> Communication exercises for students that fit the start of a lesson: a one-module bomb warm-up, a seat swap and a four-week schedule to track progress.
Short communication exercises for students work well as lesson starters: ten minutes, once a week, the same format each time. A one-module bomb round fits that slot. One student describes a panel of wires, a partner reads the rule, they swap seats for a second round, and the teacher records strikes and repeat-backs to see progress.

## Why communication exercises for students work best short and repeated

A short communication exercise fits at the start of a lesson without stealing it, and a weekly repeat lets students apply last week's lesson before they forget it. A long one-off session teaches a lot once and then fades. A ten-minute exercise with a fixed format becomes a habit that students recognise and settle into quickly.

The fixed format matters more than the length. When students know the routine, the first minute goes on the task, not on instructions. That leaves room for the part that actually builds skill: trying, getting it wrong and trying again with a better sentence.

Repetition also gives the teacher something to compare. One session shows how a class talks on a single day. Four sessions in the same format show whether anything changed. Classroom communication activities that change every week make that comparison impossible, because each new format brings its own learning curve.

### Why a bomb works as the routine

Bomb Appétit has short missions that reset in seconds, which suits a repeated starter. The setup is identical every week: one screen for the bomb, the manual on paper or other devices, and students in pairs or small groups. First Bite always deals the same case, but a freeplay bomb, which the teacher builds with one chosen module, deals a fresh one at every start. The routine stays fixed while the content changes.

## The one-module communication exercise: First Bite in five minutes

The smallest useful round is First Bite, the first mission in the game. It puts one Wires module on the case with five minutes on the clock and three strikes allowed. One student describes the wires; another finds the rule in the manual and gives one instruction. Most of the ten minutes goes on talk, not on setup.

The Wires page in the manual tells the Expert to find the list for the number of wires, read it from the top and stop at the first line that is true. That gives the Expert a clear task with a clear end. The Defuser's job is equally clear: count the wires, name their colours from the top, and read out any edgework the rule asks for, such as the serial number.

### What a single round practises

One module is enough to practise the core loop: describe, ask, instruct, repeat back, act. The Defuser practises giving complete information without being asked twice. The Expert practises asking for only what the rule needs and turning a written rule into a spoken instruction. Both practise the repeat-back, where the Defuser says the instruction aloud before acting.

### Setting up in under two minutes

Keep the bomb device at the front with [Play](/play) already open; nobody needs to sign in. Hand out a printed Wires page for rule seed 1 to each Expert. Students can be in pairs, one Defuser and one Expert, or in groups of up to five, one Defuser and up to four Experts.

## Swapping seats mid-exercise: the Defuser becomes the Expert

Swapping seats inside one exercise means playing two short rounds back to back with the roles reversed. The first Defuser becomes the Expert for round two. This shows each student what their own words sounded like from the other side, which a single round cannot do. With First Bite, two rounds fit comfortably in ten minutes.

A student who has just been the Defuser knows how it felt to hear a vague instruction. When they take the manual, they have a reason to phrase their own instructions more carefully, because they remember what was missing. The same works in reverse: a former Expert who had to beg for the wire colours describes the bomb fully when they get the seat.

### How to run the swap

Play round one. When it ends, defused or not, the pair stands up and changes chairs. Because First Bite deals the same case every time, round two uses a freeplay bomb built with one Wires module, so the new Defuser faces a case nobody has described yet. The new Expert takes the Wires page. Then round two begins. Do not discuss the first round before starting the second; let the swap do the teaching.

### When the swap is not possible

In an online room the roles lock while the bomb is armed, so the swap happens between rounds, not during one. That is exactly how this exercise uses it, so a class playing in online rooms can run the same routine.

## How do you tell whether communication exercises are working?

Track three numbers each week on paper: strikes per round, how often the Defuser repeated an instruction back before acting, and how many times an Expert had to ask the same question twice. Falling strikes and repeated questions, with more repeat-backs, show the talk getting clearer. The game keeps no scores across rounds, so the teacher's sheet is the record.

Each number points at a different skill. Strikes measure the overall result. Repeat-backs measure listening and checking. Repeated questions measure how complete the Defuser's description was the first time. A class whose strikes stay flat but whose repeated questions fall is still improving, just not yet in a way the bomb rewards.

### The four-week warm-up schedule

The schedule below is an example. It uses the first missions in order and gives each week one focus phrase for the board and one thing to record. Every week runs ten minutes: two minutes of setup and two short rounds with a seat swap.

| Week (example) | Mission                                 | Focus phrase on the board           | What the teacher records                                                      |
| -------------- | --------------------------------------- | ----------------------------------- | ----------------------------------------------------------------------------- |
| 1              | First Bite (1 module, 5 min)            | "Describe before anyone asks."      | Strikes per pair, and whether the Defuser named every wire colour unprompted. |
| 2              | Freeplay, 1 Wires module                | "Say it back, then do it."          | Repeat-backs per round, counted on a tally.                                   |
| 3              | Button Up (2 modules, 5 min)            | "Ask only for what the rule needs." | Questions the Expert had to repeat, per round.                                |
| 4              | Freeplay, 1 Wires module, new rule seed | "New rules: check, do not assume."  | Strikes per pair, compared with week 1.                                       |

Missions always use their own fixed manual, so week four sets a new rule seed on a freeplay bomb and prints the manual for that same seed. A new seed rewrites every rule, so students cannot rely on memory, and the week-four strikes show whether the habits from weeks one to three hold up on unfamiliar rules.

## Which communication exercises need only one screen?

Any of these exercises can run with one screen if the manual is printed. The bomb stays on the single device at the front, and every Expert works from paper. A class with few devices can still run a full weekly routine, with pairs taking turns at the screen while others prepare.

The printed manual is laid out to print cleanly in black and white from the browser. For a one-screen class, print the Wires page in quantity and keep a class set. For Button Up, add the Big Button page. Check that the seed printed on the pages matches the bomb before each session.

### Taking turns at one screen

With one screen, run one pair at a time on a freeplay bomb with one Wires module, so each pair gets a case of its own, while the rest of the class watches from behind the Experts' side, where they cannot see the bomb. The watchers each hold a printed Wires page and silently work out the answer too. When their turn comes, they have already read the page once. Groups with several Experts can share a printed manual by [dividing the printed pages between Experts](/blog/print-and-play-games-one-screen-stack-of-pages#dividing-the-printed-pages-between-experts), so each owns a module.

### When a single screen is too slow

If turn-taking means most students only play once a month, the warm-up loses its weekly rhythm. In that case, keep the one-screen bomb for a demonstration pair and run the describe-and-draw part of the routine in pairs at desks. The [listening games for students that are heard only once](/blog/listening-games-for-students-hear-it-once) offer other short formats that need no screen at all.

## The exercise mistake: explaining the lesson before students struggle

The mistake is telling students the lesson before the first round, for example "remember to describe clearly and repeat instructions back". Students nod, then forget it the moment the clock starts. Let the first round go wrong. A strike from a vague instruction teaches the point faster than any explanation, and the explanation lands afterwards.

Struggle gives the lesson something to attach to. After a strike, a student knows exactly which sentence caused it. When the teacher then says "say it back before you cut", the advice answers a question the student already has.

### How much to say before the first round

Say only the rules of the game: who sees the bomb, who holds the manual, what a strike does. Do not give tips. The focus phrase goes on the board after week one's first round, not before it.

### Where to go from here

When a class is ready for a full lesson rather than a starter, [the full lesson plan](/blog/communication-skills-games-for-students-bomb-lesson#a-communication-skills-lesson-plan-around-one-bomb) builds a whole period around the bomb, and the [communication skills games for students](/blog/communication-skills-games-for-students-bomb-lesson) guide explains why vague words need a cost.
