Everyone should start with Volume 1, unless they can add, subtract, multiply, and divide really well, even with a decimal point.  

The first four Volumes can be completed in about four months.  The last three high school Volumes take about three months each to complete for a total of one and half years.

Yes, but it may take a year for a younger child to get through the first book.

Yes, there is one worksheet per lesson, chapter tests and a final test in each book.  We offer one additional worksheet per lesson on our website as a pdf for you to print. 

The Book of Worksheets is best suited for younger children.  It contains the same worksheets from Volume 1, the supplemental worksheets from our website, plus a third worksheet for every lesson, review worksheets before the chapter tests and a few bonus worksheets for fun.  Older students can excel in math without this book.

Try the books in your house for 30 days, starting from the date you receive them.  If you aren't learning math, send them back and we'll refund the purchase price, no questions asked. You will have to pay to ship them back, but don't worry less than one-half percent of people return the books.

If your kids can share, then one set will teach them all.  You can write in the books, or you can print the worksheets from our website and keep the books clean.  We have supplemental worksheets there too.

Over the years, we have added lessons and made changes to each of the books resulting in a different edition number.  The most recent change was adding some color ink.  We only sell the most recent editions on our website.  They are:

Volume 1 Fourth Edition

Volume 2 Fourth Edition

Volume 3 Fifth Edition

Volume 4 Fourth Edition

Volume 5 Fourth Edition

Volume 6 Fourth Edition

Volume 7 Third Edition

The earlier editions are 98% the same, but without color ink.  They can be used with newer editions.  

If you bought our books elsewhere, you can purchase the password to access the printable worksheets in our store for $12.00.

The books are shipped from New Hampshire via USPS Media Mail.  It typically takes seven days to arrive to a US address.  If you're in a hurry, try Amazon.com.
