It is overwhelming!! My daughter, although still young, doesn’t grasp math easily and I’m trying to find a program that will work well for her.
I really like the spiral approach, but my two who use TT are quite good at math, so I can’t speak to how it would work with someone who struggles with math. My kids use just the CDs with scrap paper.
Have you tried the sample lessons on TT? And the placement test? My 8YO is working on TT4 and my 12YO has been working on PreAlgebra for almost a year. I wonder if TT4 might be too easy for your 10YO. In my experience, the grade level on TT tends to be about a year behind public school.
