Does anyone have any great resources listing everything a child needs to know pre-k-12?

I want to do my own lesson planning and use products from multiple companies. So I just need a resource that tells me a list of everything a kindergartner needs to learn and everything a 1st grader needs to learn and so on up to 12th grade so that I can make plans for what sort of activities and books to buy on ebay or just rent at the library
