Lesson details

Key learning points

  1. Computers only follow the commands they are given, so these need to be precise and accurate.
  2. Commands can be joined together to create sequences in Scratch to achieve a desired outcome.
  3. Sequences can be separated into individual subroutines.
  4. Programs should be written so that other people can easily understand them. Subroutines are used to do this.

Keywords

  • Execute - to run or carry out the commands in a program

  • Sequence - the order of commands in a program

  • Subroutine - a named sequence of commands used to perform a specific task within a program

Common misconception

A sprite in Scratch can only have one sequence of code blocks.

Sequences of code can be separated into subroutines and these subroutines can be called multiple times.

'Acting out' instructions is helpful for pupils to understand the logic of any algorithm. Encourage pupils to imagine that they are the objects they need to control. By doing so, they can better appreciate what commands are needed to carry out required actions.
