Algebra 2 Midterm Review Guide
To prepare for your midterm exam, please follow these suggested steps. The more
practice you do, the better prepared you will be for the exam. Be sure to have your
calculator ready the day of the exam with WORKING batteries, a straightedge, and
more than one sharpened pencil. Do not expect to borrow materials.
1. Review key vocabulary terms at the beginning of each chapter or use the list at the end
of the chapter in the review.
2. Read the chapter summary at the end of each chapter several times. Write down any
ideas that are unclear.
3. Review the quizzes and tests you have already taken and be sure that you would get
100% if you took the same test today.
4. Complete the lesson-by-lesson review in the Study Guide and Review section at the
end of each chapter.
5. Complete the practice test at the end of each chapter.
6. Use pages 947-960, 965 for extra practice problems for each section of each
chapter. This is the EXTRA PRACTICE section of the back of your book.
7. Use pages 979-984 for extra practice word problems for each section of each
chapter. This is the MIXED PROBLEM SOLVING section of the back of your book.
8. For additional practice on areas you may use previous homework assignments. Your
homework should be a solution key to check your work.
9. Use the guiding questions in the remainder of this packet for a general review. However,
do not rely solely on these questions.
*REMINDER: Bring all quizzes and tests to the exam for extra credit on the midterm!!
You must have all of them or no credit.
