I did a little research it is called chitting potatoes.

"Lay out your potatoes in a single layer on the floor, planting tray or flats and expose them to indirect sunlight. If you have a large amount, the trays can be stacked on rakes or similar, as long as there is good ventilation and equal light. Let the potatoes sit in that warm environment for a week or two, until the eyes start to sprout. The sprouts will start to green up and you should let them grow to at least 1/2 inch (13mm) long before planting."

I am still waiting for comments here too since I trust everyone!

Anyone?

Really, I just pop the whole little potato into the ground and wait for it to grow. You might get more plants overall cutting them, but the other is easier.

They might turn green if they are exposed to direct light. I would lightly cover them with something, possibly newspapers.
