Understanding Subitizing: Enhancing Number Sense in Today's Math Classroom

This presentation by Tomi Long introduces the concept of subitizing, the ability to quickly recognize and quantify groups of objects without counting individually. Through engaging visual examples and interactive questions, participants learn how their brains naturally process quantities. The session emphasizes the importance of recognizing patterns in math and how standardized configurations aid in understanding numbers. Discover why symbols mean nothing without foundational understanding and explore the math around us. Ideal for educators seeking innovative methods to enhance their students’ number sense.
