Letter Number Name
Letter Number Name is a cognitive multi-tracking warm-up exercise in which participants move through a sequence cycling between three categories -- a letter of the alphabet, a number, and a proper name -- simultaneously advancing each sequence independently. The exercise disrupts automatic cognitive patterning, trains the ability to hold and advance multiple concurrent sequences, and activates the focused concentration required at the start of a rehearsal or workshop.
Structure
Setup
Participants stand in a circle or work individually. The facilitator explains the three simultaneous sequences that each participant must maintain: the alphabetical sequence (A, B, C...), a numerical sequence (1, 2, 3...), and a sequence of proper names (one per turn, any name, continuing alphabetically or freely).
Progression
Starting with the first participant, each person calls out one element from each sequence in order: "A, 1, Alice." The next participant advances all three: "B, 2, Ben." Each participant must track where the previous person left off in all three sequences simultaneously.
Variations may introduce random assignment of which sequence each participant must advance, or require the three elements to be delivered in a different order each round.
Conclusion
The exercise concludes after the group has successfully completed multiple rotations through all three sequences, or when the facilitator determines that the desired level of cognitive activation has been achieved.
How to Teach It
Objectives
Letter Number Name targets cognitive flexibility, divided attention, and the ability to hold multiple concurrent tracks in working memory. As a warm-up, it shifts participants from a distracted or passive mental state into the focused, multi-track attention that ensemble scene work requires.
How to Explain It
"Three things at once. You know where the letters are, you know where the numbers are, and you need to know what name just got used. Keep all three tracks running in your head and advance all three when it's your turn."
Scaffolding
Begin with just two sequences (letter and number) before adding the third. For groups very new to this kind of exercise, allow a brief pause between elements in the first round before increasing pace.
Common Pitfalls
Participants frequently lose one sequence while tracking the other two, or advance only one sequence and treat the others as static. The exercise is most diagnostic in these moments: which sequence drops reveals something about each participant's cognitive prioritization under mild pressure.

Name Volley
Name Volley is a name-learning exercise in which two or more participants pass each other's names back and forth in rapid succession, maintaining a rhythm similar to a volleyball rally. The exercise develops quick name recall, sustained eye contact, and the physical and vocal commitment that comes from treating someone's name as an object in motion.
Ten Titles
Ten Titles is a warm-up exercise in which a player must rapidly generate ten show titles, song names, book titles, or scene suggestions on a given topic. The speed prevents self-censoring and builds the habit of generating material without judgment. The exercise is often used to loosen up performers before a brainstorming or scene-work session.
Digits
Digits is a quick-reflex number game in which players hold up a number of fingers and must instantly shout the total shown by all players. The exercise demands rapid mental arithmetic and group attention. It works as a fast warm-up that sharpens focus and peripheral awareness.
Mexican Name Wave
Mexican Name Wave is a group name-learning and energy exercise in which participants pass their own name around the circle in a wave pattern -- each person calling their name with a specific vocal and physical gesture, with the group mirroring it back, then passing to the next person. The exercise builds name retention through repetition and physical engagement while generating group energy and the shared experience of collective attention.
Time Bomb
Time Bomb is a fast-paced game in which players must complete a task, answer a question, or contribute to a scene before an imaginary or real timer expires. The countdown creates urgency that eliminates hesitation. The game rewards quick instincts and teaches performers to trust their first response.
Brain Drain
Brain Drain is a rapid-fire listing exercise in which a player must name as many items as possible in a category before time runs out. The speed prevents self-censorship and trains the associative thinking essential to improvisation. It can be played individually, in pairs, or as a group warm-up.
