I was born in Georgia, moved to the mountains of Virginia when I was 5. I now live in Northern Virginia. Where I learned to drive, if you lost control, you rolled down the mountain.
I agree with everything said here.
Go in an empty parking lot and do doughnuts to get to know the feeling when you first start to slide. Then practice counter-steering. It’s not as hard as it sounds, you simply steer in the direction you want to go.
In slippery conditions she should expect a little lateral slipping, but the main thing is to keep your cool and to keep going, making SMALL corrections when you start to slide. No sudden accelerations or braking, changing directions gently and only when you have to. If you skid, recover gently WITHOUT HITTING THE BRAKES, if at all possible. Keep a LOT of distance between you and the car in front.
If you have to drive in rolling hills where the road forms a “V”, make sure you have enough speed going down the hill to get up the other side. Again, you need plenty of space between you and the car in front - it would be a pity if you built up a good head of speed and the car in front of you didn’t, and started to slide around. If possible, hang back before making your run, to see how they’re going to fare.
If conditions are icy but there isn’t a snow bank on the side of the road, and you start to slide out going up a hill, you can sometimes get up the hill if you drive with your passenger-side wheels on the grass. Often icy grass will give more traction than icy pavement. But don’t drive with all four wheels on the grass, because the ground may be wet and soft.
Make sure you have at least All-Season tires on the car. In areas with a lot of annual snowfall, you may want to consider snow tires or perhaps even chains (if local ordinance allows). You should never drive chains on pavement, so that’s really only an option if you’re in an area where the snow plows never clear down to pavement.
Know when to give up. Don’t try to drive in snow that’s too deep for your car. In other words, no more than 6-8 inches (depending on your skill) of loose snow for a front wheel drive sedan. 4 wheel drive SUVs and the like obviously do better in the snow.
All said, I actually enjoy driving in snow and ice!
