Transcript 2-D or 3-D?— Let's Practise!
Razzi says get your thinking cap on because today we're going to practise choosing... "2D or 3D?" It's time to begin! Remember, 2D, or two dimensional, means the shape is flat and 3D, or three dimensional, means the shape is solid. 3D shapes look real whilst 2D shapes look more like drawings. Is this shape 2D or 3D? This shape is 2D because it is flat. Did you also say 2D? Let's answer the next question! Is this shape 2D or 3D? This shape is 3D because it is solid. Did you also say 3D? Here's another one! Is this shape 2D or 3D? This shape is also 3D because it is solid. Did you say 3D too? Let's try the next question! Is this shape 2D or 3D? This shape is 2D because it is flat. Did you say this shape is 2D as well? Let's try the last one! Is this shape 2D or 3D? This shape is also 2D because it is flat. Did you choose 2D as well? Razzi had so much fun practising with you today! See you next time!

-
Which are flat and which are solid?
HintsA flat shape does not have any faces. These are 2-D.
A 3-D shape has faces.
SolutionThe first group of shapes are all 2-D because they are flat.
The second group of shapes are 3-D because they are solid.
-
Are these shapes 2-D or 3-D?
HintsRemember, 3-D shapes are solid.
2-D shapes are flat.
SolutionThe sphere and the prism are 3-D because these shapes are solid.
The circle and the triangle are 2-D because the shapes are flat.
-
What type of shape is it?
Hints3-D shapes look solid and real.
2-D shapes look flat.
Solution- The cone is 3-D.
- The cuboid is 3-D.
- The rectangle is 2-D.
-
Are the shapes 2-D or 3-D?
Hints3-D shapes look solid. They have faces, edges and vertices.
2-D shapes look flat. They have sides.
SolutionThe square and circle are 2-D shapes.
The cylinder and pyramid are 3-D shapes.
-
Are they 2-D or 3-D?
Hints- 2-D shapes look flat or like drawings.
- 3-D shapes look real.
This is an example of a 3-D shape.
SolutionThe square and the triangle are 2-D shapes.
The cylinder and the cube are 3-D shapes.
-
How many of each shape type are there?
HintsHere is an example of a 3-D shape.
Here is an example of a 2-D shape.
SolutionThere are four 3-D shapes: cylinder, cube, sphere and cuboid.
There are three 2-D shapes: pentagon, kite and heart.
