# 3D Space

Year five are currently learning about three-dimensional space. 3D shapes have length, breadth and height. Pyramids and prisms take their name from the shape of their base. Prisms have uniform cross-sections (cuts that are parallel to, and the same size and shape, as the base) whereas pyramids have cross-sections that are not uniform

Take a look at two students explaining the pairs of parallel faces on a 3D object below.

3D shapes are all around us in the built and natural environment! Take a look at the YouTube clip below.

What 3D shapes can you see at home and/or in the classroom?

Dear Five White and Miss Azzopardi,

I love learning about 3d space!! I learnt about interesting things like a plane, cross section, uniform cross section and more.

The things i see at home that are 3d space:
-container
-book
-bottle
-cupboard
-fruit
-television
-paper
-Lots more

Yours Truly,
Kevin

• Dear Kevin,

Wow, you have found a lot of 3D shapes around your house. I wonder if you or someone else could identify what 3D shapes each object is. I wonder if your television is a cube or a rectangular prism!

Kind regards,
Miss Azzopardi

Dear Kevin,

Thats a lot of 3d shapes you have there! I have a lot too but theres just too much aswell i can’t fit it otherwise it will take up a whole lot of space!

Sincerely,
Kong

2. Dear Miss Azzopardi and five white,

I love learning about 3D space!!!! The 3D shapes are……

-watch holder (square prism)
-bottle (cylinder)

Dear Kong,

You have learnt so much about 3D space and what type of shape it is.
Next time just add a question to your comment to make it better.

Sincerely Anthony

• Dear Kong,

Well done Kong! Although some televisions may not be a rectangular prism, some may be a cube, some more you could add are:

-Tin can (Cylinder)
-Ball (Sphere)
-Markers (Rectangular Prism)
-Book (Rectangular Prism)
-Clock (Rectangular Prism Or Cylinder)

Kind Regards,
Nathan

Dear Five White and Miss Azzopardi,

3D Space is a very fun topic in Maths! I learnt A LOT of new things about 3D Space!

The following 3D objects I see at home that are 3D are:

* Tissue boxes
* A Rubbish bin
* A Book
* A Bottle
* A Glue stick
* A Box
* A TV

Sincerely,
Cecilia 😀

• Dear Cecilia,

Well done! You have found many 3D shapes in your house. I wonder if you could identify what shapes each object is. I’m guessing the book is a rectangular prism. Am I correct?

Kind regards,
Miss Azzopardi

• Dear Miss Azzopardi,

You are correct!!! A book is a rectangular prism because it’s base is a rectangle.

• Tissue box = Rectanglular Prism
• Rubbish Bin = Cylinder
• Bottle = Cylinder
• Glue Stick = Cylinder
• A TV = Rectanglular Prism or a Cube

Yours Sincerely,
Cecilia

Dear Five White and Miss Azzopardi,

I have learnt a lot about 3D space. I have learnt how to draw the net shapes of 3D objects, what a plane is what vertices are and what uniform and not uniform- cross sections are. There are a lot of 3D objects around us for example: drink bottle, containers, a door and computer monitor. e.t.c
What 3D objects have you seen this week?

Sincerely Anthony
