Number Talk – CoxSc # Video Audio1 VIDEO Opening TBD Music up about 3-5 seconds before narration …

VOC: Good Morning. My name is Claude Cox and I am a Math Teacher Development Specialist with the Elementary Curriculum and Development Office.

2 Objective VOC/VO: In this video I will be modeling one of the daily math routines: number talk. This routine is typically done at the beginning of the math block and should only take about 5 to 8 minutes to complete. It is important to remember that students should use mental math strategies to solve. They will not need any writing utensils. This specific number talk will take place on the rug (gathering place). Refer to the anchor charts video for an example of how to transition students from whole group to a gathering place.

During this video, you will see me prompt third grade scholars to solve the number sentence: 13+22 mentally.

3 STEP 1: Planning for a Number Talk

(Work through possible responses for number talk showing ideas on camera)

VOC: Planning plays an essential role in the implementation of number talks. Since number talks asks for students to problem solve mentally, you will need to strategically preselect the number sentence you wish for them to solve. Teachers may select a particular skill they are covering in class, practice a skill previously taught, or address a common misconception. VO: After choosing the number, it is vital that we think about potential exemplar responses. For example, with the number sentence 22+13, a student may say that they noticed 22 has 2 tens that equal 20. 13 has one 10 and 10+20=30. 22 has 2 ones 13 has 3 ones and 3+2=5. 30+5=35. Exploring possible student responses is important and will help better prepare you for having an effective number talk.

4 STEP 2: Preparing the location

VO: Like number of the day, your next step is to determine a gathering place or location where you will have your number talk. Many teachers may choose an area of the room separate from where their students normally work. Other teachers may choose to have students stay at their desks. Once determined, it is important to keep this procedure/process as consistent as possible. You will need chart paper, marker, and a response signal to ensure that students understand the how they will respond.

5 STEP 3: Number of the Day (with students)

Prepare an anchor chart with the number sentence or problem you selected.

Supplies needed: Chart paper and markers

VOC: Good morning, boys and girls! Today we will be having a number talk. It’s just like a conversation but we will be talking about a math problem. We will not all speak at the same time. When your classmate is talking we need to pay close attention to what he or she is saying without interrupting him or her. I want everyone to participate by trying your best to solve this problem using your brain (teacher will point to brain, students point to brain. You guys ready? I am about to write a number sentence on the chart paper. I want you to try and solve it as many different ways as possible. When you have solved the number sentence, I do not want you to say your answer, but I want you to hold your fist to your chest. Let’s practice. (Students will hold fist to chest). If you find an answer quicker than your classmates, I want you to think of another way. You can hold a 1 on your

chest if you find another way, 2 if you have found 2 ways and so forth. Here is the problem I want you guys to solve: “22+13=.” Take a moment to think of as many different ways you can solve this problem. Go!

(Call on student) Can you tell me how you solved this problem mentally? (Student will explain their thinking)

Repeat 2-3 times depending on how many students are present.

8 Close VOC: What you just witnessed was an example of a number talk using a preselected number sentence in a second grade classroom. This can be very intimidating for students at first, so it is suggested that you create a healthy and welcoming classroom environment that students to be open about their thinking. Also, ensure that your content is grade level appropriate and remember to be strategic about the problem you choose.
