Instead of worksheets, have you tried just showing her the concepts in real life and focusing on mental math? Fractions in your recipes and geometry in household objects? Decimals on your grocery shopping trip? The beauty of elementary school math is that it is so accessible and intuitive and prevalent in every day life. If you were to use the standard pre-written stuff, couldn't you just read it to her and accept her verbal responses?
Just the idea of even a second grade math curriculum (much less third grade) without reading and writing is so foreign in our school district! There has been such a shift towards verbalizing math that even in second grade, the students are required to explain their math answers in words at least some of the time. Even simple arithmetic problems in second grade (and some in first grade) tend to involve reading a couple of sentences even when an explanation is not required in the answer. It seems so wrong to me and likely to preclude many mathematically talented students from participating in the more advanced math programs in the early elementary years.
