Need to Light up LEDs with ref to thermistor

Hi there,

I am new to all this stuff, I have a very basic circuit I need to make and run off this board.
Basically I have a thermistor (reads temperature) which is a 2k2 type. I need to light up 4 different LEDs depending on temperature of the thermistor (resistance). So 1 LED needs to be lit up at a time which would reference what temperature zone it is in.
I really have no software experience and just trying to learn all this stuff so any help would be much appreciated.

What would be the most simple way to achieve this?

Horray for search engines!

Either fiddle with math or manually probe for certain values out of the analogread function and then digitalwrite() as needed.
