In this LESSON you will learn about:

Learning Objectives:
How to interpret and understand an algorithm using a Trace Table to identify what the outcome of the algorithm is and its function.
  1. Know the role of a Trace Table
  2. Understand how to interpret code and create a Trace Table
  3. Use a Trace Table

Lesson Overview 

Resources
Starter:
The Friendship Algorithm 
Look at the Friendship Algorithm
Can you run through the algorithm and discover you outcome?

​Main:
  1. Copy down the Teacher notes from the lesson presentation
  2. Work through the first Trace Table example, copy into your book
  3. Share your results / outcomes
  4. Try the second example independently
  5. Team up with another student and share outcomes, make corrections.
  6. Teacher / class check results.
  7. Work through Worksheet 1, (complete a question then share results)
 
​​​Plenary:​​
  • Play a suitable Kahoot
  • Students create their own algorithm and ask another student to follow it, creating a Trace Table.
