Video is a powerful tool for engaging participants in understanding children's mathematical thinking.  This example of using video in a preservice course illustrates how teacher educators can engage participants around carefully selected video clips. 

To teach well, you need to understand the individual child’s math knowledge. This document provides guidelines for conducting conversations that can reveal a child’s math thinking and guide your teaching. 

This article highlights the importance of both language and ideas for understanding and expressing spatial relations. Integrating spatial language and concepts poses distinctive challenges and opportunities for dual language learners (DLLs).

These tasks are designed to help you assess a child’s understanding of spatial topics. The protocol begins with relations like over, near, next to, and the like and progresses to a child’s understanding of symmetry.

These tasks are designed to help you assess children’s concepts of shape. The protocol begins with relatively simple concepts like attributes of two dimensional shapes and ends with the analysis of solid shapes.

Different approaches to learning what children know about shape and space. This article shows how participants can use observation, drawing, etc. to learn about children’s knowledge and language of geometric figures, physical and mental transformations, and spatial relations.
