Coding Unplugged / Algorithm Sandwich

Algorithm Sandwich

Children write precise step-by-step instructions to make a sandwich, then an educator follows them literally.

How to run it

  1. Explain that computers follow instructions exactly.
  2. Have groups write steps to make a sandwich.
  3. An educator follows the steps literally, with funny results.
  4. Groups refine their instructions and try again.

You will need

  • bread
  • spreads

  • plates
  • paper and pencils
Make it easier or harderYounger children use picture steps; older children add loops and conditions.
SafetyCheck allergies and dietary needs and use butter knives only.
My Time Our Place · Outcome 4, Outcome 5Writing precise instructions builds computational thinking and communication.
