A Brief Overview of Introducing Explanatory Writing

Explanatory writing is a type of informational writing that requires a student to write in an orderly, sequential fashion. This type of writing is sometimes also referred to as expository writing and it serves as an important step toward creating longer, more detailed research projects in the future.

Explanatory writing topics can include scientific prompts, historical ideas, current events, or social issues. Using an outline is extremely helpful for youngsters with this form of writing. In some cases, opinion pieces also can be a form of explanatory writing, as long as the student uses facts and data to back up their opinion on a given topic.

From early elementary grade levels, students are beginning to expand on their basic understanding of writing and learning how to convey the thoughts and ideas that they have in clear, concise ways. In the later years of elementary school, students should use explanatory writing frequently in the classroom to bolster their skills. 


If you are introducing explanatory writing to your students, you may find that this type of writing is a challenge for them. This is a new concept to students in third and fourth grade, but it’s important to help them work through their frustrations and create a piece that is cohesive and informative.

By the time they are in fifth and sixth grade, they will be so familiar with explanatory writing that they will naturally start to extend their pieces and create more intricate reports. Of course, into middle and high school, pre-teens and teens are refining those skills.

I hope you have your writers explore this excellent form of writing.
