Find every circle that is open at the top and tap or click it
This is a solo practice run: your results stay in this browser tab and are never sent anywhere. To contribute to a class result, join a live session with a code instead.
This task is new to Classperiment and has not yet been fully tested. Issues may occur in the procedure or scoring. The expected effect may also fail to appear reliably.
Task time: 2–4 min
Find all circles that are open at the top and tap or click them. Circles you have marked stay crossed out. Search as completely as you can. When you are done, choose “Done”. The field ends after one minute at the latest.
Every new tap or click marks one circle; tapping it again does not remove the mark. In the two search fields there is no feedback. In a classroom session, the explanation and results appear after the instructor releases them.
1 practice field (up to 30 s), then 2 search fields (up to 60 s each)
