Five in a Row and Sonlight too!

I don't know if this is what you are looking for, but I recently found Power Basics which isn't labeled by individual grade level. It's actually labeled 6th - 12th with a reading level of about 4th - 5th. I am hoping this will be perfect for my son, who is a behind and a struggling reader. I just ordered a bunch from Rainbow and as soon as it arrives he will be using Power Basics Basic Math (followed by Consumer Math), Basic English, World History 1, Earth and Space Science, and Vocabulary and Reading Comprehension You can find samples at Rainbow Resource and CBD. For Spelling I'm going with Spellwell because I like that it isn't graded either (just labeled A, Aa, B, Bb, etc).

This is really great. I am sitting here researching every one of these and finding many options I did not even know about.Thank you all so much.Keep them coming.

www.rainbowresource.com

is a great place to find a lot of these
curriculums and most of their products
have sample pages for you to see.

I just came across these two for math:
www.systemath.com and Practical Arithmetics
You can see samples of Practical Arithmetics at Christian Books (they have great sample pages of most of their items : )
