Alphabet Letters as Art: each letter is on an individual colorful canvas; each created in a class project and as unique as the individual that created it. This is really a great idea for learning and creative in a team effort.
Maybe a class project for Valentine's Day? Teacher could trace arm/hand for trunk and each child can find red/pink in magazine, trace a heart and cut out. Tree of Hearts collage made of old magazines. Trace hand and arm for the stem.
