Unit Summary
In this unit, pupils explore the link between events and actions. Pupils begin by moving a sprite in four directions (up, down, left, and right) and then explore movement within the context of a maze. This unit also introduces programming extensions, through the use of Pen blocks.
Lesson Summary
You will learn to create a program to move a sprite in four directions.
Key Notes
- A program can be written to move a sprite in four directions.
- The size of a sprite may need to be adjusted depending on the background.
- Algorithms can be translated into code.
- Code can be adapted by duplicating and changing the values.
Vocabulary To Learn
- algorithm: a precise set of ordered steps which can be followed by a human or a computer to do a task
- sprite: a graphic object that can be controlled by a program
- duplicate: to copy an exact part of a coding project
Common Mistakes To Avoid
- The size of the sprite doesn't matter when programming movement.
3 Quick Questions (With Answers)
1. Describe the system or process from this lesson in clear steps.
A program can be written to move a sprite in four directions. The size of a sprite may need to be adjusted depending on the background.
2. Define this computing term and give one practical example. 'algorithm'
a precise set of ordered steps which can be followed by a human or a computer to do a task. Add one real device or system example to prove understanding.
3. Correct this common computing misconception.
Mistake: The size of the sprite doesn't matter when programming movement. Correction: Sprite size is important, especially in a maze, as if the sprite is too big it will touch the walls.
