cheap and simple, but very versatile

i was thinking about color lessons today.....and made this!
black foam core:$1.99
velcro:$1.49
construction paper and lamination: free from my wonderful host teacher.

very handy because the kids can pull off any colors and stick them back easily. can be used as a kind of formative assessment (ask them to pull off primary colors, complements, etc.), plus it looks cool on the wall!
