Learning about Shape

We have recently been learning about shape in our maths lessons.

The world around us is made up of space and shape and these are very important concepts for students to understand.

We used Jenny Eather’s Maths Dictionary for Kids a lot to learn and revise vocabulary such as:

  • 3D shape
  • 2D shape
  • regular polygon
  • prism
  • pyramid
  • vertices
  • edge
  • face

We have enjoyed making 3D shapes with nets, drawing and labelling 3D shapes, counting edges, faces and vertices and playing a range of games to learn about 2D shapes.

If you would like to try some more activities about shape, you can find a collection of games on the Woodlands site here.

Shapes are all around us! What 3D shapes can you see in this photograph?

Can you name any 3D shapes in the photograph?

Can you define any of our shape vocabulary?

Did you try any of the games on the Woodlands site?

  1. Dear 4KM and 4KJ,

    Wow what a fabulous post, I really enjoyed seeing all the effort that went into this post!

    In answer to your first question I can see some cones, a square pyramid, a pentaganol prism, a cube, lots of pryamids and much much more!

    I haven’t really got any time to go onto the woodlands site because I am trying to leave lots of comments on different blogs in reading groups.

    I hope to see lots more amazing posts soon!

    From your blogging buddie,

    • Dear Jess,

      You’re right the effort they put into it is amazing.Jess,your comment is amazing aswell.

      For the first question my answer was the exact answert as yours.

      I have not had a chance to go on the woodlands site yet but I am going to after this comment. It is grteat to hear you are trying to leave lots of comments.

      From your blogging buddy,

    • Dear Jess

      What an awsome comment!

      I love learning about shapes,
      it’s such a fun topic.

      I also haven’t been on the woodlands shapes but I will.

      I have a question to ask you,

      Do you have a favourite shape and what is it?

      Got to go,
      L♥ren 😆 😯

    • Dear Jess,
      Thank you for commenting on the class blog. You are a good blogger. And so is everybody eles. It is good that you saw that there was a new post on the blog and you descided to leave a cooment on the post.

      Wow what a great post. Mrs Morris and Miss Jordan always put a lot of effort on to the post they are making. And they always do a wonderful job. But it is not surrising because they always do succseed.

      Like I said they always do an amazing job on the posts for the blog. They never fail and that is why they are such good bloggers. And they also tought us how to leave a qulity comment on the blog.

      That is good that you are answer the questions that are left on the blog. And that is why they are there because Mrs Morris and Miss Jordan want to see your answers to the questions. I can see lots of shapes in that picture and I will nme some of them.

      and lots more

      It doesn’t matter that you aren’t looking at the shapes woodlands because at lest you are replying or commenting on other people,teachers or students blog. And maybe they will reply to you and comment on your blog. Mrs Morris told 4KM and I don’t know if she told your grade that if you comment on their blog they will comment on your blog.

      From Maddy 😯 😈

    • Dear Jess,

      What a wonderful comment from a wonderful blogger! You are right, this post had a lot of effort put into it, and is just as quality as all the others.

      You are correct! All those shapes are in the picture. There are many more. I can also see a hexagonal prism and a triangular prism.

      I looked at a few of the Woodlands sites. I looked a lot a 3D Shape sites. I like learning about 3D shapes more than 2D shapes. I just do, I’m not sure why.

      Your friend,
      Liv 😆

  2. Dear 4KM and 4KJ,

    here i will list as many shapes in
    the picture i can.

    2.triangular prism
    4.square based pyramid
    The rest I have forgot the names.

    bye for now,

    Joshua 😀

    • Dear Josh,
      Theese are the shapes I can see.
      1. Cube
      2. Cone
      4. Pentagon
      5. Triangular prism
      6. Square based pyramid
      7. Egg
      I’m not shore if the egg one is right because I don’t know what it is called in 3D.

      Do you know what it is called?

      From your friend,

  3. Dear 4KM and 4KJ,
    the post was a great idea Mrs Morris!

    Well, the 3D shapes the I saw in the photo were cones, cubes, rectangular Prism (I think it’s that) and a couple more that I accidently forgot 😳

    Yes, I can difine some shape vocabulary.

    ■3D shape: A three dimensonial shape.

    ■2D shape: A shape that only has length and width (I need a little more work with remembering what they mean)

    ■vertices: Called a vertex when only one, sort of like the points

    ■edge: An edge is like the line that keeps the shape together.

    ■face: A face is like the shape on the outside.

    That’s really all I remember, I had another VERY late night, I slept through dinner I was so tired, and it wasn’t fron school.

    Your blogging buddy,
    Bronte :mrgreen: 😛 😯

    • Dear Bronte,

      Like always, thankyou for the long quality comment! You put in so much effort! You truly are an amazing blogger.

      I agree, this post is a gerat idea!

      I saw those shapes too! I also saw a pentagonal prism and a square prism.

      Your definitions of the shape vocabulary were perfect!

      They were exactly what I would have said if I had done it.

      When our learning focus was shapes, I learnt lots, like what a vertex was called when it has more than one, vertices.

      I also learnt what a prism was, a 3D shape with 2 regular polygons as bases, and all the other faces are rectangular.

      I learnt what a pyramid was. A 3D shape with a polygon as a base, with triangular faces that form a point at the top of the shape.

      Your friend,
      Liv 😆

  4. Dear 4KM and 4KJ,

    What a great post,I have enjoyed learning about 2D and 3D shapes in 4KM and 4KJ.

    Here are some of the shapes I can see.
    I can see a triangular prism,a cube,a cone and a pyramid.

    From your blogging buddy,

    • Dear Adam,
      you must have great eye sight.
      I can see a cone,cube and a pyramid and a triangular prism.

      from your blogging buddy Lachstar.

  5. Dear 4KM and 4KJ,

    I love the post about shapes! I haven’t tried any of the games yet because I just got on the blog! I will try some games at home and leave another comment to tell you about it!

    I can name some shapes in the photo, here they are:
    1. Cube
    2. Square Pyamid
    3. Pentagonal Prism
    4. Cone
    5. Triangula Prism

    Now, for the vocabulary.
    2D Shape: a shape that has length and width.
    3D Shape: a shape that has length, width and hight.
    Face: a flat side of a shape

    As I said before I haven’t played any of the games yet. But I better go, otherwise I’m going to miss snack!

    Iesha 😀 :mrgreen:

  6. Dear 4KM and 4KJ,

    I have thurrely enjoyed learning about space and shape. My favourite shape is the Trapezium, what is yours?

    I think I can name all the shapes in the picture:
    Pentagonal Prism.
    Pentagonal Pyrimad.
    Triangular Prism.

    Do you think I’m right?
    Can you name any more?

    Can any of you name 5 3D shapes that are in the area you are in. I think Shapes are very fasanating.

    I think everyone should know about shapes, Because the world is made out of shapes.

    Can you name the shapes on this website…


    Keep Useing Shapes.

    From Trent.

    • Dear Trent,

      My favourite shape would be a cone, I like the pointy top.

      Yes, I do think you are right. I can see that the most common shapes are in a pyramid and a prism.

      I can name…

      3D rectangle (tub)

      Cube (canteen basket)

      2D rectangle (whiteboard)

      Cube (dice)

      Cylinder (fire extinguisher)

      The shapes from the website from order are…



      Triangular prism

      Triangle (birds eye view)

      Square pyramid




      Am I right?

      Your Blogging Buddy,


      :mrgreen: 😀

  7. Dear 4KM and 4Kj,

    What a lovely post about shapes.

    I have really enjoyed about learning about them.

    My favourite activity would measuring the shapes and and adding them all up witch we did yesturday!

    I can see a few shapes in there some I THINK I can see are hexagonal prysm, cube, triangular prysm, cone,and I think a pentagonal prysm.

    I have not have enough time ti look at them right this instent but I have tried them before !

    Well nearly snack time better go,

    :mrgreen: 🙂 😉

    • Dear Clancy,

      Wow what an excellent comment, you are a really great blogger!

      I really enjoyed learning about the shapes. I also liked the mearuring too.

      My partner for the mearuring was Indi it was so much fun! Who was your partner?

      I saw all the shapes that you saw and maybe some more, I don’t really know.

      From your blogging buddie,

  8. Dear 4Km and 4KJ,

    This is a great post about shapes.
    I have learned a lot about shapes, I also didn’t know that another name for corner was a vertex.

    I have seen a lot of shapes around the world like a water tank is shaped as a cylinder or a window is a square.

    I can name some of the shapes in the picture,
    pentaganal prisim, cone, square pyrimin, triangular pyrimid, cube and a triangular prisim.

    from Tom

    • Dear Tom.

      I agree that that the post is great.
      I love learning about it.
      I am glad that you learnt what that was.
      I also have seen many shapes in our world. I also think those shapes are in the picture.

      From your friend Trent

      • Dear Trent,

        Thanks for the comment back to me
        there are a lot of shapes in the world.

        Can you name any of the shapes you know?

        What’s a shape you can make out of a octagan prisim?

        From your blogging buddy,

  9. Dear 4km and 4kj
    Wow what a fantastic post
    I think I can name a few of of the shapes in the back of the picture:
    triangulaur prism
    cubic prism
    octagonal prism
    and hexagonal prism
    some who reads this
    please correct me 😆

  10. Dear 4KM and 4KJ,

    I never relized that 3D shapes are all around us.
    My favourite shape is a sphere because it has 0 vetices, 0 edges and 1 side.

    In Grade 3 I learnt a little bit about shapes and all those things in learnt came straight back to me. (Thank-you Ms Wilson)

    I have learnt about all these different shapes that I didn’t even know existed and Mrs Morris and Miss Jordan gave me a great understanding of shapes. 🙂

    From Leah. ♥

  11. Dear 4KM and 4KJ,
    wow, what a great post, Mrs Morris.
    I think it’s a great idea to use Jenny Eathers Maths Dictionary because it’s a great way to learn your maths a very easy way not hard, you know what I mean?
    I hope you can answer my question.

    I love learning about shape because, ever since I was like 5 I have always wanted to succeed at school, and there’s the answer to my dreams. I also like learning about shape because I like learning things with some sort of challenge in them like, vertices (corners), edges, side and faces.

    I the picture I can see a cube, a pentagonal prism,
    A hexagonal prism I think and lots more.

    Have fun reading my comment.

    See you later,
    Libstar :mrgreen:

  12. Hi 4KM and 4KJ
    In the photo I can see a cube a hexegon a pyrimid a triangular prism a cone and a square based pyramid

    but no I have not gone on wood lands yet but I will
    got to go good bye 🙂

    • Dear kayley,
      Yes you are right I can see a Cone, Triangle, Square Based Pyramid ,Triangle Prism,Cube , Hexagon,Pentagon and Pyramid
      I also have not been on the Shapes woodland
      Well got to go bye for now

    • Dear Kayley,

      Thank you for leaving the comment on the blog! It’s ok that you haven’t been on woodlands yet,( I haven’t been on there yet. :oops:)

      Your right, I can also see all of the shapes you said in the comment.

      From your blogging buddy,
      Iesha 😀 :mrgreen:

  13. Dear 4KM and 4KJ,

    What a great post about what we are learning. Ok now I am going to type what I think the words mean,

    . A 3D shape is a 3 dimensional shape that has width, length and height.
    . A 2D shape is a 2 dimensional shape that has width and lenght.
    . A regular polygon is a shape with 3 or more sides that are all equal.
    . A prism is a 3D shape that has 2 identical bases. The rest of the sides are rectangles.
    . A pyramid is a 3D shape that has a base and more faces which are triangular.
    . A vertice is another word for corner or another word is vertex.
    . A edge is one of the sides of a polygon.
    . A face is a side of a prism or pyramid.(I think)

    Ok now lets move on to what I can see in the picture. I can see a:

    . A cone
    . A pentagon
    . A square based pyramid
    . A cone
    . A cube

    Sorry it is short, but I have to go!

    From Chloe

  14. Dear 4KM and 4KJ,

    Wow what a great post.Like all of the other posts, of corse! :mrgreen:

    My awnser for your first question is a square pymid, a cone, a cube , a tringleular prism , a pentagonal prism and a hexagonal prism!

    I also went on the Woodlands sites and I really liked 3D shape propidies. I didn’t play any other games, but I’ll try some of the games soon!

    • Dear Liv,

      What a wonderful comment! You truly are a fabulous blogger.

      I agree that this is a terrific post! You are right, just like all the other posts.

      You found lots of shapes! There are a heap of 3D shapes in that picture.

      I liked the games you did. I think Woodlands is a great site to put lots of game on. I played one other game, but it wasn’t as good.

      Your friend,
      Liv 😆

      I hope you enjoy playing the games!


    • Dear Harry,

      Your comment was very good and it is nice when we get comments from people in other schools then us.

      I have played the games and I liked them.
      Did you like them? What is your favourite game?
      Mine was the Match It game!


  16. Dear 4KM and 4KJ,

    Hi my name is Liam and I am in grade 3 at your school

    Great post.

    I know one of the shapes in the photograph it is a cube.

    In grade 3 we are leaning about time in maths.

    Can you please check out my blog here is the adress http://liamsblog.global2.vic.edu.au/

    From your new bloging friend

    • Hi Liam,

      It’s great to hear from one of my old students!

      I’m also happy to see you’re still blogging. I’ll have to check out your post.

      I hope you’re having fun with Mr Marshall.

      Your former teacher,
      Mrs M☀rris

  18. Dear 4KM and 4KJ,

    I found this post on shapes interesting. I can see in the comments you have been able to identify shapes and their properties so I couldn’t add anything to the skilled answers but I did start thinking about shapes and how we draw them.

    Many times my classes had looked at the properties of 2D and 3D shapes. I have also had to draw shapes very many times but some of my favourites include 3D shapes we might be able to draw on paper but they don’t make sense in the real world. Here are two “wrong” examples in a post if you are interested…

  19. @4km&4kj What a great post on Shape I like to Learning about Shape I thing it good for people to knew about 2D&3D Shape wont to knew what wood 4D like? From Ethan

    • Hello Ethan,

      We live in a three dimensional (3D) world so we see things in these dimensions only. Even when we draw 2D shapes like a square on paper, the paper is 3D and so is the pencil line.

      You want to know what a 4D shape would look like? I hope you have your thinking cap on because this is a little hard to understand. You have asked a very smart question. ☺

      What we call three dimensions (3D) means a shape has height, depth and width. It has three spatial dimensions.

      Scientists talk about a fourth dimension as being temporal (time) and not spatial (height, width, depth). Another group of scientists look at very small things, smaller than atoms. Some of them talk about many spatial dimensions maybe 10D, 11D, 26D or even more.

      Because we are 3D in a 3D world, we have so far found no way of showing or seeing all of these extra dimensions. The 4D using time is a little different but we can’t draw time into a shape. The 3D shows us where and the 4th D shows us when.

      I did say this was hard to understand so I can make this easier. I can’t draw a 4D shape. We only know 3D.

      • @RossMannell thanks for the reply Ross I look on Wikipedia I like 4 dimension shapes
        thanks for comment you are a good blogger From Ethan
