### Number Talks Book Study: Part 3

Welcome to week 3 of our book study on Number Talks.  This is a great book for K-5 classroom teachers, special educators and math specialists.  It is also a great book for administrators and other educational professionals to read to learn more about what good math teaching looks like.

Thank you to all who participated last week!  We certainly had fewer comments than the first week but I am sure this is because folks got busy!   If you missed last week, no worries, just catch up as you have time!

#### Chapter 4 How Do I Design Purposeful Number Talks in the K-2 Classroom?

I particularly want to talk more about the dot images section in the K number talks.  I love using dot images with kids and can't believe I ever taught primary without these.  They are such a great way to build fluency with numbers and really lay the foundation for working with composing and decomposing numbers which is vitally important to students being successful with developing fluency of addition and subtraction facts.  As an interventionist, I often find that first and second graders whose teachers have identified them as needing more work with addition and subtraction facts are the kids who need more work with dot images and other models like 10 frames and rekenreks.  When I pull intervention groups from the classroom or work in classes during Guided Math time, I often will do a number talk with a small group.  By sometimes doing small group number talks, I can differentiate instruction and get to really watch how kids are solving problems.

I love all the models discussed and used in number talks.  Rekenreks are powerful tools and if you don't use these in your classroom yet, than you should!  There are free virtual versions and they are easy to build student size versions using pipe cleaners, cardboard and pony beads.  Ten frames are also fantastic and there are so many ways to use them in the classroom.  In addition to ten frames, I use a double ten frame (aka 20 frame) to extend the power of this model to larger numbers.  These models are important to have in every K-2 classroom and you will find yourself using them again and again during number talks, math centers and for individual student practice.
