17. Algorithm
An algorithm has to be written so that it can be followed exactly.

18. Your turn!
Draw a robot using triangles, rectangles, squares and circles - keep it secret!
Write an algorithm for your friend to follow to draw the same robot
Does your friend's robot look like yours?

19. My robot algorithm by
Algorithm followed by

20. Improve your algorithm
Now improve your algorithm and let another friend follow it
Does the robot look more like yours?
