Other Forms of Explanatory Writing

Start-Up Activity

Ask a student to explain how to get from the school gym to the library (how-to). Then ask a different student to explain the difference between the gym and the library (comparison-contrast). Finally, ask a third student to explain why the school has a gym and a library at all (cause-effect).

Point out that the same topic can have different explanatory purposes. If you wanted to understand the difference between the gym and library, you would not be satisfied for someone to explain how to get from one to the other. In this chapter, students will learn how to write to these other explanatory purposes.

Think About It

“Grown-ups never understand anything for themselves, and it is tiresome for children to be always and forever explaining things to them.”

—Antoine de Saint-Exupéry

Writing Guidelines: How-To Essays

Help students brainstorm ideas for topics. Have them create lists or clusters (see page 32) in order to think about processes they could explain in an essay. Ask students to select a specific topic to write about.

Then, have them gather details about their topics, including any materials, tools, or equipment that are needed. Students can also list the steps in order and create a focus statement.

When they are ready, have your students draft their essays, using the model on page 178 as a guide. Then review the revising and editing checklist to help students improve their drafts.

Comparison-Contrast Essay (Continued)

After your class finishes reading the comparison-contrast essay, direct their attention to the “Patterns of Organization” graphic at the bottom of the page. Explain the three main patterns for comparison-contrast:

  • Point-by-point organization addresses one point of comparison or contrast for both subjects before going on to the next point.
  • Subject-by-subject organization fully discusses one subject and then fully discusses the other.
  • Similarities-differences organization highlights the way both subjects are similar and then ways both are different.

Let students know that they should choose whichever style best fits the subjects and the comparison-contrast.

Writing Guidelines: Comparison-Contrast Essays

Have students create a cluster around the nucleus words “My Interests,” surrounding it with topics that they really enjoy. Have them pick two interesting topics with some similarities and some differences.

Next, have your students research their topics by creating gathering grids. In the first column, they should write questions. The second and third columns should contain information for each of the two subjects. Students can answer each question for each subject and can research answers they aren't sure about. Download and distribute the gathering grid template.

If you prefer, you could have students create Venn diagrams to gather their details. (See the related minilesson.)

Cause-Effect Essay (Continued)

After you finish reviewing the cause-effect essay, preview the “Patterns of Organization” that students might use. Explain that sometimes multiple causes lead to a specific effect. At other times, one cause leads to multiple effects. Students will need to structure their essays based upon whether their analysis is cause-focused or effect-focused.

Writing Guidelines: Cause-Effect Essay

Ask your students to name some changes they have seen recently in their school or neighborhood. When they suggest changes, ask them what caused the change. Some changes have one clear cause, but others have multiple causes. Then ask what the effects of the change have been.

After this discussion of change, have students create topic charts focused on “change.” You can assign a general subject area, like “Changes at School” or “Changes in American Culture,” or you can let students select the changes they want to explore. Download and distribute the topics chart template.

Once students have selected topics for their cause-effect essays, have them conduct research to gather information about their topics. You can also use the related minilesson to help students gather information about their topics.

Responding to an Explanatory Prompt

Ask students to use a hand or piece of paper to cover everything below the prompt on page 189. Have them then read the prompt to themselves and use the PAST strategy to analyze the prompt. After they have jotted down the Purpose, Audience, Subject, and Type of writing, have students check their answers against those in the book.

Then direct students’ attention to the “Planning Quick List,” pointing out that the writer of the response quickly organized ideas before beginning to write. Have student volunteers read each paragraph and any side notes with it.

Writing Guidelines: Explanatory Prompt

Remind students how to use the PAST strategy to analyze a writing prompt, and then give them to following explanatory prompt:

An old expression claims that you don't really know something until you have to teach it to someone else. Think of a concept you learned recently in one of your classes. Imagine having to teach that concept to another student who missed class that day. How would you do it? Write an essay that introduces the concept and teaches it to another student. Make sure to use facts, examples, and even a definition or two to make the concept clear.

Now, have students use the PAST strategy to analyze the writing prompt:

  • Purpose: Teach and explain
  • Audience: Another student
  • Subject: A concept you learned in a recent class
  • Type: Explanatory essay

Tell students that they are going to practice on-demand writing by responding to that prompt. Lead them through the page, set a time limit, and get your students writing.

After students are done, they can trade papers with partners and use the revising and editing checklist for a peer evaluation of the writing.
