When explaining transition words to elementary students, you need to tell them it is like “going with the flow.” It makes writing interesting and moves it along. It is important to use more than one transition word or your writing will sound boring, like: “I saw the dog. Then I pet the dog. Then he ran away. Then I went home.” It would be much better to say: “I saw a dog and then began to pet him. Soon he ran away, so I went home.” The text was improved by putting short sentences together and using transition words.
Transitions can be used in diverse circumstances. A transition can be a word, a phrase or even an entire paragraph. The function of a transition is the same in each case: it summarizes the content of the preceding paragraph or section and it helps the reader anticipate what’s to come in the next paragraph. However, the major function is not just to embellish one’s writing by making it read or sound better; these are words which serve the function of presenting the ideas in such a way that help the readers react in particular ways to the ideas presented. They play a very important part in helping the readers see the logical sequence of the idea.
