Unit Summary
This unit explores the concept of sequencing in programming. Pupils will be introduced to a selection of motion, sound, and event blocks which they will use to create their own programs, featuring sequences. Pupils will make a representation of a piano where they will explore sequence through sound.
Lesson Summary
You will learn to recognise that the order of commands in a program can affect the output.
Key Notes
- 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.
Vocabulary To Learn
- 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 Mistakes To Avoid
- The order of a sequence in a program doesn't matter.
3 Quick Questions (With Answers)
1. Describe the system or process from this lesson in clear steps.
Each sprite can have its own sound. The order of a sequence is important to achieve the intended outcome.
2. Define this computing term and give one practical example. 'order'
the way things are arranged in a sequence. Add one real device or system example to prove understanding.
3. Correct this common computing misconception.
Mistake: The order of a sequence in a program doesn't matter. Correction: 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.
