2. Checking your Algorithm
Go to the following link (Same on as on the PowerPoint from Monday)
Use this website to test your algorithm
If it works have your neighbor test it, sign it off and turn it in.

3. Learning Objectives
To learn about Event Handlers by programming scripts that are triggered by input from the computer keyboard.
