DS11 is finishing Beast 5, after having completed Singapore 5 last year. He would technically be a 5th grader, but I have him as a 6th grader.
He is math intuitive and has always excelled in all areas of math. I purchased AOPS Pre-Alg last spring, anticipating he would start it this winter. But, he's had some difficulty with some of the more advanced concepts in Beast 5 (usually with the challenge sections...he does well in the rest), so I have decided to hold off on AOPS until later this spring.
But I can't shake the feeling that AOPS Pre-Alg might be a miss for him. So of course, here I am on the hive and...so many other options! LOL!
Any other suggestions on a Pre-Alg program that's engaging, affordable, and solid? AOPS Pre-Alg is just so boring and dry.
