π Understanding Sequencing in Scratch Jr.
Sequencing in Scratch Jr. is like lining up dominoes. Each action happens one after the other, in a specific order. Imagine telling a character to say 'Stay', then 'Safe'. Sequencing ensures they say 'Stay' before they say 'Safe'. This creates a clear, step-by-step narrative.
𧩠Understanding Parallel Blocks in Scratch Jr.
Parallel blocks are like having multiple things happen at the same time! π― Imagine your character waving and saying 'Hello' simultaneously. Parallel blocks allow you to start multiple actions with one trigger. This is great for creating more complex and dynamic actions.
