Sunshine Math will probably be insufficient for your daughter-- it's fairly small amounts of problem solving that aren't very difficult, and teachers tend to use it to stuff children in the corner with worksheets. What your daughter most likely needs is to be taught to her proper level of understanding and ability, not taught based on her age with some extra worksheets. In other words, if she's mastered single-digit addition, no amount of single-digit addition with extra worksheets is appropriate.
