We've done several paper clip color match activities, and this is the most recent one. The idea for this activity came from another blog, and as usual I can't find it on my starred items on google reader (that is what happens when you have over 800 starred items!). To make the color match activity, I cut strips of craft foam and hooked them together using a brad. I showed O how to match the paper clips to the craft foam by sliding them onto the foam strips.
This activity was very difficult for O because the craft foam is very bendy. I will probably remake this activity for her using cardstock.
