Hi Zamommy4,
Welcome to the forum. It's normal to feel overwhelmed as there are so many options on the market to teach our LOs. I've been here on the forum for about 4 years and I still feel the same. LOL
For math, I would suggest you read math and toddler threads. The most popular programs are RightStart Math, Singapore Math, MEP (free), Life of Fred, etc. I would recommend you visit their websites and see which one fits your learning style the best. You can also a combination of programs to get the most of them.
For math facts, you may just play games (as in RightStart math), you can also use the SpalshMath app, Gigglemath.com material, or 2 plus 2 is not 5 book.
For handwriting I highly recommend handwriting without tears as it is a multisensory program.
For reading, we LOVE readingbear.org
For more advanced reading instructions, you can use the last chapters of Ordinary Parent Guide here:
