Making the Cat Walk

This is the first lesson I give to classes learning Scratch.  After giving a tour of the Scratch interface, I ask them to start building this script with me.  In doing so, they get a quick demonstration of creating new costumes, the importance of positive and negative variables, the existence of the x/y grid, and timing.  After building the first part of the script, I ask them to complete it by making the cat turn in the opposite direction and “walk” back across the stage.

Copy this script.

Scratch1

How can you make the Sprite turn around and walk back across the screen?    Write your thoughts about this below.  Then try to accomplish the task.  Write about your results, even if you were not successful.  We learn from trying.  Each version of the task is called an iteration.

Experiment with the blocks below.
