McKeague and Pawlik Textbook Homework

Textbook problems are a great way to start practicing new math skills. Build the habit of asking yourself if each answer you get is reasonable. Check your answers so you do not practice bad habits.

While you do these problems, review your own notes. Where are they missing an example problem? Where can you improve an explanation? Fix up any weak spots in your notes. Make flashcards if those help you.

This page has a list of recommended odd-numbered textbook problems. This list is designed for a hypothetical student with a "typical" math background. If your math foundation is weak, do even more odd-numbered problems. If your math foundation is strong, do fewer.

These odd-numbered textbook problems have an answer key. Find it by clicking on "Supplements" on the right side of the screen, and then picking "Selective Answers".

If possible, do homework with others. Students who participate in study groups almost always pass the class. You can ask your instructor to help students find study groups.
