Some background
Four years ago I created Google Earth resources for the classroom and
posted them to the GE Community Forum. Two of them were
called Maths in Madrid and Maths in Las Vegas.
These were based on the fact that there is maths all around us, every day,
everywhere we look. Google Earth (and Maps) gives us a great perspective on it
all. It also provides easy access for our students to see rich visual content
that depicts everyday maths. I have always loved the idea of children seeing the
maths they are working on.
The only issue with Google Earth is that it is restrictive in two ways. It is
not browser based and it is impossible for me to create a resource for others to
collaborate on.
