Class 7th We are still alive...

At the beginning we study the countable and the uncountable. How to differentiate it? and How to use it in the everyday? What is countable or uncountable? The teacher taught us to difference the countable from the uncountable. A object is countable If can it count piece for piece. Example: Orange, eggs, pencils, books… A object is uncountable If can´t it count piece for piece. Example: Sand, money, time, milk… example: she doesn't want many children he doesn't earn much money.
