Study Guides
This pupil-friendly study guide includes a unit summary, clear notes, common mistakes, and quick questions with answers.
Unit Summary
In this unit, pupils will explore the concept of repetition in programming in the Scratch environment. Pupils will look at the difference between count-controlled and infinite loops. They will use their knowledge to modify, design and create games and animations that involve repetition.
Lesson Summary
You will learn to develop a design that includes two or more loops.
Key Notes
- Two or more loops can run at the same time.
- Repetition can be used to animate a sprite by changing its costumes.
- An event block, like the green flag, can start multiple processes simultaneously.
Vocabulary To Learn
- animate: to make something move or change its appearance
- algorithm: a precise sequence of steps that can be followed to do a task
- duplicate: to copy something exactly, such as part of a coding project
- evaluate: to look at something carefully and decide how well it works or how it could be improved
Common Mistakes To Avoid
- You have to make each letter start animating one after another after the green flag is pressed.
3 Quick Questions (With Answers)
1. Describe the system or process from this lesson in clear steps.
Two or more loops can run at the same time. Repetition can be used to animate a sprite by changing its costumes.
2. Define this computing term and give one practical example. 'animate'
to make something move or change its appearance. Add one real device or system example to prove understanding.
3. Correct this common computing misconception.
Mistake: You have to make each letter start animating one after another after the green flag is pressed. Correction: When you press the green flag (or another event block), you can make two or more sprites start animating at the same time.
