Oregon Content Standards has links to all of the content standards and benchmarks for the state of Oregon. They are searchable by area and grade level on the O.P.E.N. site. ExploraSource allows you to select a subject and grade level. Then select a specific topic and choose the state to match for standards. A list of software, audio, video, print, and web resources are generated by the search.
Some materials are free, some are low-cost, and some are commercial products.
Comparing the standards can be useful in evaluating lesson plans or texts that are already tied to a different state's standards to see how those standards compare to the Oregon statndards.
