I did not have mine skip PreAlg.from TT7. She did skip some problem sets in early chapters. Ihave both TT PreAlg and TT Alg complete sets good condition w/ no writing in books. If anyone is interested. Asking $149ppd or $80each.

If you are looking I have both complete sets of TT PreAlgebra and TT Algebra for sale. Good condition.$149ppd for both or $80 ppd each.

Love Teaching Textbooks.Love this program for afterschool and math gaps or honing in on skills.You can use Chapter Test to assess before beginning each Chapter to determine if you need to review that material. Each lesson takes roughly 25-30 minutes. Cannot speak highly enough about this program. Ihave both PreAlg and Alg I complete set that I am getting ready to sell thatI have not posted for sale yet.If someone is interested will sell both for $154ppd paypal accepted. afterschool and math gaps.

I have choosen not to skip levels and very glad that I made that decision.This past year and half, my DD finished TT5,TT6 and TT7. I had thought about skipping TT7 and am very glad that we didn't. TT7 problems are more difficult than TT6 include factoring fraction and has a geometry unit. I think it would have been to much of a jump from TT5 to TT7. We own Pre-Alg and Alg I . And I think it would be to much of a jump to go from TT7 to Alg. I We are going to start Pre-Alg. this fall. I would rather have a child move quickly through material that came easy and be able to slow down on math strands that are not secure. Plus TT has a great resale valve. Hope this helps you, plaa
