Lesson details

Key learning points

  1. Programs can be created based on designs.
  2. A project can contain multiple sprites each with separate sequences of code blocks.
  3. An algorithm is a defined sequence that can be followed and represented in code.

Keywords

  • Design - a plan for what you want your program to do

  • Test - to run a program, looking for any errors

Common misconception

Once the project has been programmed, it's finished.

It's important to test and debug to make sure the project works as intended. Look back at what was set as to what would make the project a success and consider how well the pogram carries out the task.


To help you plan your year 3 computing lesson on: Creating a maze project, download all teaching resources for free and adapt to suit your pupils' needs...

This lesson lets you assess how effectively the students complete their designs. Can they realistically create projects based on their designs? As a minimum, their designs should include algorithms for each process associated with the sprite, and be clear on the artwork for the sprite and the stage.
