Recommendation needed: 1st grade (native) English curriculum for independent study

My daughter is attending local public school, but her English level is way beyond what they are doing in her English class at school. I want to pull her and teach her myself during the time allotted for that class - her teacher agrees with this plan, but of course I need to have a study plan. And here’s the thing: while I’ve taught EFL for two decades now, I’ve never taught it as a primary language! Can anyone recommend a good curriculum?

Google can help you the most. Perhaps an e book from Amazon can help you understand her level and where she needs to focus her learning.
