I found a really good book for trying to teach your children to learn letters/the alphabet. It seems montessori aligned and provides worksheets and activities covering each letter.

The activities that come with each letter are divided into a math activity, craft, game, movement, snack and literature.

I've noticed a few women in here who are yet to marry/have had bad experiences in the past. Right before I found my children's father, I read this book, and it helped clarify how to look for a good lifelong partner. I don't condone the author; he's a "reformed" (at a late age) pick-up artist, but I recommend the book.
