If you haven’t already, you might want to check out OSPI’s review of open educational resources for many subjects. You’ll find them  here https://www.oercommons.org/hubs/washington .  If you click on the resource itself the “View Resource” link will take you directly to the curriculum materials. The OSPI page for each resource gives a summary of that resource and also links to CCSS standards if there are any. The state is reviewing these resources as part of a legislative mandate that OSPI look into the free resources that are available for districts to use. The team will be looking into more grade levels and subjects in the future.
