Order Matters: Comparing Sequence and Random Actions

Overview

Students explore how following steps in the correct order leads to success, while random actions do not.

Learning Objective
Students understand the importance of sequence by comparing ordered and random instructions.

Resources needed

  • No materials required
  • Optional: simple tasks

More information

Teach: sequence, order, random, step, correct. Use frames: 'This works because…'.

Use movement instead of writing.

Can students explain why sequence matters? Can they create correct sequences?

Fully unplugged.

Students may think order does not affect results.

Sequencing is fundamental to algorithms and programming.
