2.2 lesson 13:
​functions


In this LESSON you will learn about:

Learning Objectives:


  • what a Function is   
  • the usefulness of functions in coding
  • ​how to create a Function in Python

  1. ​​​​define what a Function is and why it is used
  2. demonstrate an ability to create Functions with code.

Lesson Overview 

Resources


Starter:
Begin with this online Python Function Quiz

Main:
This lesson is about Functions.  These are lines of reusable code that can be called or re used at any point in the program without having to type out the lines of code again.  In Python a Function is created using the code def name_of_function():

  1. Teacher introduces what Functions are 
  2. Students work through online tutorial 
  3. ​Use class notes to re-cap / teach Function content and examples
  4. Video can be used a lesson starter or refresher of the concepts
  5. Students work through the worksheets activities.  These can then be peer assessed or marked as a class
  6. Students could work in small groups or peer teach each other.
  7. Complete the online worksheet on Functions
