Practical Task 3/12/24

3D Shape Detective Task

Objective: Explore 3D shapes at home, sort them into groups, and count their faces, vertices, and edges.

Instructions:

1. Find 3D Shapes at Home
   Look around your house and collect items with different 3D shapes. For example:

   • A cereal box (cuboid)
   • A ball (sphere)
   • A can (cylinder)
   • A dice or cube toy (cube)
   • A party hat (cone)

   Tip: Try to find at least 4 different shapes!

2. Shape Sorting

   • Sort the items into groups based on their shape.
   • You can use this guide to help:
     • Cuboid: A box shape with flat faces.
     • Sphere: A round ball with no edges.
     • Cylinder: A shape with two flat circles and one curved surface.
     • Cone: A shape with one flat circle and one pointy end.
     • Cube: A box where all the faces are squares.

3. Counting Challenge
   For each item you found, count the:

   • Faces: Flat or curved surfaces.
   • Edges: Where two faces meet.
   • Vertices (corners): Where edges meet.

   Example Table:

   Item	Shape	Faces	Edges	Vertices
   Cereal Box	Cuboid	6	12	8
   Orange Ball	Sphere	1	0	0
   Baked beans can	Cylinder	3	2	0

4. Draw Your Shapes
   Draw one of the 3D shapes you found and label its faces, edges, and vertices.

5. Write a Short Report

   • What shapes did you find most often in your house?
   • Which shape was the hardest to find?
   • Did any items not fit any of the shapes?

Bonus Challenge:
If you have playdough, try to make your own 3D shapes and count their faces, edges, and vertices.

Have fun being a 3D Shape Detective!
