We all need to mix up to motivate sometimes and scratch off answer keys are a sure fire way to get every student in your class thinking harder, no matter what content you are assessing. Students who always do well love the instant feedback, and students who often struggle rejoice at having second chance. By using scratch off answer keys, student motivation is high, grading is done for you, and cycling back to student need is easier than ever because learning isn't done until they've figured out the correct solution.
I always love adding a twist to standardized assessments (and independent/group review!) and I have found that scratch offs never cease to be a hit with my kids. However, I found it difficult to do them more than once or twice a year because it takes a while to make them. Now with these templates, I can have them all pre-made and just tweak my answer key to match; assembly line efficiency means more time for the important stuff!
*These are just templates, you will need to download and then use either of the suggested ways to make them scratch off - purchase stickers or DIY.*
