Hi M..
I home schooled both my boys from preschool. They are now in 5th and 2nd grade. The curriculum I started with is "Sing, Spell, Read and Write." You can find it online, or email me if you can't and I'll look up the publisher for you. There is a cost involved, but it sounds like what your daughter might enjoy. You get CDs with music that teach the alphabet, short and long vowel sounds, and then many other tools for learning to read and write. It is fun because it is learned through song, but it is meant for preschool through 3rd grade, so it is a good investment. There are also workbooks to practice writing, plus cut and paste, etc. I highly recommend it.
Also, since she loves song and activity, go for lots of walks and teach her through nature. Count your steps, add brown leaves and yellow leaves, go to grocery stores and add apples and oranges, etc. At her age, learning can be lots of fun. There are also tons of free printables online. Just google "free preschool curriculum" and you should be able to find lots.
My boys are completely different in their learning styles, but that is the great thing about home schooling. You can work with each in their own "language." My oldest started reading in preschool, my youngest didn't even grasp the alphabet until 1st grade, but he now reads better than his older brother. No worries. They all eventually get it. Good luck to you and God bless your family.
