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.

In this lesson, students begin to move beyond counting as a strategy for solving addition and subtraction problems. They will use what they know about numbers and relationships between numbers to add and subtract with other strategies. Students will start to see connections between strategies to help them transition their thinking.
