I did a lesson on adjectives with the grade five class. We talked about what an adjective is, brainstormed positive adjectives, then they had to think of a positive adjective for each classroom.
I later used the adjectives for each student to create individual word clouds, printed them on fancy paper, and gave them to the students as gifts. They loved having a piece of art that told them all the nice things their classmates thought about them.
(You should have heard how excited one boy became when he discovered someone had described him as cute!)
