This week, our lead mentor was Martha Madden, who blogs at kidswithskills.wordpress.com.

The challenge was to develop a game with a PacMan character, controlled by the mouse, who has to catch ghosts that move at random.

Coding concepts that we discussed included:

1. Design of programs
2. Loops
3. Decisions
4. Using the Paint Editor in Scratch

Here are the notes from the day (PDF): CDA-S2-Challenge04-GhostCatcher.pdf
