Some of the class had great fun making 3D shapes in the last two weeks. As a class we made a very large shape that has squares, triangles and pentagons as faces and has 60 vertices. The plans we used to create this called it a windball. We used some joiners from a construction set Mrs S had found called Makedo.
When we took our shape outside and put it on the grass. It did not roll at all. We decided that the cardboard was not rigid enough and the tufts of grass were too tall and caught in the open sections of the shape. When we put it in the asphalt area the wind blew it along very well.
When some of our class was competing in a sporting event the rest us made some 3D shapes using straws and pipe cleaners. The pipe cleaners were cut and bent to use as joins. We tried making a cube, tetrahedron, square pyramid and an octahedron. Just before we packed up Mrs S gave us 10 minutes to create the tallest structure we could. It had to be free-standing and we could only use straws and pipe cleaners. The tallest structure measured 86 centimetres.
Hi 4/5 DS
Your 3D shapes look wonderful! I especially like the “windball”. I have seen it through the window of your class quite a few times. Is the mathematical name for it a sphere or is that a complete ball with no gaps?
Keep up the good work!

Hey
I love your shapes. Was it hard?
Hi Jackson
No it wasn’t that hard. We just had to put a lot of clips into it and a lot of paper as well.

Hey its Max M
I liked your shapes, they were really cool!
Were they hard to make?
From Max M 5/6 W
Hey guys, nice big ball. I hope I get to make one in high school.

Dear 4-5D
You are really good at making 3- D shapes.
How did you make it? We did 3D shapes in term 2 as well. You can look at the photos on our blog but it is not our most recent post?
Bye for now,

Hi Alicia,
Thank you for your comment. We made the ball by putting cardboard squares together with joiners. The proper name for it is ‘Rhombicosidodecahedron’!
What is your favourite 3D shape? Ours are ‘Rhombicosidodecahedron’ and ‘Hexagonal Prism’.
Kind Regards
Phoebe and Jess
Hi3/4c
We made the 3-D shape using 30 pieces of cardboard, 60 joins and it had 60 vertices.
Bye.

Hi it is Brent from Upper Plenty.
The mystery skype was so fun.
I want to do it again.
Bye for now

Hi 4/5D,
You are really good at building 3D shapes and it looks fun. I wish I was there . It was really fun skyping with you today, and well done you guessed our school straight after we guessed your school. It was a bit tricky but we did it.
Bye

Hi Tayla-jade,
It is great fun and I enjoyed making the shapes! We are making a big Christmas tree now and we each get to make a small one. It was lots of fun doing the Skype and you were great at guessing our school! I would like to do another one with another school soon.
