A couple of my favorites were developed by the regional science coordinators who work for the Washington State ESDs. These tools are:
– The NGSS “cheat sheet” a 2-sided color key to the 3 dimensions of the NGSS and the abbreviations.
– The NGSS placemat– an 11x 17 colorful sheet for deconstructing a performance expectation of the NGSS during a PD session.
I have used both of these tools with multiple K-12 teachers during initial professional development on the structure of the NGSS
