This pupil-friendly study guide includes a unit summary, clear notes, common mistakes, and quick questions with answers.
Unit Summary
In this unit pupils are introduced to on-screen programming through ScratchJr. Pupils will explore the way a project looks onscreen by investigating sprites and backgrounds. They will use programming blocks to use, modify, and create programs that move objects.
Lesson Summary
You will learn to change the value in a command block and explain its effect.
Key Notes
- Some command blocks can have number values on them.
- Values can be changed, causing different effects.
- Programs can be made shorter by deleting blocks and changing values.
Vocabulary To Learn
- delete: to remove something on a screen
- value: a number that can be changed
- effect: the result of changing something
Common Mistakes To Avoid
- The value is always how many times the command should run.
3 Quick Questions (With Answers)
1. Describe the system or process from this lesson in clear steps.
Some command blocks can have number values on them. Values can be changed, causing different effects.
2. Define this computing term and give one practical example. 'delete'
to remove something on a screen. Add one real device or system example to prove understanding.
3. Correct this common computing misconception.
Mistake: The value is always how many times the command should run. Correction: Different values cause different effects depending on the underlying command. These might not always be numerical values either.
