Over the past few months I have been using the Seattle Public School standards as well as the HighScope COR for toddlers and preschoolers to guide my teaching. As a former public school kindergarten and first grade teacher, I keep those standards in mind in preparing our children for kindergarten. Another resource I refer to are the early learning and development benchmarks for Washington state. I was so excited to find that HighScope has aligned some of their COR with the state benchmarks. This was something that I was going to try and do slowly over time. Here is a link to the Washington State to COR Alignment which is current as of January 2010.
