Hello my wonderful Grade 5 superstar! π
I'm Kashef and today we're learning about Cylinders! A cylinder is a 3D shape with two flat circular ends and a curved side that connects them. It looks like a can or a tube! Ready to roll and explore? Letβs go! π
π§ What is a Cylinder?
A cylinder has:
- 2 circular faces (top and bottom)
- 1 curved surface
- 2 circular edges
- 0 vertices (no sharp corners)
A cylinder β perfect for rolling!
π Cylinder vs Rectangular Prism
Cylinder: Round ends, can roll
Rectangular Prism: Rectangle ends, has corners
π― Letβs Practice with Cylinders!
1. How many flat faces does a cylinder have?
2. Why can a cylinder roll but a cube cannot?
3. Name 3 things that are cylinders.
