Lesson seeds are ideas that can be used to build a lesson aligned to the CCSS. Lesson seeds are not meant to be all-inclusive, nor are they substitutes for instruction. When developing lessons from these seeds, teachers must consider the needs of all learners. It is also important to build checkpoints into the lessons where appropriate formative assessment will inform a teachers instructional pacing and delivery.
According to the Partnership for the Assessment of Readiness for College and Careers (PARCC), some clusters require greater emphasis than others.
The table below shows PARCC’s relative emphasis for each cluster. Prioritization does not imply neglect or exclusion of material. Clear priorities
are intended to ensure that the relative importance of content is properly attended to. Note that the prioritization is in terms of cluster
