Cones!

Pointy 3D Shapes with a Round Base

Grade 5 Ontario Math πŸ“š β€’ Geometry & Spatial Sense

Hello my wonderful Grade 5 superstar! πŸ‘‹

I'm Kashef and today we're learning about Cones! A cone is a 3D shape with a flat circular base and a curved surface that comes to a point at the top (the apex). It looks like an ice cream cone or a party hat! Ready to explore pointy shapes? Let’s go! πŸš€

🧠 What is a Cone?

A cone has:

  • 1 circular base
  • 1 curved surface
  • 1 vertex (the pointy top)
  • 1 circular edge

A cone β€” wide at the bottom, pointy at the top!

πŸ”„ Cone vs Pyramid vs Cylinder

Cone β†’ Round base + curved sides

Pyramid β†’ Polygon base + flat triangular sides

Cylinder β†’ Two round bases + curved sides

🎯 Let’s Practice with Cones!

1. How many flat faces does a cone have?

1 circular flat face (the base)

2. What is the pointy part of a cone called?

The apex or vertex

3. Name 3 things shaped like cones.

Ice cream cone, party hat, traffic cone, funnel, pine tree
