Measuring Early Mathematical Reasoning Skills: Developing Tests of Numeric Relational Reasoning and Spatial Reasoning

The primary aim of the MMaRS study is to develop a mathematics assessment system to use for grades K-2 that measure students’ abilities in two foundational and predictive constructs, numeric relational reasoning (NRR) and spatial reasoning (SR). Teachers may use results of these assessments to guide their instructional decision making to support student learning of these constructs. The objectives of the project are to develop formative assessments supporting each grade level (K-2) for each of the NRR and SR constructs and collect validity and reliability evidence.
