Early Numeracy Interview-Revised is an assessment for students in grades K-4. The interview is the second book in the series, Elementary Math Intervention. The interview may be used by math curriculum coordinators, math coaches, elementary classroom teachers and special education teachers. It is a revision to the Early Numeracy Interview from Australia, which was part of the Early Numeracy Research Project. This revised interview is much shorter, which allows for it to be used in the context of Response to Intervention.
