Measurement is the process of accurately determining the extent, amount, or quantitative value of an attribute such as length, weight, volume, or area. In this handout, we first consider the basic concepts that form the foundation of measurement, then we examine exact measurement, and finally we discuss estimation.

The following handout presents an accessible overview of the mathematics of measurement. It provides important information on the foundations of measurement and ideas for supporting development of measurement skills in the preschool classroom.

Measurement in early childhood involves important mathematical concepts that can be supported in the preschool classroom through children’s everyday problem solving. This handout provides insights into children’s development in this important domain and gives examples of classroom applications.

We often think of graphs and charts when we think of data. But children collect data all the time without them. This handout describes the ways in which humans use data throughout their lives.

This page consists of video clips that are designed to illustrate assessing students using the measurement assessment protocol.

These tasks are designed to help you use the clinical interview to assess an individual child’s understanding of measurement.  

Supporting children to notice and describe what they notice is a productive way for teachers to leverage the ways in which children naturally find pattern in the world around them. This resource provides an overview of how teacher educators can engage teachers in this idea.

Additional videos related to how teachers support children's learning of patterns and algebra.

These tasks are designed to help you assess an individual child’s understanding of patterns. The protocol begins with relatively simple concepts such as recognizing and completing repeating patterns and moved on to more advanced concepts like growing patterns.
