After you've had your fun, head to the evaluation tab to find out how you will get your grade for this activity.

Evaluation

You will be graded for participation based on your worksheet, which you will turn in to Ms. Svajda.  You will also create a short, reasonable quiz with an answer key to help show Ms. Svajda how much you have learned.  You will write this quiz using a word processing software and you can either email it to Ms. Svajda or you can print it off and submit a hard copy.

Your quiz must be at least 5 questions, have both addition and subtraction questions, and be something that would be fair to give to your classmates.  Not too hard, but not too easy.  Somewhere right in the middle.  It's your chance to pretend you're the teacher.
