My dd is 4.5 and this is what we are doing slowly and will continue it.
Reading: I started with 100 easy lessons, she knew her letters and sounds from the letter factory and other things. She didn't like 100 easy lessons and dreaded reading, so I shelved it and we are starting IEW PAL program after the new year, I think she will love it!
Writing: we did get HWT get set for school and she learned capital letters and numbers but we are moving to IEW PAL writing after the new year and the letter stories with their sound and how to write the letters have really helped her craft better letters.
Math: mus primer, we are about half way through will cover to alpha when we get there.
We also do classical conversations and I love it, so does my dd. She is hanging a lot of memory pegs and is really connecting the dots on something's. I use cc as a direction to go, we supplemented with picture books this year for history.
Some things I am gong to add next year is reading along story of the world and something for science, maybe the library and videos for science.
