Others will doubtless have great suggestions...I have had good experiences with Singapore Math with my own visual learner with dysgraphic/dyslexic tendencies. I will say that I tead-aloud and scribed work through the first five levels of SM. While there is significant emphasis on word problems (as application and problem solving), you don't have to write about them, just read them and do the math. Math Mammoth has a lot of overlap in the concrete-pictorial instructional approach, but a lot more problems (you don't have to do them all, of course), and the advantage of being a relatively inexpensive set of printable texts. But we homeschool, so we don't have to deal with conflicting or poorly-matched instructional methods, and SM is our math curriculum, not a supplement.
If you are looking for a substitute for the school curriculum, to be implemented by the classroom teacher, Math In Focus is the Houghton Mifflin Harcourt version of essentially the same process, but laid out in a style that will be more familiar to a North American-trained public school teacher. Given the differences in pedagogical approach, if I were going to have a teacher do this instead of myself, I would lean toward the HMH version, as it has better teacher support, and thus a higher likelihood of implementation fidelity. Plus, the school might already have an account with Harcourt, which might give them access to institutional pricing. And, I just noticed that they have an eText for iPad.
