🗣️ Number Talk Teacher Scripts

Monday Script - Solar Panel Arrays

Problem: "We have 6 rows of 8 solar panels. What do you notice? What's another way to solve?"

Teacher Script: "Good morning, mathematical thinkers! Look at this problem up here. I want you to think silently first - no hands up yet, no talking. Just think about what you notice and how you might solve this.

[Wait 30 seconds]

Now, turn to your math partner and share what you're thinking. I'm listening for different strategies.

[Students share for 1 minute]

Alright, let's hear some ideas. Remember our number talk norms - we listen to understand, we ask questions respectfully, and we build on each other's thinking.

Who wants to share what they noticed about 6 rows of 8 solar panels?"

Potential Student Responses & Teacher Follow-ups:

"I see 6 × 8 = 48" → "Tell us more about how you visualized that multiplication."
"I counted by 8s six times" → "Show us that skip counting. Can someone connect that to what [student] shared?"
"I did 6 × 10 = 60, then subtracted 6 × 2 = 12, so 48" → "Interesting! You used what's called the distributive property. Can you show us that thinking with the rekenrek?"

Closing: "Mathematicians, you showed us that 6 × 8 can be solved in multiple ways - direct multiplication, skip counting, and breaking apart numbers. Tomorrow we'll explore how these strategies help us with larger numbers."

Tuesday Script - Building Thinking Problem

Problem String: Rational number relationships

Teacher Script: "Today we're going to work through a series of connected problems. Each problem will help us understand the next one. Let's start:

Problem 1: 'A community garden uses 1/2 of its space for vegetables. If the garden is 24 square meters, how much space is used for vegetables?'

Think quietly... [pause] Share with your partner... [pause]

What did you figure out and how?"

[Continue with string, connecting each problem to the previous]

Diameter - A line segment that passes through the center of a circle and connects two points on the circle

Example: If the radius is 5 cm, the diameter is 10 cm

Origin - The point where the x-axis and y-axis intersect; (0, 0)

Example: The origin is located at coordinates (0, 0)

Parallel - Lines that never intersect and are always the same distance apart

Example: Railroad tracks are parallel lines

Perimeter - The distance around the outside of a two-dimensional shape

Example: The perimeter of a square with side length 4 is 16 units

Perpendicular - Lines that intersect at right angles (90°)

Example: The corner of a rectangle shows perpendicular lines

Quadrant - One of the four regions of a coordinate plane

Example: The point (3, 4) is located in Quadrant I

Radius - A line segment from the center of a circle to any point on the circle

Surface Area - The total area of all faces of a three-dimensional figure

Example: A cube with side length 3 has surface area 6 × 3² = 54 square units

Vertex - A corner point where two or more lines, edges, or sides meet

Example: A triangle has three vertices

Volume - The amount of space inside a three-dimensional figure

Example: The volume of a rectangular prism is length × width × height

Statistics & Data Analysis

Data - Information, especially numerical information

Example: The test scores 85, 92, 78, 95 are data

Distribution - The way data values are spread out

Example: The distribution of heights in a class might be mostly clustered around the average

Frequency - How often something occurs

Example: The frequency of rolling a 3 on a die is the number of times it appears

Interquartile Range (IQR) - The difference between the third quartile and first quartile

Example: If Q1 = 25 and Q3 = 75, then IQR = 75 - 25 = 50

Mean - The average of a set of numbers

Example: The mean of 4, 6, 8, 10 is (4+6+8+10)/4 = 7

Median - The middle value when data is arranged in order

Example: The median of 2, 5, 8, 12, 15 is 8

Mode - The value that appears most frequently in a data set
