Teaching 3D shapes

2. WHICH ONE IS BIGGER? MATCH THE
DENOMINATORS!
1) ½ OR 6/8
2) 1/3 OR 7/9
3) 10/12 or 4/24?
4) 2/5 OR 9/15
5) 4/5 or 13/20

3. LO – TO UNDERSTAND THE PROPERTIES OF 3D
SHAPES
LETS RECAP FROM YESTERDAY.

4. HOW CAN WE DESCRIBE THESE
SHAPES?

5. WE CAN USE WORDS LIKE…
FACES
EDGES
VERTICES

6. FACES OR SIDES
All 3D shapes have faces.

7. EDGES
All 3D shapes have edges apart from a sphere.

8. CORNERS OR VERTICES
All 3D shapes have vertices apart from
a sphere.

9. WE CAN ALSO SAY WHAT SHAPE
THE FACE IS.
The face is the
shape of a
square.

10. USING THESE WORDS, HOW
COULD WE DESCRIBE A CUBE?
It has…
•6 faces that are
square shaped
•12 edges
•8 vertices

11. I AM A PRISM

12. I AM A PRISM

13. PRISMS

14. I AM A PYRAMID
I have one base (also called a face).
All my other faces slope and meet at one point.
I am a Non-Prism

15. Non-Prisms
PYRAMIDS
