Then I got a pensil and a rubber.
Now I own one of these.
Apparently it's called a protractor. I thought it was called a compass. That is, they tell me, a thing for making circles whereas a protractor is for measuring circles. I never thought I'd actually own one of these, you never know where your new found maths obsession will take you.
My protractor fits handily in my back pocket. So I can now measure as many angles as I want. I'm not sure why I would want to but I can. Maybe next time I pop round your house I'll be going round and finding all your angles as seeing just what sort of angles you have to offer.
"Ooooo..." I'll say "A hexanganal table do you mind if I just..."
I thought that Maths just needed a brain and maybe a bit of paper. How wrong I was. I also have one of these.
This is a special 'doing maths' ruler. It's seethrough which makes it easier to measure things rather than a 'not doing maths' ruler which doesn't have to be seethrough since it is just for drawing straight lines.
See! Look how much I understand now.
Admit it you're impressed.
What else will I need to get next?

What are 'not doing maths' protractors good for, I wonder?
A programmable calculator. Then one capable of numerical integration! POWER! MADNESS!
Squared paper/graph paper? Some of the tesselation (sp?) and colour theories can be fun.
Popping round to people's houses measuring their curves would be a lot more fun than measuring their angles :)
Slide rule.
How about a slide rule? They're good when you get into logs.
You'll probably need one after the Christmas lunch. ;)
a set square
