This test contains 37 multiple choice questions on topics presented in my Algebra Guided Presentation Notes: Unit 7 - Exponent Rules, which is available here on TPT. This is a PDF file, but if you would like it in a word document, I will be happy to e-mail that to you after purchase. This would also make an excellent review on exponent rules before the state test.
Also included, the answer key, and an answer document for students in case your school doesn't have a scantron machine.
Don't let students actually write on the test. Have them use scratch paper and record their final answer on an answer document. Require students to turn in their scratch paper with the test. (I never grade scratch paper, but requiring students to turn it in keeps them from taking your test questions from the room or sharing with others.)
A Word About Multiple Choice Tests:
There are many teachers who have strong opinions against multiple choice tests for math. I too was on the fence on this one and for many years I gave "show your work" test and gave partial credit. I learned four important lessons during those years. First, that the quality of the test really matters, distractors must be really good and answers that would follow from common errors. Second, that once the test was that good, the students performed exactly the same given either kind of test (trust me, I gave two parts, one multiple choice and one show your work, and it didn't matter). Third, that students exposed to multiple choice tests during the year tend to have less test stress during state testing time. And finally, that I was a much happier and more positive teacher when I didn't have to spend my entire weekend grading tests!
