Pre-algebra homeschooling book, in good condition, & no missing pages!

Pre-algebra homeschool book, in good condition, no missing pages, and from a clean and smoke-free home! This is a great book if you want to avoid the ridiculousness of common core. *I’m only selling because it’s no longer needed, as my 8th grader is currently doing HS trigonometry, and my youngest has a different learning style.
