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

3D Shapes

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)
    -basket (rectangular prism)

    Sincerely,
    Jennifer E

  3. Kong

    Dear 5 White and Miss Azzopardi,

    Some objects that are 3D shapes are….
    -TV (Rectangular Prism)
    -Tissue Box (Square Prism)
    -Bookshelf (cube)

    And much more!

    Kind Regards,
    Kong

      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

    • Jennifer E

      Dear Cecilia,

      You found a lot of shapes. Great job

      Kind regards,
      Jennifer E

    • Dear Cecilia,
      WOW!!!! You have learnt a lot during the topic of 3D Shapes!

      Kind regards,
      Natalie

    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
