Math Reasoning Inventory
This is a free Web-based math assessment tool designed to help teachers evaluate "students' numerical reasoning and understanding of math principles," according to information released by the company. Focused on skills required by the Common Core State Standards, MRI is designed to assess incoming middle school students' skills and conceptual understanding of whole numbers, fractions, and decimals.
Central to MRI is a 10-minute interview between a student and a teacher who is logged into the tool. Throughout the interview, the student is asked to solve problems in their heads with a few exceptions, and to explain how they got to them, whether they were right or wrong. Once completed, the results can be used to generate reports on what reasoning skills each student was able to demonstrate.
