Lesson details
Key learning points
- Each sprite can have its own sound.
- The order of a sequence is important to achieve the intended outcome.
- Sound blocks can be used to play more than one note or sound at the same time.
Keywords
Order - the way things are arranged in a sequence
Notes - the duration and pitch of a sound
Chord - two or more notes played together at the same time
Common misconception
The order of a sequence in a program doesn't matter.
A computer will only follow the directions it is given. A program will follow the sequence it is given and the sequence will affect the output, even if this output is incorrect.
Pupils were introduced to the concept of sequences in the previous lesson. Recall this information and get pupils to reflect on what would happen if the order of a sequence was different. In some sequences this isn't vital but in others it can mean the outcome is not as expected.
Teacher tip
Equipment
All pupils require access to devices that have or can access the online version of Scratch. Starter programs are linked to the lesson and can be remixed as required.
