I have always found it difficult to understand the Common Core Math Standards. Sometimes I feel like I have no clue what the standard is asking for. Therefore, it makes it difficult to plan and assess. A book I have found super helpful this year is called, “The Common Core Mathematics Companion: Standards Decoded.” In this book it explains the standards, shows you example problems for each standard, tells what the teacher and student is suppose to do for this standard, and outlines common misconceptions to be aware of as you plan instruction. I have found it so much easier to plan and assess instruction now that I have a clear picture of the types of problems these standards are aiming towards.
