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 explain that programs run sequences, which can be triggered by an event.
Key Notes
- A sequence is a pattern or process in which one thing follows another.
- Event blocks are used to trigger a sequence.
- A scratch project can include multiple sprites which are triggered by different events.
- A design is a plan to show how something will look or work.
Vocabulary To Learn
- sequence: the order of commands in a program
- event: an input which triggers a block of commands to be run
- design: a plan for what you want your program to do
Common Mistakes To Avoid
- The order that command blocks are joined together does not make a difference to the outcome.
3 Quick Questions (With Answers)
1. Describe the system or process from this lesson in clear steps.
A sequence is a pattern or process in which one thing follows another. Event blocks are used to trigger a sequence.
2. Define this computing term and give one practical example. 'sequence'
the order of commands in a program. Add one real device or system example to prove understanding.
3. Correct this common computing misconception.
Mistake: The order that command blocks are joined together does not make a difference to the outcome. Correction: The order of a sequence is important. A program will only follow the commands that it is given in the order that they are connected.
