Because to, too, & two all sound the same, people often confuse them. Here are some examples of how to use these words correctly.
To is either used as part of an infinitive (to go, to sing, to do, etc.) or as a preposition (to the store, to Rome, etc.). We use infinitives after certain verbs such as love, like, want, or hate. For example, "I want to see a movie tonight," or, "I hate to study for math tests." We use to as a preposition when we are talking about where we are going. For instance, "She is going to a party this weekend," or, "Did you go to the bank today?"
Too is used to talk about the quantity of something (too much, too little, etc.). As an example, "Jeff can't go with us tonight. He has too much work to do!" In addition, we use too when we mean also. For example, "I like the band Coldplay, too!"
Two is used to talk about the number between one and three. For example, "I have two sisters," or, "There are two tickets left for the concert on Saturday."
