Please consider making your own curricula. You can customize and make changes as needed. If you have never done this before - have no fear - you will discover it is well worth the effort and the effort becomes joyful. Try using some of the books that have proven to be excellent in the past such as the Saxon Math. There used to be a great book titled “home school your child for free” that had so many websites for just about any subject. I would have used the Khan academy for supportive science and math perhaps if I felt it was needed.
Reading this thread just made me realize something.
My mother is a retired teacher with tons of experience from elementary to teenage and normal and special kids. History, English and Math. She is very conservative. Doesn’t go in for all the BS for “educating” and special education that’s been the rave for 20+ years.
Just the other day she pointed out some workbooks she’s had a while that she loves for math and reading. I also remember well several of her most beloved companies for various texts.
She should’ve made a small business of giving out advice on curricula, including what companies to pick and choose from.
