Hexagons

We've been looking at hexagons this week, and making our own using Geogebra and changing some using these Geogebra models.

One of the things we've looked at is what kind of angles they have at their corners.

Here's a slide show of some of our work:

My cat, Dizzy

My cat, Dizzy is  funny, cute and a little nutty . She is a black, short-tailed cat with a pink collar and amber coloured eyes. She can be a little nutty at times because she runs around, crashing into doors and chasing her tail like a dog...but she is still so adorable! Her full name is Dizzy Owens Meow The II. Her favourite things to do are to watch the bubbles in a glass of cola and sleeping. I think she is the best pet ever - I would also like a pug though!!!

Making Geostrips

Today we made geostrip hexagons.

Hexagons are shapes with 6 sides.  They are regular if all the sides are the same
length and all interior angles are equal.

The one above is not a regular hexagon.  It is irregular.  Can you see why?

Here are some more photos of us making our geostrip hexagons.

Making machines

We've been bringing in lots of "bits and bobs" ready to make fanciful machines. We wanted there to be moving parts. Rather than start off drawing, we had a look at all our material and in groups thought about what it might make. Not easy...
