๐ What you need
- one shared phone with a browser and a block-coding site (Scratch works in a phone browser; turn it sideways)
- patience with small fingers on a small screen
- your command list from module 1, written down
โ Do this
- Turn the phone sideways. Everything is easier sideways.
- Drag one 'move 10 steps' block under the green flag and tap it. The cat shifts. That tiny movement is your first program running.
- Add 'turn 90 degrees'. Then another move. You are writing exactly the list you shouted in module 1.
- Draw a square path. Four moves, four turns. If your square comes out crooked, check your turn number.
- Now recreate your module 1 water route on the screen, obstacle and all. Draw the bucket as a second sprite.
- Tap the green flag and watch your dust-path from week one run inside a phone.
๐ก Why it works
Nothing new happened here โ that is the lesson. Blocks are just your spoken commands written in a way a machine can obey. This is why doing it with your body first was not a waste of time: you already knew the hard part before you touched the screen.
๐ฅ Challenge
Program a triangle without being told the turn number. Get it wrong, look at the shape, and adjust. That is how real engineers find numbers.
