A thesis statement is the opening and most crucial part of an essays or research paper. The point of a thesis statement is to let the readers know what the overall purpose of the paper or essay is and what your main arguments are. When you have three separate point that back up your argument, you can include each of them in your thesis statement. This is known as a three-point thesis statement, and it's an effective way to summarize an argument.

Step 1

Determine the argument you will make in your essay or paper. For example, you might be making the argument that TomTom GPS navigators are better than Garmin GPS navigators.

Step 2

Come up with three points that support your main argument. With a three-point thesis, you will need three supporting points. However, make sure you can back up those points with evidence. In the example provided, the three points could be that TomTom GPS navigators are cheaper, easier to use and have more features than Garmin devices. Remember, all of these points need to be backed up by factual evidence in your essay or paper.

Step 3

Start out your thesis statement by stating your main argument. In the example, this would be "TomTom offers GPS navigators that are better for consumers than Garmin GPS navigators because ..."

Step 4

Add the three points to your three point thesis statement. A final three point thesis might look like, "TomTom offers GPS navigators that are better for consumers than Garmin GPS navigators because they tend to be less expensive, are more user friendly, and offer more features than similar Garmin GPS navigators."
