Billions maybe even trillions.

Well, by some estimates there are 100 billion (1 x 10^11) stars in our galaxy. How many galaxies are there? Well, some estimates are about 1 x 10^11 galaxies. That gives something like 1 x 10^22 stars.
Of course, many galaxies have more or fewer stars, but that is a very rough estimate
It is still a huge number.

There are around 200 billion stars in our own galaxy -- we don't know exactly how many because a lot of the galaxy on the other side of the galactic center is hidden from our view by dust and gas that we can't see through very well.
EVERY single star you see in the night sky is in our own galaxy. We can see lots of other galaxies (a few of them, like the Andromeda galaxy or the Magellanic clouds you can even see without a telescope) -- there are many billions of other galaxies in space, each with similar numbers of stars to our own galaxy. While we can see these other galaxies, we can only make out individual stars in a few hundred of the closest ones -- the others are just too far away to resolve stars. But, even though you can see the individual stars in those galaxies, they *are* in our sky...
Stars in the sky (from our own galaxy) that you can see with just your eyes? A few thousand. That you can see with a small telescope? A few million. That you can see with a large telescope? Billions. That are in other galaxies (still in our sky) but we can't see directly? Many billions of billions.
It's a big universe :)

On a clear night at a dark site, a normal human eye can see about 5000 stars.
As pointed out above, there are 100 billion stars in the Milky Way, which is a typical galaxy. There are around 100 billion galaxies within our event horizon. Beyond our event horizon, there may be an infinite number of stars.

There are billions and billions of stars in the "sky".
Being able to see them is a different story. If you live in the inner city, the light pollution might be so strong that you can only see sunlight reflected off nearby planets. If you're standing outside of NoWhere, Montana on a clear night, you should be able to see several thousand stars with the naked eye.

On a clear, dark night away from lights you can see 3,000 naked eye stars. There are around 400 billion stars in the Milky Way Galaxy. There are countless number of stars in the Universe.

I learned in school that there are as many (or more) stars in the sky than grains of sand on earth

A recent study placed the total number of stars in the entire universe (..not just our Milky Way Galaxy..) at about 70-sextillion http://www.abc.net.au/science/news/space/SpaceRepublish_910295.htm
The total number of stars in the Milky Way is between 250- to 350-billion

They are infinite which means they are beyond count but I will help the best I can and start counting them. 1,2,3,4,5....hold on getting coffee.
Back, 6,7, 8, 9....do NOT go away!!! This can take a while! 10, 11......... Thanks alot! Now, I am going to be counting forever. Bet your next question will be how much sand grains are there and to tell you the truth I will be dead long before I can get to that one even if I live a million years just to count stars. Okay, where were we? 12, 13, 14....You have ruined my life but that is okay as I count and count and count!

There are no stars in our sky. However in space, beyond our atmosphere, there are countless BILLIONS of stars and more forming every day. Not to mention the ones dying every day.
