How many lessons in a "Key To .............." book?

[Suzanne in ABQ]

My 6th grade dd is going to finish Singapore 6B before we're finished with this school year. I'm planning on doing Pre-Algebra (probably Video Text Algebra) next year, but I need to fill up this year with something. I'm considering the "Key To" series, but I don't know how many books to get.

How many lessons are there in each book? Dd is very independent, and enjoys math (but doesn't love it). She's doing well in PM6. How long should I expect each "Key To" book to take?

I have all four of the decimal books in front of me. Each book has 44 pages. They are not broken down into lessons. We just used them to supplement, and I would have ds do 2 to 4 pages per day depending how many problems were on a page. These books are very easy to use and understand and I will probably use them again with my younger ds.

HTH,

Okay, so my dd (who already understands the material) could probably do 4 pages a day as review. That would be about two weeks per book.

Thanks! That helps a lot.
