The move
Give everyone think time, then pull a name stick at random so anyone could be asked.
See how it works
At a glance
- Time in class
- Ongoing; seconds per question
- Prep
- One-time: write each student’s name on a craft stick (10 minutes), or use a random name picker.
- Materials
- Craft sticks and a cup
- Grouping
- Whole class
- Use it when
- Any time you ask the class a question
Why it works
When only volunteers answer, the same few students do the thinking. If anyone might be called, everyone prepares an answer. In one study, regular cold-calling increased how often students volunteered and made them more comfortable speaking.
Step by step

Before class: Set the norm
- Set the normOnce“In here, everyone thinks. I’ll pull names at random, and you can always phone a friend.”
- Ask the question5 secondsNo hands.
- Think time5–10 seconds“Think. Everyone have an answer ready.”
- Pull a stick2 secondsRead the name.
- SupportAs neededIf they’re stuck: “Want to phone a friend, or hear it again?” Come back to them after.
- Return the stickPut it back so anyone can be called again.

“What sound does ‘ph’ make?”
“What’s one cause of the drought in this article?”
“Predict what happens to the price if supply drops.”
Watch out for
- “Gotcha” questions: use it to include, not to catch.
- No think time: always pause before pulling.
- Taking sticks out after they’re used: students stop listening once called.
Level up
- Pull two sticks, and the second student has to build on the first.
- Pair it with Boards Up! so everyone answers first, then you pull a name to explain.
Make it work for everyone
- Multilingual learners: let them rehearse with a partner before you pull.
- IEP and 504 supports: pre-warn a student privately before a question you’ll ask them.
Tech option
Any random name picker on the board works the same way.
