Teaching Textbooks - Prealgebra book necessary?

[Tohru]

I'm exchanging TT7 for Pre-Algebra. My son didn't use the book for TT7 at all because he just entered in the answers on the computer.

 

So, since it is about a $70 difference to not get the workbook, I was thinking of just getting the pre-algebra disks.

 

When I told the lady that I wanted to exchange for just the Pre-Algebra disks, she told me that there is a big difference between the 2 levels and I would definitely need the workbook for Pre-Algebra because you can't just enter in the answers like in TT7.

 

Is this true?

 

If you're children used Pre-Algebra or Algebra, did they actually use or need the workbook?

 

Thanks!

Yup, there is a big change between elementary and the upper levels. For TT Pre-Algebra one watches the lesson on the Lecture and Practice CDs then does the problem sets in the workbook. Since the entire lesson is printed in the workbook, I know some kids, including my own the last few weeks, that just skip the computer step altogether. It also comes with a Solutions CD and a Test Solutions CD, but so far I've just explained errors to ds as I marked them.

You need the workbook because that's where the problem sets are. But if you want to save money, you can have your DS work the problems on a separate paper (there are only around 20 problems per set), and then resell the workbook with the disks when you're done.
