Essential Questions: What makes a computational strategy both efficient and effective? How do mathematical ideas interconnect and build on one another to produce an answer? How can the four operations in decimals related to one another? How does one recognize the strategy to be used for a specific operation? How can models help us understand decimals? How can we determine the reasonableness of an answer when solving a problem? How are decimals different from whole numbers?

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 headings.
Key ◾ Major Cluster • Supporting Clusters ◦ Additional Clusters
Operations and Algebraic Thinking
Number and Operation - Fractions
Measurement and Data
