1st grade common core/curriculum

I am homeschooling my son, and I am researching to find the standard common core/or curriculum for 1st graders for all subject areas such as mathematics, science, writing, reading, spelling, language arts, history, and arts.  I would like to know if any of you would recommend me or suggest me books I may purchase to base the lessons. Or even websites would be quite helpful.

I look forward to hearing from you.

Thanks

Fabiana
