We’ve used several lol. We started out using a couple of all in one box set curriculums, since we had no idea what we were doing and those come with everything you need. This year we used an online curriculum called Time4Learning. There were some things I liked about each of them but I didn’t love any of them completely. I’ll probably piece his curriculum together for this next year now that we have a little better idea what we’re doing and what our state requires.
