I find that the following rules and organization support a game like this.
- Make mixed ability teams of four
- Make the spokesperson someone who doesn't speak up as much.
- Tell students that all team members have to agree on the answer before the spokesperson speaks.
- If one group doesn't get the answer right it goes to the next group for an additional point and continues to move forward with one point added each time until a group gets it right.
- If the students get antsy, call an all-play round and give every team who gets it right the point.
- Pass out white boards and pens that teams can use as they play.
- Keep the pace quick and use a microphone if one's available to give it that game show feel.
