What's the Shape?

In Math, we have started to investigate shape, and have been exploring the characteristics of polygons.  After looking at many polygons, we decided that a polygon is a closed shape with straight lines that do not cross.  A polygon’s lines only touch at endpoints, or vertices. 

We use Power Polygons to combine shapes in various ways to make new polygons.  Today, we made 3, 4, 5 and 6 sided polygons. 


Alan combined Power Polygons to make a 3 sided polygon, otherwise known as a triangle


Alastair has made a 4 sided polygon.  Four sided polygons are called quadrilaterals.  This quadrilateral has 4 right angles, 2 long sides and 2 short sides.  What do we call this kind of quadrilateral?


Svea used triangles and parallelograms to make a quadrilateral.


How would you describe this polygon?  Leave a comment on our blog!

  1. I thought it was cool to envent these sort of shapes, some of the shapes was really cool for example the one right below svea.

  3. I think many peopke had very creative shapes. It was not very hard but it wasnt that easy. I think that making different power polygon was very fun.

  4. It is not a a quadrilateral!
    Because it doesn't have 4 sides.(It has 6 sides)
    I really enjoy using the "power polygons"
    But I enjoy more making our stories! "Comander Silly Socks" that's my character!

  5. I think that making shapes was a good idea because it was nice to listen, share ideas and emotion with our partner.

  6. i like how people are so creative in there shapes. lots of people made quadratills but some made really creative ones.

  7. I thought it was fun to make polygons like we did there.

  8. This polygon has 6 sides and made of triangles, paralleograms, 1 big square and 2 trapeziums.

  9. I think it was really fun to make polygons because I was really thinking about how to make polygons.

  10. That polygon looks like a 2-side pencil! That shape is very creative. I wonder who made it.
