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.
Sleepyhead Designs Studio: Snowman Lesson-Shaving Cream and Glue- messy but cool results.equal parts of shaving cream and elmers glue to make puffy paint (she added more glue to make it more tacky/sticky)
Art Projects for Kids: Snowflake Art Trading Cards. Punched snowflakes glued to painted watercolor paper. Love these - even little kids could do a series of these in diff winter/Christmas themes, and could gift them to mum and dad as gift tags:)
