What are some of the top K12 curriculum providers?

Community Explorer

We run a K12 school that is both blended and completely online. I am hoping to source 5-10 curriculum providers that we can look into. We are looking for core subjects; math, science, social studies, and English language arts. The curriculum will need to align (even loosely) with Oregon standards and CCSS. We have used FlexPoint for years, and are hoping to Frankenstein more curriculum. FlexPoint curriculum works well for 7-12 mostly, but our K-6 are hoping for something to better meet their student needs. Any names or ideas is greatly appreciated!
