Lesson Details
Key learning points
- Pen blocks, such as pen up, change pen colour, and change pen size, have specific functions that can be predicted.
- Suitable keys can be assigned to trigger additional features.
- New features can be added to existing projects by using a design plan.
- Sequences of commands can be built to make a design work.
Common misconception
Pen up and erase all do the same thing.
Pen up stops the sprite from drawing a line, erase all clears all lines already drawn. Pen up stops new marks being drawn on the screen but keeps what is already there whilst erase all clears everything that already exists.
