Algorithms 2: Algorithms Unplugged

< Back to Building Block


In this project, you will write an algorithm (a set of instructions) then use a set of symbols to create a flowchart. (estimated 30 min)

Learning Objectives

By the end of this activity, participants will be able to...

  • Construct an algorithm using a constrained number of commands
  • Translate algorithm into a flowchart as a blueprint to solve a problem
  • Compare a computer’s capacity to follow an algorithm to a human’s capacity to do so


    • Algorithm: a step-by-step set of instructions
    • Flowchart: a diagram that visually presents the sequence of steps (flow of data) through a procedure or program (processing system)

    Materials and Resources

    • Scrap paper
    • Pen or pencil
    • Post-it notes (optional)
