Since they have accelerated her reading, is it better? I would recommend using after school time to teach all the things that school doesn't believe is needed until 3rd or 4th grade. Science, History, Music etc. How about starting a new language? We have used Rosetta Stone with great success at that age.
Ask your daughter to choose something that interests her, then dive in, dig deeper than you ever thought you could. Ad nauseum, then choose another. There is an old post on here called "learning on a line". Basically it is the willingness to follow wherever the line leads.
An example of this would be studying the Vikings. In addition to the people in general, take your daughter to the kitchen and make a viking meal. Their longboats were 60 feet long. Get a string and measure 60 feet. Look at the propulsion, rowing and have your daughter explore other methods such as sails. Build a sailboat, test drive it in the tub. From there it is a natural jump to wind power which will lead you to alternative fuels ie: solar power..... Follow the line, Wherever!! It's amazing where you will end up and what your daughter will get to explore.
By letting her choose the initial subject, she will be invested in the success of your project. As time goes on, she will become more and more adept and choosing what comes next. The kids love this!
