Mix-Freeze-Group

Students mix; on freeze, they form groups of the number the teacher calls. Mathematical chaos that produces fresh groupings in seconds, with a question prompt each round.

Procedure

1. Students stand and mingle. Mix! Music plays; students walk around greeting others briefly.
2. Freeze! — everyone stops.
3. Teacher calls a number: Groups of three! / Groups of five!
4. Students scramble into the called group size. Anyone not in a group sits out the round.
5. Groups get a quick prompt (30–60 sec): Name three things you all have in common / Decide which of you has travelled furthest / Share one word to describe the week.
6. Mix! again. Repeat 4–6 times with different numbers.

Why It Works

• Group size becomes variable: students experience pairs, trios, fours in one session.
• Failure is low-cost: students who don't make the group sit out one round; that's all.
• Music + count signals rhythm: natural transitions no yelling required.

Prompt Ideas

Group size	Prompt
2	Share one weekend plan.
3	Find one thing all three of you have never done.
4	Agree on the best restaurant in town.
5	Build a sentence using all five of your favourite words from this week.

Variations

• Maths challenge: teacher calls "Groups of half the class's age average!" Students work out the number. Numeracy + English.
• Attribute version: Group by shoe colour / birthday month. Students self-sort silently.
• Frozen pose: on freeze, students must hold a pose until group forms — pure fun energy booster.

Tips

• Fast reset — 45 seconds of music, 2 minutes of group talk, 45 seconds of music. Don't let any phase drag.
• Use as transition between lesson segments or as an emergency re-energiser when attention is fading.
• Sitters-out have an important role: observer. Ask them who formed groups fastest.
