You have four jobs before Sports Day: food, seating, music, prizes. Looking at the list does not help.

Split the work into small jobs. Then each job becomes easy.

This track's six ideas, in order.

What this track covers

  • Split a big job into smaller, named parts.
  • Spot the repeat — a long pattern becomes short.
  • What is an algorithm? — exact steps, in order.
  • Follow steps exactly — see where they work or break.
  • Test the tricky case — one that may break your rule.
  • Sorting — putting things in order, one small rule at a time.

None of this needs a computer. A pencil is enough. Each idea has a small lab. Open it and try.
