Welcome to 1st Grade Common Core Math Standards Resource Page!
This page is your go-to guide for understanding and implementing the 1st Grade Common Core State Standards for Mathematics. Below, you’ll find a complete list of all the standards and skills, along with resources to help make your teaching more effective and efficient.
The Common Core Math Standards are organized into broad categories called Domains, with specific skills outlined under each. Within each Domain, Clusters group related standards that progress in complexity, ensuring a clear and cohesive structure for learning at each grade level.
For 1st grade, the key Domains include:
Each Cluster is further broken down into Standards, which are specific skills or concepts that students are expected to learn. For example, the standard 1.NBT.B.2 focuses on understanding place value, including recognizing that the numbers 10 through 90 represent groups of tens and some ones.
