3. Now, you can go back to the textbook pages and try the exercises, review, and practice. The answer sheet is at the end of the pages. 

4. If you would like extra practice, go to the Math Antics Homepage link, and scroll down to where it says "Multiplying and Dividing Integers". There you will find more exercises and worksheets. These all have answer keys.

5. There is extra review and practice on math.com (linked to the right), and Khan Academy lessons.

6. Play the Math Games involving integers to test your knowledge.
