PreK Reasoning with Data, Statistics, and Probability (PK.DS)

Exploring the Revisions

Open the PreK MCCRS Mathematics Crosswalk. Explore the standards within the Reasoning with Data, Statistics, and Probability (PK.DS) 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 PK.DS standards within the Crosswalk to answer the question. You must answer the Quick Check question to continue to the next part of the course.
