Case practice at the dinner table: a family guide for competition training.
Case competition skills grow with practice, and families can provide some of it. A short case conversation at home builds structure, numbers sense and calm under questions.
Why practice at home helps
Students preparing for a case competition usually train with their team and a coach. That practice is essential, but it is limited by schedules. Short, regular practice at home can fill the gaps: explaining a structure out loud, doing quick estimates and answering follow-up questions under mild pressure. These skills improve with repetition more than with long sessions.
Families do not need business training to help. The role at home is not to be a judge or a consultant, but to be a curious listener who asks the student to explain clearly. That alone recreates much of what happens when a judging panel asks questions after a presentation.
A fifteen-minute format
Keep each session short and predictable. Spend two minutes on a prompt, five minutes for the student to structure an answer out loud, five minutes of questions and three minutes on what to improve. Fifteen minutes fits after dinner and is short enough to repeat a few times a week.
Use a timer. Time pressure is part of case competitions, and practising with a visible clock helps students learn to prioritise. But keep the tone relaxed. The aim is steady improvement, not to recreate the stress of the final round.
Finding everyday case prompts
Good prompts come from everyday life. A local café is getting fewer customers; how would you find out why? A school club wants more members; what should it try first? A family is choosing between two holiday options; how should it decide? These questions use the same thinking as business cases without needing industry knowledge.
Students can also bring practice prompts from their coach or past competitions, if the program allows it. Avoid using real, confidential information from a parent's workplace; it raises fairness and privacy problems and is not needed for good practice.
Listening for structure
As the student answers, listen for structure rather than the right answer. Did they state the question clearly? Did they break the problem into a few distinct parts? Did they say which part they would look at first and why? Families can note these points without judging the content.
A helpful prompt afterwards is: can you summarise your approach in three sentences? If the student struggles, the structure was probably unclear. Practising a short summary helps with the opening of a presentation and with answering judges concisely.
Asking follow-up questions
Follow-up questions are where the learning happens. Ask why that part first, what would change your mind, and what is the biggest risk in your recommendation. These are questions judges often ask, and they push the student to defend reasoning rather than repeat a framework.
Ask one question at a time and let the student think. If the answer is weak, do not correct it; ask another question that helps the student see the gap. The goal is to strengthen the student's thinking, not to show your own.
Practising quick estimates
Many cases involve simple estimation. Families can practise this casually: how many cups of coffee might a café sell on a weekday, how many students might join a club. Ask the student to explain each assumption and round sensibly. The answer matters less than a clear, checkable chain of reasoning.
Encourage the student to state assumptions as assumptions, not facts. In competitions, teams that label their estimates honestly are easier to follow and easier to trust.
Supporting the team, not replacing it
During a competition, the work must be the team's own. Families should not draft slides, write recommendations or research a live case for the team. Follow the competition's rules on outside help, which often restrict it during the case window.
Families can support in other ways: quiet space, meals, transport and encouragement. Before a competition, practice at home is helpful; during the case window, the best support is usually practical and invisible.
A sample session
Take the prompt: a neighbourhood bakery's weekday sales have fallen while weekend sales are steady. The student restates the question, then proposes a structure: changes in customers, changes in the bakery's offer and changes in local competition. They choose to start with customers, because the weekday pattern suggests something about who visits on workdays.
The family listener asks why customers first, what one piece of information would test that idea and what the bakery could do this month if the idea is right. The student answers, stumbles once and recovers. In the last three minutes they name one improvement: state the starting hypothesis earlier. That is a complete, useful session.
Including the whole household
Siblings and grandparents can make good practice audiences, because they ask questions a coach might not. A younger sibling may ask why a business cannot just lower its prices, which is a fair question the student should answer simply. A grandparent may ask about customers a teenager overlooked.
Rotate who asks the questions so the practice does not depend on one person's style. The more varied the listeners, the better the student becomes at explaining the same reasoning to different audiences, which is what a final round with mixed judges requires.
After a competition
Whatever the result, ask the student to talk through what went well, what the judges asked and what they would change. Help them note specific lessons, such as starting with a clearer question or checking numbers earlier, rather than general feelings about the outcome.
Keep those notes for the next round of practice. Over a season, families who listen regularly will notice real progress in how clearly the student structures and defends ideas. That progress is the honest measure of training, independent of any single result.
