This is a resource for Common Core planning that I have found useful in planning for differientiated instruction. Each section has it's own tab (Numbers and Counting, Operations and Algebra, Fractions, Base Ten, Measurement and Data, Geometry) where you can see what the standard states are for each grade level, K-5 side by side. For example, if you work with a 2nd grade student that is performing one grade level below in measurement, you can click on the measurement and data tab and see the standards for first grade and kindergarten so you can align your instruction with the grade level standard your student is currently working at. On the other hand, if your student has mastered the grade level standard, you can use this resource to easily find the standard for a grade level or two above to accelerate the student's learning. With this packet, you have all of the Math standards K-5 in one place for easy reference. I have left this document as an Excel file so you can cut and paste as needed for your grade level needs.
