NSTA has been slowly adding NGSS resources to their NGSS@ NSTA hub. This week they released a more clearly organized “gateway” to these resources. Click HERE to search and browse for NGSS resources. Resources are vetted and curated by the NGSS@NSTA Curators. Each resource starts with an introduction page that describes the resource and how it connects to NGSS. This page also contains connections to specific performance expectations and may say something like… “This resource is explicitly designed to build towards this performance expectation.” Many resources are FREE but I did notice that a few require a fee or a registration.

Thanks for the helpful links! I start my student teaching in the fall and I can use all the resources I can get!
