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