Free 2nd Grade 3D Shape Construction Activity Sheets.

📚 Topic Summary

Three-dimensional (3D) shapes are all around us! Unlike flat shapes, 3D shapes have length, width, and height. Think of a cube like a dice, a sphere like a ball, or a pyramid like an Egyptian tomb. This worksheet will help you understand the different parts of these shapes, like faces, edges, and vertices (corners), and how to construct them using nets.

Using construction activity sheets makes learning about 3D shapes fun and interactive. By cutting, folding, and gluing, you'll get a hands-on experience that will help you remember what you've learned!

🧮 Part A: Vocabulary

Match the term with its correct definition:

1. Cube
2. Sphere
3. Vertex
4. Edge
5. Face

Definitions:

1. A flat surface on a 3D shape.
2. A solid shape with six square faces.
3. A round 3D shape like a ball.
4. A point where edges meet.
5. A line segment where two faces meet.

Write the number of the definition next to the corresponding term:

• 🎲 Cube: 2
• ⚽ Sphere: 3
• 📍 Vertex: 4
• 📏 Edge: 5
• 🟩 Face: 1

✍️ Part B: Fill in the Blanks

Complete the sentences using the words from the word bank:

Word Bank: edges, faces, vertices, pyramid, cone

1. A _________ has a circular base and a point at the top.
2. A _________ has a base and triangular _________ that meet at a point.
3. __________ are the corners of a 3D shape.
4. __________ are the lines where two faces meet.

Answers:

1. A cone has a circular base and a point at the top.
2. A pyramid has a base and triangular faces that meet at a point.
3. Vertices are the corners of a 3D shape.
4. Edges are the lines where two faces meet.

🤔 Part C: Critical Thinking

Imagine you are building a house out of 3D shapes. What shapes would you use and why?

(Example answer: I would use cubes for the walls because they are sturdy and have flat faces. I would use a triangular prism for the roof so the rain can slide off easily. I would use a cylinder for a chimney.)
