Answer Key
Years 5–6 Creating Digital Solutions · Modules 1–10 · Student wording will vary for definitions
1problem — Something difficult or annoying for someone. Some problems can be solved or made easier by a digital system, like an app, but others need something non-digital, like a tool.
2user need — Something a user must be able to do or have to finish a task or fix their problem. A need is not just a want. We write it as: The user needs to...
3[User] needs a way to [do something] because [reason] — A problem statement is one sentence that names the user, says the task they need to do, and gives the reason why it matters. It turns a vague idea into a clear problem.
4The solution must — Starts a functional requirement: one thing a digital solution must do. It says what the solution does, not how, and covers one action. Example: The solution must show the score.
5co-develop requirements — Work with your teacher, the user and classmates to ask questions, list what the solution must do, and agree on a final list of requirements.
6success criterion — A checkable statement about what a solution must do for the user, like 'The user can log in.' You check it with yes or no to see if the solution works.
7decomposition — Breaking a big problem into smaller parts, so each part is simple enough to solve in a few steps. You can then choose one part to solve first.
8algorithm — A set of clear steps, in order, that solves a problem or completes a task, like a recipe or morning routine. Each step must be precise so a person or computer can follow it.
9sequence — Steps that run one after another in a set order. Changing the order, leaving a step out or adding an extra step can change the result.
101. Get a bowl — A written algorithm step. Each line has one number and one action, and starts with a command word like Get, Add or Show. Steps go 1, 2, 3 in order.
