In this lesson, students will use perceptual subitizing* as an efficient method for determining "how many". Through experiences, students will subitize sets within five.

*Perceptual subitizing: instantly recognizing "how many" in a set
*Conceptual subitizing: efficiently finding "how many" by recognizing and combining subgroups within a set.

In this lesson, students will identify how many manipulatives are in a given arrangement without counting each individual object (focus on 1-5). Students will understand the relationship between numbers and quantities, and will explain this relationship as they determine "how many" are in a set.

Note: Perceptual subitizing means to instantly recognize "how many" in a set.

This resources is part of Tools4NCTeachers.A Number Talk is a brief routine (about 10 minutes) focused around developing flexibility and fluency with numbers. Through regular opportunities to work with dot images and expressions, students develop an understanding of number relationships and structure. This supports the development of early fluency skills.This PowerPoint contains presentation slides for daily Number Talks, as well as directions and videos for implementation. Teachers may facilitate the Number Talks on these slides, or use them to inspire their own Number Talks based on student need.
