A single bomb round can anchor three speaking and listening activities: a describe-it warm-up before the clock starts, a swap rule that changes who speaks at every strike, and a retelling task once the round ends. Together with the round itself and a short class share, five activities fill a fifty-minute lesson without crowding it.
Speaking and listening activities before the round: the describe-it warm-up
The describe-it warm-up is a speaking and listening activity in pairs, sitting back to back. One student holds a card with a simple shape or symbol and describes it; the other draws it from the words alone. After two minutes they compare drawings and swap. It rehearses exactly the talk the bomb will demand.
The warm-up works because it isolates one skill. In the round, students juggle the timer, the manual and the bomb at once. In the warm-up, they only describe and listen. The comparison at the end gives instant feedback: a drawing that looks nothing like the card shows where the description failed.
Choose cards that are hard to name. A plain square is too easy. A shape with a bar across it, a ring with a dot inside or three uneven prongs makes students reach for position words: left, above, inside, touching. Those are the words they will need when the Defuser has to describe a symbol with no obvious name.
Phrases to put on the board
Give students three sentence starters before they begin: "It looks like...", "On the left side there is...", "Is it more like... or...?" The first two help the describer. The third gives the listener a way to ask for detail without saying "What?"
Why back to back
Sitting back to back removes pointing and gestures, which is the position the Experts are in at the bomb. A student who says "this bit here" during the warm-up learns at once that it means nothing to a partner who cannot see.
During the round: a speaking and listening swap at every strike
The swap rule says that every time the group takes a strike, the Expert who was giving instructions goes silent and the next Expert takes over, and the Defuser must describe the current module again from the start. One mistake changes both who speaks and what gets heard, so no student settles into only one skill.
Bomb Appétit splits a group into a Defuser, the one student who sees the bomb, and Experts, who hold the manual and cannot see it. Without a rule, one confident Expert can end up doing all the talking while the others search pages quietly. The swap spreads speaking across the Experts and forces the Defuser to repeat a description to a fresh listener.
Why tie the swap to strikes
A strike is a mistake: a wrong cut, a wrong press. Strikes also speed up the countdown, so the group feels each one. Tying the swap to a strike makes it a natural reset point. The group has just learned that something in the talk went wrong, and a new voice is a quick way to try again.
Keeping the swap fair
Line the Experts up in a fixed order before the round so nobody argues about who is next. If a group reaches its last Expert, the order wraps back to the first. In a group with only one Expert, the swap becomes a rule that the Defuser repeats the whole description before the next instruction.
After the round: retelling the defusal as a speaking and listening task
The retelling task asks each group to tell another group, in order, what happened in their round: what the Defuser saw, what the Experts asked, where it went wrong and how it ended. The listening group must ask two questions before the tellers sit down. It turns a noisy five minutes into a structured spoken account.
Retelling practises skills the round itself does not. During the round, talk is fast and broken into short exchanges. A retelling needs sequence, connecting words and a clear ending. Students have to agree on what happened, which can surface disagreements they did not notice in the moment.
A simple frame for the retelling
Give groups a frame with four lines: "First we...", "Then the Defuser said...", "The hardest moment was...", "In the end...". Each member speaks at least one line. The listeners' two questions must start with "Why" or "How", which pushes them past simple facts.
Pairing groups for the retelling
Pair groups that played different missions, if you ran more than one. A group that played Button Up has something new to tell a group that only played First Bite, and the listeners have a real reason to pay attention.
Which speaking and listening activities suit the youngest classes?
For the youngest classes, below grade 3, the describe-it warm-up and the Defuser's seat suit students best, because both ask for describing and counting rather than reading. The manual is written text, so put an adult or a confident reader in the Expert seat and give young students the job of describing what they see.
Young students can describe colours, count wires and say which one is at the top. Those are exactly the details a Wires module needs. The adult reads the manual line aloud, then turns it into an instruction for the child: "Cut the second wire from the top." The child repeats it, then cuts.
Adapting the warm-up
Use picture cards with familiar objects arranged in a simple scene: a cat beside a red box, a ball under a chair. Young describers practise position words with things they already know names for. Keep each turn short, a minute or less, and swap often.
Skipping the retelling
The full retelling is a lot for a young class after an exciting round. Replace it with one sentence each: "My favourite part was..." Students still practise speaking to the group and listening to their classmates, without the weight of a structured account.
How many speaking and listening activities fit in one lesson?
Five activities fit in a fifty-minute lesson if one of them is the bomb round itself: a warm-up, a short drill, the round, the retelling and a class share. More than five leaves too little time to finish any of them properly. Fewer than three wastes the round, because students need time both before and after it.
The step list below is an example plan with minutes, grouping and what students say. Change the minutes for your lesson length, but keep the order.
- Describe-it warm-up (8 minutes, pairs back to back). One student describes a symbol card; the partner draws it. Students say: "It has a ring with a dot in the middle, and a line underneath."
- Repeat-back drill (4 minutes, same pairs). One student gives a one-step instruction about the drawing; the partner repeats it before doing it. Students say: "Shade the left half." "Shade the left half. Done."
- The bomb round with the strike swap (15 minutes, groups of four). Set up, then play one round of First Bite or Button Up, each with five minutes on the clock. Students say: "Strike. Next Expert, your turn. Defuser, describe it again from the top."
- Retelling (13 minutes, two groups together). Each group retells its round using the four-line frame; listeners ask two Why or How questions. Students say: "First we read the serial number. The hardest moment was the button."
- Class share (10 minutes, whole class). Each group names one sentence that helped them and one that caused a strike. Students say: "The best thing anyone said was 'count from the top'."
Running more than one bomb
If the class has enough devices for several groups, each group runs its own bomb in step three. With only one device, run the bomb at the front and let groups take turns while the rest prepare their retelling frame. For the room layout and timing of a full period, the communication skills lesson plan around one bomb gives a complete version.
Checking what students learned
Assessment fits best during step three, when talk is fastest. The guide on assessing both skills during a bomb round sets out what to observe at each level.
The speaking and listening activities mistake: talking about the bomb instead of to each other
The mistake is letting the lesson drift into students talking about the bomb as a topic, its rules, its sounds, who was best, instead of talking to each other to solve it. Talk about the bomb is chat. Talk to a partner who needs your words to act is practice.
Keep every activity pointed at a listener who depends on the speaker.
The drift happens most after a round, when excitement is high. Students want to discuss the explosion or argue about whether a rule was fair. That conversation has energy, but it rarely practises listening, because everyone is speaking at once and nobody has to act on what they hear.
The retelling frame and the class share both guard against it. Each gives the speaker a specific listener and the listener a specific job: ask two questions, name one helpful sentence. When students know they will have to repeat or question what they heard, they listen.
A test for any activity
Ask one question of every activity in the lesson: does a student have to do something with what they just heard? If yes, it is a speaking and listening activity. If no, it is a discussion that may be pleasant but does not practise the skills.
Where to go next
A class that enjoys this plan can build a short weekly habit from it. The communication exercises for students in ten minutes shrink the round into a lesson starter.
