4. Number Talks • First time hearing about them • Aware of them • Have tried them • Tried them and stopped • Do them regularly

5. What Are Number Talks? Instructional Routine • 3-4 times a week for about 10 – 15 min – consistency is important • Opportunity for students to mentally reason with numbers • Students share their solutions and strategies and their solutions are recorded and honored • Allows students to consider different perspectives on how a problem can be solved • Opportunity for students to reflect on and compare their solutions with other students’ solutions.

6. Why Number Talks:a high-leverage teaching strategy/routineto transform the culture of the classroom

7. The “Routine” • Students put paper and pencil away • Teacher writes a problem on the board – left to right, not one below the other • Students put a thumb up once they have an answer – additional fingers if they have more than one way of solving the problem • Once most thumbs are up, teacher records the answers only on the board – asking if anyone has a different answer. No reference is given as to whether the answer shared is correct or incorrect. • Teacher asks for volunteers to explain how they figured the problem out, student clarifies which answer they are defending, and teacher records the strategy and might ask the class “does anyone have a question for ____________”, “can you say more about____________?” • Teacher records the student’s solution as the student explains it.

10. Tips for Getting Started I was originally inspired and get re-inspired to use Number Talks from: • Jo Boaler models how to do Number Talks video from Youcubed • Ruth Parker and Cathy Humphrey talk about their book Making Number Talks Matter • Attend or Sponsor an event by the Mathematics Education Collaborative.

11. How Students Change Over Time • More students talk about their math ideas during other parts of class • Many students become more confident about their math ideas • Students hear others’ ideas and acknowledge the other’s ideas in later conversations • Some students become quite animated about trying to think of new ways to work with numbers and visual patterns • Some students become willing to go beyond the written algorithms and to notice arithmetic properties • Math vocabulary gets spoken aloud while students explain their strategy

12. NUMBER TALK EXAMPLES Multiplication problems: • I write answers offered by students • I invite students to defend their answers • I write students’ names with their strategy • I encourage students to name strategies (as in Double and half) • Iask students to make a note of a new or impressive strategy shared today http://kes-5thgrade.blogspot.com/

13. NUMBER TALKS WITH VISUALS Ioccasionally model students’ approaches with area models of multiplication This visual representation supports teaching polynomial multiplication methods and the distributive property Below is an example for 18 x5 from Jo Boaler’s work on Youcubed

14. NUMBER TALKS with GROWING PATTERNS I regularly explore growth patterns using a modified number talk format and Fawn Nguyen’s Pattern Lesson idea. Students try to answer these questions.. • How do you see this pattern growing? • Sketch the first 4 steps of the pattern and the 13th form of the pattern. • Without sketching all of them out, how many snowflakes will be in the 43rd step? patterns from - http://www.visualpatterns.org/

15. How Number Talks on Growing Patterns Started I build students’ capacity to have this type of number talk with a whole class lesson. (Fawn Nguyen) Student pairs figure out different patterns and create posters. Each week we have at least one brief Growing Patterns Number Talk.

16. Successes and Challenges Successes with implementing Number Talks • Getting the talks down to about 10 minutes by using a timer • Finding places in the curriculum to insert number and math talks • Both the Math Coach and Principal commenting on the math conversations observed among my students while they worked Challenges for implementing Number Talks • Ensuring ways to keep them in my weekly class routines • Figuring out worthwhile, small problems to discuss • Having educator allies to share the load for planning Number Talk topics for Algebra classes

19. Tips for Getting Started with Number Talks • Just made the plunge after talking with our Interventionist and seeing the book at a training. • Hoped it would make students less intimidated by mental math (put those calculators away!) It did. • I started with single digit numbers multiplied by double digits, and worked into a problem like 18x19=

20. Immediate Change • I saw immediate improvement on participation levels. • Endurance for the rest of the lesson also improved dramatically.

21. Change over Time • Unexpected result – It was great scaffolding for what we were trying to accomplish in Alg II, namely factoring polynomials. • Multiplication to area models • Area models to factoring quadratics • Led to another model for dividing higher order polynomials • Led to connections for synthetic division

25. Supporting Number Talks • Implementing NT’s was decided by math PLC after discussion around SMP3 (construct viable arguments and critique the reasoning of others). • I facilitated a book study on Making Number Talks Matter • Used PD day to develop common talks and commitment to routine • I provide support by co-planning, co-teaching, modeling and observing with Guiding Principles feedback

26. Impact? • More engaged students and a larger emphasis on thinking • Using mental math strategies in other aspects of lesson, “we don’t need a calculator for that, its like a math talk” • Spotlights power of differentiation • ELA team looking for something similar

27. Successes and Challenges • Successes: All math teachers implementing math talks and have interest in pushing practice forward. • Teachers use of “talk moves” to help orient students to each other and to academic discussion. • Special Ed teachers interested in using them to help their students. • Challenges: Put more emphasis on student thinking and carry over this principles of number talks into the rest of the lesson

29. We Are Learners Along With the Students- • Ask purposeful questions that shift the focus from the teacher to the student. • Bring student solutions back to a PLC –particularly if you are unsure about a student’s strategy. • Build your own content knowledge by making sense of the many new strategies your students will come up with!
