These documents were created to help teachers who struggle with how to create a science course with a cohesive flow of the standards in mind. Each grade level or course contains a sample way to bundle the standards (there isn't just ONE correct way!) and a summary of how these unit bundles can flow together with the crosscutting concepts of NGSS in mind . These are a work in progress!!!
Elementary - K-5 Sample Bundles and Summaries
Middle School - 6-8 Sample Bundles and Summaries
High School - HS course sequences and bundle samples
Next Generation Science Standards - Kentucky Academic Standards for Science
NGSS appendices - progressions of the three dimensions (DCIs, SEPs, CCCs)
Task Prescreener and Screener - to evaluate CEAs
Performance Expectations Bundling - guides, examples, steps to follow
Tools 29, 30, 41 - useful for writing three-dimensional assessment tasks
