Write an informative explanation with facts and definitions

Learning goal: Write a complete explanation that introduces a topic, develops it with facts and useful definitions, and closes with a statement connected to the topic. An explanation helps a reader understand something. Its main purpose differs from asking the reader to agree with a preference.

Source card — The classroom return station: This invented classroom keeps borrowed drawing tools at a return station. A station is a place set aside for an activity. The station has two labeled containers. The wide tray holds rulers. The tall cup holds pencils. At cleanup time, students put each tool in its matching container. A picture beside each label shows the tool that belongs there. The teacher checks the station after cleanup.

Read the source card twice. On the first reading, ask what the whole card is about: the classroom return station. On the next reading, find information that would help a new classmate use it. The two containers, their contents, the picture labels and cleanup time all help explain the system. The passage does not tell us the number of rulers or pencils, so a writer should not invent a count.

Plan with three questions: What is my topic? What should my reader learn about it? How can I finish the explanation? A useful beginning is “Our classroom return station is a place for borrowed drawing tools.” This introduces both the topic and its purpose. A reader who has never used the station now knows what the piece will explain.

Develop the topic with accurate facts. “Rulers belong in the wide tray, and pencils belong in the tall cup” describes the arrangement. Add a definition if it helps: “A label is a written name that tells what belongs in a place.” Explain how that definition fits this example: the station's labels and pictures show where to return each tool. A definition should clarify a word, not simply repeat it, as in “A label is a label.”

Group related information so the reader can follow it. First introduce the station, then describe the containers and labels, and then explain cleanup. If the writing jumps from cleanup to the cup to the opening topic and back to labels, reorganize the sentences. Facts can be accurate individually while their order still makes a piece harder to understand.

Complete model: Our classroom return station is a place for borrowed drawing tools. The wide tray holds rulers, and the tall cup holds pencils. Each container has a label, a written name that identifies what belongs there. A matching picture helps students find the right container. At cleanup time, students return the tools, and the teacher checks the station afterward. The station gives our tools a named place to return.

The final sentence closes by returning to the station's purpose. It does not add a new paragraph about recess or end with an unrelated opinion. A conclusion can summarize the information or explain why the described arrangement matters. It does not have to begin “In conclusion” or repeat the first sentence word for word.

Check the difference between a fact and an unsupported addition. “The cup holds pencils” is supplied by the card. “There are ten pencils” is not supplied. “The return station is the prettiest place in school” is a preference that does not develop the explanation. Use the supplied information to answer the reader's likely questions rather than make the piece longer with guesses.

The diagram labels the wide ruler tray and tall pencil cup. It illustrates which type of tool belongs in each container. Its few tool marks are examples, not an inventory count. When you make your own diagram, give each container a clear label and explain it in the writing. A useful picture supports the information; it does not replace the required complete explanation.

Worked plan: Topic: the return station. Point one: what belongs in each container. Point two: how labels and pictures help. Final idea: tools have a known place at cleanup. Turn these notes into sentences instead of submitting the notes as the finished text.

Worked improvement: “There are things there” becomes “The return station has a wide tray for rulers and a tall cup for pencils.” The revision names the place, containers and tools. It answers questions the first sentence leaves open.

Worked source check: A draft says students check the station before lunch. The source says the teacher checks after cleanup. Revise the person and timing to agree with the source; do not treat an invented detail as a new fact.

Guided practice: Identify the model's introduction, two facts, definition and conclusion. Explain what each contributes to a new reader. With a partner, plan an explanation of a different familiar classroom system, checking the actual arrangement before describing it.

Independent writing: Write your own return-station explanation using the card, or describe a real system after observing it. Include an introduction, accurate facts, at least one useful definition and a connected conclusion. Add a labeled drawing. Read the piece to someone who has not seen the system and ask what is still unclear.

Feedback: Assess the actual whole text for topic clarity, accurate development and closure. Check whether the definition clarifies its word and the illustration agrees with the prose. A learner may dictate their own composition with support recorded; filling in isolated labels or copying the complete model is not independent informative writing.
