How to play

  1. Read a true-or-false statement aloud to the class.
  2. Students tap the green TRUE or red FALSE paddle; the tally updates live as votes come in.
  3. Set which answer is correct using the TRUE/FALSE toggle, then press Reveal (or the space bar).
  4. Press Next Question to clear the tally and unlock voting for a new statement.

Checking whether a whole class understands a statement usually means picking a few hands and hoping they represent the room. This tool turns that guess into real data: read a statement aloud, students tap the green TRUE or red FALSE side of the screen, and the live tally shows exactly how the room split before you reveal the right answer. Mark which side is correct, press Reveal or hit the space bar, and both paddles highlight the answer with a calm confirming tone — no buzzers, no fanfare, just a clear formative signal. Press Next Question to reset the tally and run it again with your next statement.

Frequently asked questions

Can students change their vote before the reveal?
Every tap counts, so a student can tap the other paddle to add a vote there too — the tally reflects total taps, not one vote per person, which works well for quick gut-check reads of the room.
Does this tool use an air horn or loud sound on reveal?
No — this classroom version uses a single calm confirming tone on reveal, unlike the louder party edition, so it fits quiet formative-assessment moments.
Can I use the keyboard instead of clicking Reveal?
Yes, pressing the space bar triggers the same reveal as clicking the button, which is handy if you're standing away from the screen or trackpad.
