I can't believe I forgot these!
I've been using the Explode the Code books for six or seven years. They are really, really good!
I should have included them in the First Grade post.
You can find them here, among other places.
Just this year I ordered Jesus Calling by Sarah Young. I read it with my little girls each day as part of our Bible time. We love it!
You can order here.
That's all for now, unless I think of something else. :)
(Truth be told you could teach First Grade with just a Bible, a phonics book, and some pencils, paper, and crayons.)
