How does one know when to use the word too in a sentence?

Answer

"Too" is an adjective which references an overabundance of something--for instance, too much chocolate, or too many questions.

"To" is preposition which, among other things, designates to whom or where something is directed; for instance, give the chocolate to John; or, I am going to the store.

The way I have always remembered which is which is by thinking of TOO in terms of being TOO much of something, that's why it has the extra O.

Answer

You use to when you say things like "I want to go" or "That will need to be put away" you use too when you say things such as, "I want to go too." (takes the place of also, or as well) Too can also be used for expressing an abundance of something like, "I am too tired". Or you can say, "it is too!!!" if someone tells you it isn't. ;-)
