This lesson should occur after the Partner Quick Flash lesson, which introduces conceptual subitizing. Candy Quick Flash continues to encourage conceptual subitizing an efficient way to find "how many".
Notes:
Perceptual subitizing: instantly recognizing "how many" in a set
Conceptual subitizing: efficiently finding "how many" by recognizing and combining subgroups within a set

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.
