My plan was to hot glue some buttons on cardboard that they could wrap yarn and string around....but as we all know plans change all of the time! Instead, this child decided to start placing the buttons on the cardboard and took over. She worked with these buttons for 30 minutes; placing them, looking for ones that looked alike; thinking about putting them into a pattern...lots of great work and learning!!
Eventually, she was willing to share :)...The kids jumped in and had fun exploring the buttons in these trays as well.
