Students who finish that next big test early can come to your desk, pick up a sheet or two of paper, and take a good long look at this paper snowflake dragon.
Back to their seats they go, with the instructions to create similar snowflakes. Use only pencils, erasers, paper, cutting utensils, and a whole bunch of brain cells. No electronic gadgets.
The reward? Your call, but I’d go find that roving school newspaper reporter.
