Spatial Relations

Early learning of geometric ideas, and how things are related in space.

Why and What of Spatial Relations

Why learning to reason about space and spatial relations is crucial for children’s early mathematics learning. 

Mathematics of Spatial Relations

Several different approaches to explicating the important mathematics that underlies the content area of spatial relations.

Development of Children's Spatial Relations

How children think about shape and space. The explanation relies on analyses of videos portraying key aspects of children’s developing understanding of shape and space. 

Assessing Spatial Relations

Materials designed to explain and illustrate the importance of formative assessment of children’s understanding of shape and space.

Supporting Classroom Practice

Resources that teacher educators can use to support teachers to develop classroom practice that engages young children in spatial relations.


Fictionalized but very real examples of student experiences in learning to teach and in teaching early math.

Getting Started

Teacher educators are invited to use these materials flexibly, with varied settings, amounts of time, and participants. We present a variety of possible ways of getting started with these resources.
