I love this type of quiz. Students have 3 chances to make 100%. I gave quiz #1, graded and then returned it to the kids quickly. We then had a quick discussion hoping to fix any problems.
If students made a 100% on the quiz #1 - quiz #2 and quiz #3 will count as bonus points
If students made below 100% on quiz #1 they will get 2 more chance to make 100%
I record the highest score. After 3 chances if a students has not made 100%, I assigned the following problems for homework. These problems have the answers already given. I think this is helpful so the kids can work the problem and try to get the answer given. If they don't they need to rework the problem until they do.
