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 design a project that includes repetition.
Key Notes
- An algorithm can include repetition.
- Key parts of a given project can be selected to use in your own design.
Vocabulary To Learn
- repetition: a part of a program where one or more commands are run multiple times in a loop
- algorithm: a precise sequence of steps that can be followed to do a task
Common Mistakes To Avoid
- You only need to program one loop for a whole game.
3 Quick Questions (With Answers)
1. Describe the system or process from this lesson in clear steps.
An algorithm can include repetition. Key parts of a given project can be selected to use in your own design.
2. Define this computing term and give one practical example. 'repetition'
a part of a program where one or more commands are run multiple times in a loop. Add one real device or system example to prove understanding.
3. Correct this common computing misconception.
Mistake: You only need to program one loop for a whole game. Correction: Each sprite needs its own loop so it can repeat its actions independently.
