I have an Algebra 1/2 Teachers Textbook. It is exactly the same as the Student textbook but the answers are all in the back. I don't need paid for it, I am happy to give it away if you pay for shipping. it is the original Saxon.
If you need to create tests you can do so at
http://www.jmap.org/JMAP_WORKSHEET_GENERATOR_FILES.htm . You have to download the software and then install Saxon files separately. Normally Saxon will test on lesson 10 for lessons 1-5. So you are always 5 lessons behind. But it will test on anything that came before that.
The information on the JMAP site is great for Middle and High School. I probably should post it in another thread.
