One Frog

Name and Purpose

• One Frog is a rhythm and memory game that builds listening, counting, and group coordination.
• Players practise keeping a beat, tracking a growing sequence, and staying focused while others try to throw them off.

a.k.a.

• Rhythm Frog, Frog Count, Kerplunk Circle

Age / Group / Time / Space

• Ages 8-16 | 5-20 players | 10-20 minutes | Indoor circle, seated on floor or chairs, low-noise environment preferred

Materials

• No materials required
• Optional: a hand drum or lap drum for keeping the beat
• A flat, hard floor surface makes the lap-pat beat easier to hear

Quick-Run Card

1. Sit in a circle. One person starts a steady lap-pat beat. Everyone joins.
2. Learn the chant: ONE FROG / IN THE WATER / KERPLUNK. Three players say one part each on the beat.
3. Round two: TWO FROGS / TWO FROGS / IN THE WATER / IN THE WATER / KERPLUNK / KERPLUNK.
4. Each round adds one more frog and one more repetition of each chant segment.
5. Players who lose the beat move to the centre to (gently) distract the group.

Setup and Boundaries

• Sit close enough in the circle that everyone can hear the lap-pat beat clearly
• Signal: leader raises both hands = everyone stops and resets the beat
• Agree on a “distraction style” before play: silly faces and sounds only, no touching

How to Play

1. Sit in a tight circle, cross-legged or in chairs.
2. One person begins a steady, moderate beat by patting their hands on their laps. Everyone joins in.
3. Learn the chant together before starting:
   • Round 1: ONE FROG (person 1) / IN THE WATER (person 2) / KERPLUNK (person 3)
   • Each segment is said once, on the beat, by a different person going around the circle.
4. Once the chant is understood, start Round 1. The first person says “ONE FROG,” the next says “IN THE WATER,” the next says “KERPLUNK.”
5. Without pausing, continue with Round 2: now everything is said twice. TWO FROGS / TWO FROGS / IN THE WATER / IN THE WATER / KERPLUNK / KERPLUNK. Each part still passes to a different person, one segment per beat.
6. Each round adds one more frog and one more repetition of every segment.
7. When a player says the wrong segment or breaks the beat, they move to the centre of the circle. Their role is now to distract the group with silly sounds and faces. They stay in for a set time (one full round), then rejoin the circle.
8. Keep the beat going. The game ends when the group reaches a satisfying number of frogs or time runs out.

I-OPt Options

• Start:
  • A (Active): Set the opening beat for the whole group
  • S (Support): Help teach the chant to newer players before the first round starts
  • Q (Quiet): Focus on learning the pattern by listening before adding your voice
  • O (Observer): Watch the first round before joining; slip in when there is a natural break
• Mid:
  • A (Active): Push to higher frog counts and encourage the group to keep going
  • S (Support): Quietly cue the next person if they look uncertain about their part
  • Q (Quiet): Keep your part of the chant understated but steady
  • O (Observer): Count the frogs and announce the round number to help the group track progress
• Centre (distraction role):
  • A (Active): Go all-in on silly distraction
  • S (Support): Keep distractions gentle so others can still focus
  • Q (Quiet): Use only a small smile or gentle movement as your distraction
  • O (Observer): Watch who breaks next and enjoy the moment without adding pressure
• End:
  • A (Active): Lead one final push for the highest frog count the group can achieve
  • S (Support): Celebrate the group’s highest count together
  • Q (Quiet): Smile and enjoy the finish
  • O (Observer): Share one moment that made you laugh or impressed you

Inclusion Adaptations

• Players who cannot pat their laps can tap a finger on a flat surface or nod their head to keep the beat
• Players with speech or rhythm challenges can hold a card that says their chant segment and point to it on their turn instead of speaking

Stewardship Moment

• No materials. Zero footprint.
• Reflection: “This game runs entirely on rhythm and listening. What else in your day works better when everyone is in sync?”

Consent

• Pre-brief: “When you lose the beat, you move to the centre for one round. Your job there is to make people laugh with silly faces and sounds. For those not comfortable with that spotlight, you can simply return to the circle quietly and keep patting the beat. Both are completely fine.”
• Mid-game check: After the first few rounds, pause. “How is the pace? Thumbs up, sideways, or down.”
• Opt-out/re-entry: Any player can rejoin the circle from the centre at any time. No penalty for stepping back in early.

Risks and Mitigation

• The beat collapsing when too many players move to the centre: cap the number in the centre at 2-3; others rejoin automatically when the cap is reached
• Players feeling embarrassed in the centre role: frame the centre as a fun performance spot, not a penalty; model the distraction yourself in the first round
• The chant becoming too complex for the group to track: reset to a lower frog number and rebuild from there

Warm-Up Suggestions

• “Clap Echo”: leader claps a rhythm; group claps it back exactly; increase complexity over 5-6 rounds
• “Body Beat”: go around the circle, each person adds one percussive body sound (clap, snap, stomp, tap) to a shared groove

Debrief Questions

• What? “What happened to the group’s focus as the frog count got higher?”
• So What? “What made it easier to stay on the beat? What made it harder?”
• Now What? “When do you need to stay focused in real life while things around you are getting louder or more distracting?”

Cleanup and Reset

• No materials to collect
• Return any borrowed percussion instruments
• Reposition chairs if moved
