How do you use to two and too correctly in a sentence?

To better answer your question, first we should establish the difference between "to", "two", and "too": To refers to direction, position, and also forms the infinitive used before a verb. Two, of course, refers to the number 2, while too means besides or also, as well as excessiveness. Below are some example sentences.

• Would you give give this letter to Jessica?
• Bill went to the fair.
• I want to run a mile every day.
• What do you want to do now?
• I want two shirts for Christmas.
• I spent too much money at the store.
• I'm going to sell the couch and the table too.
• I bought two bags of sugar, but that was too much.
• I went to the store to buy two shirts, but it was too crowded.
