Screen all students to identify those at risk for potential mathematics difficulties and provide interventions to students identified as at risk.

"The single-component approaches with the best ability to predict students’ subsequent mathematics performance include screening measures of students’ knowledge of magnitude comparison and/or strategic counting." (https://ies.ed.gov/ncee/wwc/Docs/PracticeGuide/rti_math_pg_042109.pdf)

Possible screeners to consider:

• • FAST EarlyMath

  • Number Sense Screener (Jordan & Dyson)

  • Acadiance

  • Number Fly

If the Kindergarten or Grade 1 student is flagged by the screener, begin a researched-based set of lessons teaching number and operations using a developmental progression (Recommendation 1, IES Guide), such as Number Sense Intervention.

Contact your Great Prairie AEA Math Consultant to learn how you can purchase manipulative sets for use with your small group.

Progress monitoring measures in the primary grades typically reflect aspects of number sense, including strategic counting, numeral identification, and magnitude comparison.

Use a valid and reliable progress monitoring measure. This training is recommended: Best Practices in Math Progress Monitoring.
