I have used "Teach your child to read in 100 easy lessons" its ok, it does work... but *I* was board out of my mind! I switched to Hooked on Phonics and my kids love it!
I also use all about spelling after they are reading at a kinder level (so about 1st grade). There is also an "All About Reading" curriculum that looks fantastic too, Its newer, and I haven't seen/used it yet, but the reviews are great!
For math I use Math U See, Love it! I have used Saxon, it was good, but also boring for both the kids and me. Its meant to be used every school day, and while you can tailor it to what you need, that was requiring more effort then I wanted to put into it. It was better when I was only teaching 1 child and 1 grade... But the way Math U See is, I can do the lesson, leave that child to work on the practice problems, work with the other child on something like reading, then come back to the 1st... With Saxon I needed to be present the entire time, which just isn't happening in our home right now.
Handwritting with out tears is also great, we usually only use it for Kinder, but I think when I introduce cursive I'll go back to their material!
For Science, history/social studies we still just use the library and field trips for what they are into... nothing formal. If you want something more formal for Science I love the Apologia Stuff! I have some waiting for when we want more structure. And History, I like the "Story of the World" It teaches chronologically, and repeats every 4 years, and can be used with multiple grade levels.
We also do lots of Language arts Lap books, that you can find free all over the web...
I like piecing things together individually, I find its more affordable to make changes when something or a subject isn't working vs a 'boxed' set. It is a bit much to look at all the pieces individually, but for me it works better. I've made a lot more adjustments then I ever imagined so Im glad I went this rout.
Also Confessions of a Homeschooler has ALOT of stuff for preK and Kinder at very affordable prices, and its great stuff! She also reviews lots of different pieces (Saxon, Math U See, All About Spelling/Reading etc... she also links to reviews from other bloggers).
