Write the Algorithm

Preteen writes precise step-by-step instructions for a task and a parent follows them literally, exposing gaps in logic.

Your child writes exact step-by-step instructions for a simple task, then you follow them literally, doing only what is written. A funny, revealing game that shows where the logic has gaps.

How to do it

  1. Pick a simple physical task, such as making a sandwich, drawing a shape, or building a small tower.
  2. Have your child write the steps as precisely as they can, in order, assuming the follower knows nothing.
  3. Follow the steps out loud exactly as written, doing only what each step says and nothing it leaves out.
  4. When a step is unclear or missing, stop and act it out literally so the gap is obvious, then let your child fix that step.
  5. Run the improved instructions again and see how much closer the result gets.

What you need

  • Task materials
  • Paper and pen
  • Allergen flag

Make it yours

Younger, 9-10 years: Choose a very short task and let them say the steps aloud while you write them down. Older, 12 years and up: Add loops and choices in plain words, such as repeat until done or if it is too tall then remove one block. Siblings: One writes the steps and the other follows them literally, then they swap roles.
