These satisfy the hardtomeet curriculum needs for students who don't easily fit into a regular school program or have special learning difficulties. Key to... workbooks offer a positive alternative to large, expensive textbooks, which students often find complicated and intimidating.
Only one concept is presented per page, so students have time to understand new ideas without being overwhelmed. Handwritten examples and exercises make work seem less intimidating. Vocabulary and reading level are simple. Instructions are clear and direct, so students can work alone or in small groupsgiving you more time with those who need extra help.
Save Your Valuable Time
Each book is a complete text/workbook. You don't have to prepare lessons, duplicate pages
of problems, or make answer keys or problems sets. Answer books provide actual
reproductions of each workbook page and show every solution stepbystep. Support
materials also include helpful suggestions for using the workbooks with your class, class
progress charts, and reproducible diagnostic and final tests.
Stretch Your Budget with Affordable Low Prices
The extremely low price of these workbooks means each student can have his or her own
personal workbook. Also, whenever necessary, you can replace a lost workbook for a
small fraction of the price of buying a new textbook. You can use these as supplemental
materials to your regular math curriculum when a student needs help with a concept that's
especially challenging to him/her.

They can use graphing calculators, electronic datagathering devices, and dynamic geometry software, when available, to investigate functions, continuity, critical points, and limits. Many activities are appropriate as group investigations, and students learn how to present results in a lab report format.
Also included in the book are 11 writing assignments that encourage students to think about the way in which calculus and precalculus concepts relate to their lives and the world around them.
