Lesson 11- Variables!!

Reflecting: Design notebook question
What did you like about the maze project? How might you want to change it?

Creating: Maze extensions
· Group into teams of three people.
Check out these Maze extension projects   http://scratch.mit.edu/galleries/view/138300
· Select one of the Maze extension projects to explore:
o   Score: Demonstrates how to set and change a score. Receive 10 points every time the Scratch cat is clicked.
o   Timer: Demonstrates how to use a timer. Use the mouse to navigate the Scratch cat to Gobo.
o   Enemies: Demonstrates how to add an enemy. Avoid the crazy tennis ball using the up and down arrow keys.
o   Levels: Demonstrates how to change levels. Score increases by 1 every time the space bar is pressed. Level increases by 1 for every 10 points.
(Rewards: Demonstrates how to collect items. Use the arrow keys to move the Scratch cat around to collect items for his quest.)

Reflecting: Here’s what I figured out
·  After studying the extension projects, teach the rest of the class what they learned. Take notes to help you explain the processes.
o   What was the project?
o   How could it be used to extend the maze? 

 How does it use variables?

 Notes- Variables are an important mathematical concept and also an important computational concept. You learn about variables in their math & science classes at school, but many have a difficult time learning them. Games are one way to make the usefulness of variables more concrete.
