Session 1 Script

Mission Briefing (2 minutes)

Teacher (holding up a cube, a sphere, and a cylinder):
“Good morning, detectives! Today we have an exciting new mission. We’re going to explore 3-D shapes and become experts at finding their corners and edges. (Hold up the cube.) Let’s start with this shape. What do you think it’s called?”

Wait for responses.

Teacher:
“Great guesses! This is called a cube because all its faces are squares. Now, detectives, what do you notice about the corners of this cube? How many corners, or ‘vertices,’ can you see? Count them with me.”

Count aloud with students: “1, 2, 3…”
Teacher:
“That’s right—eight vertices! Vertices are where two or more edges meet. Now, let’s count the edges. Remember, edges are the straight lines where two faces meet.”

Count aloud: “1, 2, 3…”
Teacher:
“Good work—there are twelve edges on a cube. Let’s try the sphere next. (Hold up the sphere.) What do you notice about its corners or edges?”

Students notice there are none.

Teacher:
“Exactly! A sphere has no vertices and no edges. It’s perfectly round all over. Finally, here’s a cylinder. (Hold up the cylinder.) How many edges and vertices does a cylinder have?”

Guide responses toward: 2 edges, 0 vertices.

Teacher:
“Correct—two edges around the top and bottom, and no corners. Great detective work so far!”

Shape Sorting Detective Activity (4 minutes)

Teacher:
“Now I’m passing out the 3-D Shape Sorting Activity Cards. I want you to work with your partner to sort the cards into piles for cubes, spheres, and cylinders. Then quietly count and whisper to each other how many vertices and edges each card has.”

Distribute cards from 3D Shape Sorting Activity Cards.

Teacher (circulating):
“Show me how you’re counting those corners. One at a time—1, 2, 3… Do you have eight for that cube? Excellent! How many edges? Count with your finger along the line—1, 2, 3…”

If a pair is stuck:
Teacher:
“Remember, vertices are corners. Let’s count the points where two edges meet—point them out with your finger. Great, there’s one, two…”

Detective Worksheet Practice (5 minutes)

Teacher:
“Next up: your Vertex-and-Edge Detective Worksheet. (Hand out Vertex-and-Edge Detective Worksheet.) Look at the first shape on the worksheet. Write its name, then count and record the number of vertices and edges you see.”

Model the first item on the board:
“Here’s a drawing of a cube. It has eight vertices so I’ll write ‘8’ in the vertices column. It has twelve edges, so I’ll write ‘12’ in the edges column. Then you can do the rest.”

Circulate to support students:
Teacher:
“If you’re having trouble counting the edges, use your finger to trace one edge at a time. Show me your count—‘1, 2, 3….’ Perfect!”

Quick Quiz & Debrief (4 minutes)

Teacher:
“Time for our quick quiz! Please take one Session 1 Quick Quiz and work on your own to answer the questions. You have two minutes.”

Distribute and monitor.

Teacher (when time’s up):
“Please put your pencils down. Turn your quiz face-up on your desk. I’ll collect these and review your answers.”

Collect quizzes.

Teacher:
“Before we finish, who can share one thing they learned about vertices or edges today? Maybe you counted something interesting!”

Listen and affirm responses.

Teacher:
“Fantastic work, detectives! Next time, we’ll tackle more shapes and become even sharper at spotting corners and edges.”
