My catch up plan for my son is Math U See. There are 6 worksheets per lesson. The 1st one will be graded. If he gets 90 percent or higher, he skips to the review worksheet(#4), which is graded. If 90 on that, he moves to the test. Hopefully, he will be highly motivated to pay close attention and score well. If your son prefers books vs. the video you or he could read the lessons in the teacher’s manual.
My son is using LOF for Algebra now, but is running out of time. I am unsure how to tweak it. He used LOF for pre algebra and Algebra and decided that he prefers just the math vs. the stories.
My younger son, avid reader, prefers LOF.
Both are taking longer with Algebra than planned. I also got Algebra help books from the library, and use purplemath.com
Even for my struggling learners I require Algebra, geometry, and consumer math.
