Programming 1: Scratch: Pixels and positions

Pupils will be able to:

• Explain that digital visuals are measured in pixels and that computers use x and y coordinates to describe position.
• Use coordinates in Scratch to place and move sprites accurately.
• Understand that rotations and turns are described in degrees and use this to control movement and create repeating patterns.
• Design and code a game that uses pixels, coordinates and degrees to control movement.
• Use nested loops to make code more efficient and recognise when loops need an end to avoid errors.
• Experiment with and adapt code during testing to improve and enhance a game.
• Systematically test, identify and fix bugs in programs, explaining what they changed and why.
• Evaluate their finished Scratch project and describe how it meets its purpose.

Here are some examples of our work.
