Positive/Negative cutouts

This is a super lesson to do around the holidays. Students will first learn the terms ''related shapes '' and ''radial shapes''. On a 9'' black paper square, class will draw their design with pencil. Place design on a newspaper and cut using exacto knives. (...threaten first, and remove knife if anyone ''plays'' with it ).When design is cut out, use scissors to cut pieces of tissue to glue on the back...remind them that each shape has a different color. They may also use the knives to do the smaller pieces of tissue to fit. Display in any window using small pieces of masking tape.
