Quick and easy to use, this set of 20 exit slips will help you evaluate your students as they learn PEMDAS. There are 4 exit slips to a page, just cut into fourths and you are ready to go. The first few pages are quite simple and progress to more difficult and rigorous problems involving exponents, parentheses, braces, and brackets. Exit slips are a great way to assess your students to see if they are ready for the next step, or whether they are ready for a more formal assessment. Answer key included.
