Math Standards

  • The following eight standards for mathematical practice apply to students at all levels (K-12) as they seek to develop their mathematical expertise: 


    1. Make sense of problems and persevere in solving them.
    2. Reason abstractly and quantitatively.
    3. Construct viable arguments and critique the reasoning of others.
    4. Model with mathematics.
    5. Use appropriate tools strategically.
    6. Attend to precision.
    7. Look for and make use of structure.
    8. Look for and express regularity in repeated reasoning.



    Illinois Learning Standards/Common Core State Standards (CCSS) 

    Illinois, along with over 40 other states, have adopted the Common Core State Standards (CCSS) in mathematics to improve student college and career readiness. The standards provide clear, consistent and rigorous expectations for students by grade level. The New Illinois Learning Standards focus on fewer topics at each grade level, allowing students to develop deeper conceptual understanding and math fact fluency.  


    The Illinois Learning Standards for math are based on the CCSS and define what students should understand and be able to do in their study of mathematics. Clicking on the hyperlinks below will take you to the Illinois Learning Standards for each grade level. While there are many mathematical standards, instructional time focuses on the following critical areas by grade:
