Lesson details

Key learning points

  1. A programming extension can be used to add features.
  2. Real world considerations should inform design choices.
  3. Specific blocks can be chosen to setup a program.

Keywords

  • Extension - an option that adds new features to a Scratch project

  • Setup - a part of a program where the starting instructions are given, such clearing the screen or setting a sprite’s position

Common misconception

The pen down block turns the pen function off.

The pen down block makes the pen draw and is required to make marks on the stage. Pen up allows the sprite to move without making marks on the stage.

Students will set up their projects so that they start in the same way every time they run. This setup process relates to the computing term ‘initialisation’. Initialisation is the process of setting starting values (variables) for a program, so that the program starts in the same way each time.
