This lesson has digital and hands on assignments. It gives options to be modified due to materials available to the students. It includes art history, images, examples & art vocabulary. It gives the option of organic abstract paper/cardboard stacking sculptures or mobiles. It has a self evaluation sheet attached and links if you want to extend the length of the assignment. I have done the cardbaord lesson with middle school students and they really enjoyed it and were engaged. This is easy to implement and students can be self directed and given choice. This could last 45 min up to 3 hours.
