This session introduces the concept of variables through the specific example of keeping score in a game. The key concepts of variables in Scratch are explored using a simple game.
How is it tailored for 5-7 year olds?
- The general concept of variables is not developed, rather a readily understandable use case is employed
- Similarly with negative numbers, the specific use case is described (a way to make the score smaller) rather than the general concept
- The game purposely starts in a very simple form that isolates the use of variables, but has many incremental improvements to suit a wide variety of ability
What is covered ?
- Variables through a simple game
