You need to plan a school sports day. Decompose this problem into smaller sub-problems.

Solution

    Step 1: Identify the major areas: events/activities, equipment, scheduling, participants, venue.
  2. 2
    Step 2: Break each area down further — e.g., Events: choose sports, set rules, assign referees. Scheduling: set times, allocate fields, plan breaks.
  3. 3
    Step 3: Each sub-problem is now small enough to tackle individually.

Answer

Sub-problems: choose events, organise equipment, create schedule, register participants, prepare venue, plan prizes.
Decomposition breaks a complex problem into smaller, manageable parts. Each part can be solved independently, making the overall problem less overwhelming.
