The move

Everyone votes on a question, partners who chose differently try to convince each other, and then everyone votes again.

Time in class
5–8 minutes
Prep
2 minutes: write one multiple-choice question.
Materials
None. Students vote with fingers.
Grouping
Individual vote, then pairs.
Use it when
You’ve just taught a concept and want to know if it stuck before moving on.

Why it works

Explaining your answer to someone who disagrees forces you to check your own reasoning. In classes that use this routine (called peer instruction), the number of correct answers usually goes up after partners talk, even when only a few students were right at first.

Step by step

In class: about 4–6 min

  1. 2Ask30 seconds
  2. 3Vote 130 seconds
  3. 4Convince2 minutes
  4. 5Vote 230 seconds
  5. 6Reveal1–2 minutes

Before class: Write the question

  1. Write the question2 minutes, before classGive it 3–4 answer choices. Make the wrong choices tempting: use the mistakes students usually make.
  2. Ask30 seconds“Think on your own. No talking yet.”
  3. Vote 130 seconds“Hold up 1, 2, 3 or 4 fingers against your chest so only I can see.”Note the spread, but don’t reveal the answer.
  4. Convince2 minutes“Find someone who voted differently. You have two minutes to change their mind, or let them change yours.”
  5. Vote 230 secondsSame finger vote.
  6. Reveal1–2 minutesGive the answer and ask a student who switched: “What changed your mind?”

    Quick rule: if nearly everyone is right on vote 1, skip the discussion and move on. If nearly everyone is wrong, reteach before voting again.

Tech option

Any polling tool works for the two votes, such as Google Forms or a live poll. Finger votes are faster and need no devices.

Reflect

Which wrong answer was most popular on vote 1? That misconception is worth a few minutes tomorrow.
