Abeka 10th Grade 10–Biology, World History, & Algebra I Teacher’s Editions/Key/Video Manuals +Bonus+2 slightly used student Lab manualsBiology-Teacher EditionBiology-Test KeyBiology-Quiz KeyBiology-2 Student Lab books. One has the back cover cut off (not sure why–came that way to me). Both of these have 12-30 pages used in them. So, I am adding them as bonus books. I think they are still very usable, but just want to share info. Algebra I-Video ManualAlgebra I-Test KeyAlgebra I-Quiz Key World History-Video ManualWorld History-Teacher GuideWorld History-Test/Map Key All books show some shelf wear. Please look at all pictures as part of the description. Other than the writing mentioned in the student Lab books, a quick flip through of the other books show little to writing or marks. The SECRET SAUCE of eBay: POSITIVE feedback is very important to me. It truly does help keep the endeavor going!! I am not a business. I am truly just a MOM going through the never-ending things that seem to accumulate over the years. I am tired of doing “yard sales”– so eBay has been a good way for me to downsize the closets. I try very hard to describe things to the best that I see them. Please ask any and all questions. Remember, what I may not think is something important to mention–you may think it is very important and therefore could be for someone else. So, it is a good way for all of us to learn. 🙂 Respectfully, please contact me first if there is every any issue with a purchase. THANK YOU in advance for your business and POSITIVE FEEDBACK. I will do the same for you. Angela 🙂
