Measuring resistance using analog breakout

Our team is interested in using sensors that change the resistance of a wire based on an input. We read the datasheet for the Analog Breakout and it included instructions for reading a potentiometer, which has three wires, so that there is a constant resistance between the +5V and GND and a variable resistance between both (+5V and SIG) and (SIG and GND). But what if a sensor only has two wires, and simply adjusts the resistance between them? Do we wire +5V to SIG through the resistor, or SIG to GND, or something more complicated?

Thanks.
