandmas- did one of you bring it over?). O was holding the container somewhat upside down while she was putting the clips in it, so they kept falling out. She was a little perplexed as you can see by the picture.
