Take a piece of paper and draw 30 circles. Put your timer on for 2 minutes. Now transform all 30 circles into something else (e.g. a ball, donut, clock, ...). When the time is up, assess your creations. How many circles did you fill up? Are there any recognizable patterns or are any of the ideas related, fx. several planets or different sports balls. Was the task challenging? Did you or someone “break the rules” by combining circles or unexpectedly using them?
