Kindergarten Number and Operation Sense (K.NOS)

Exploring the Revisions

The revised standards are presented in a crosswalk format, displaying the new standards alongside their previous versions to clearly highlight shifts in content and instructional focus.

Open the Kindergarten MCCRS Mathematics Crosswalk. Explore the standards within the Number and Operation Sense (NOS) domain. As you review, use the following guiding questions to identify key changes:

- What standards have been added, removed, or revised?
- What shifts do you notice in terms of instructional focus or clarity of language?
- Are there new skills or concepts introduced that were not previously emphasized?

Make note of or highlight specific examples that stand out to you.

Use what you've learned from your review of the K.NOS standards within the Crosswalk to answer the question. You must answer the Quick Check question to continue to the next part of the course.

place value models: While place value models are a valuable resource, they are not the instructional focus of K.NOS.C.10.
number paths: Correct: The use of number paths is foundational to students' work with number lines in later grades.
