Moon, Earth's Best Friend

by Stacy McAnulty

In Stacy McAnulty’s nonfiction picture book, Moon introduces itself as Earth’s longtime companion, sharing facts about its history, surface, movement, and relationship with our planet. A playful first-person voice and Stevie Lewis’s expressive illustrations turn astronomical information into an engaging portrait of Earth’s nearest celestial neighbor.

Big Idea

An inviting voice can make scientific information memorable without changing the facts. Readers can distinguish Moon’s imagined personality from the real science behind its friendship with Earth.

Discussion Questions

1.Why do you think McAnulty lets Moon tell its own story instead of having a scientist explain it? How does that choice affect your reading?
2.In what ways is Moon like a best friend to Earth, and where does that comparison stop working scientifically?
3.Which fact about Moon surprised you most? How did the words or illustrations help you understand it?
4.How can we tell which parts of this book are scientific information and which parts are playful personification?
5.If you could ask Moon one question after reading this book, what would you ask, and how could we investigate the answer?

Lesson Plan

⏱ 45 minutes📦 A copy of the book, paper, pencils, crayons or colored pencils, chart paper, and optional sticky notes

Learning Goals

Identify at least three accurate facts about Moon using information from the book.
Distinguish scientific facts from personification in a nonfiction picture book.
Write or dictate in a consistent first-person voice while preserving scientific accuracy.
Use sentence length, punctuation, and illustration placement to influence reading pace.
Read a short original text aloud and revise it based on how it sounds.

Activity Steps

1.Read the book aloud, pausing at selected spreads to discuss Moon’s voice and the scientific information. Create a chart labeled “Moon facts” and “Imagined personality.”
2.Reread two contrasting spreads. Ask students where they want to linger and where they read quickly, noticing sentence length, punctuation, illustrations, and page turns.
3.Have students select three verified facts. Fold a sheet of paper into four panels: a Moon introduction, two fact panels, and a closing panel connecting Moon with Earth.
4.Students write or dictate Moon’s narration and illustrate each panel. Ask them to include one short, punchy sentence and one longer explanatory sentence; clarify that Moon reflects sunlight rather than producing its own light.
5.Partners read the mini-books aloud, pausing at panel boundaries. Each listener identifies a memorable fact and a place where the pace changes.
6.Students revise one sentence or illustration placement, then share their mini-books. Finish by naming one imagined character trait and one real scientific fact in each example.

Pace-Write-Read Study with Pace-Write It!

Moon, Earth’s Best Friend shows that pacing matters in informational writing, not just in adventure stories. McAnulty gives a real celestial body an imagined speaking voice, allowing scientific facts to feel like introductions, discoveries, and friendly explanations. In a Pace-Write-Read study, students can notice how brief statements, fuller explanations, humor, and illustrations change the speed of a read-aloud. The guiding question is: How does the author help us enjoy Moon’s company while learning about it? Begin by separating two layers of the book: its factual content and its playful presentation. Moon’s personality is a literary invention, while information about its surface, reflected light, and connection to Earth can be checked. Then reread selected spreads to investigate where the reader pauses, anticipates a page turn, or needs time to understand a scientific idea. Students can transfer these observations into short Moon-narrated texts, using pacing to highlight accurate information rather than to disguise or replace it.

Element	How to notice or teach it in the novel
Pacing	Compare a spread that introduces a quick fact with one that needs more explanation. Notice how the amount of text, picture detail, and read-aloud pauses affect the time readers spend with Moon.
Plot	Treat the book as a sequence of informational revelations rather than a conventional problem-and-solution plot. Track how readers’ understanding of Moon and its relationship with Earth grows.
Prosody	Read Moon’s narration with a friendly, conversational tone, adjusting emphasis to highlight important facts. Compare an expressive reading with a flat one and discuss which makes the information easier to follow.
Word	Select a scientific word from the book, such as “orbit” or “crater,” and examine the context that helps explain it. Ask how pairing precise vocabulary with familiar language supports readers.
Concept	Explore the central concept of Moon as Earth’s companion. Separate the friendship metaphor from the physical relationship between a planet and its natural satellite.
Voice & Worldview	Notice how Moon presents itself as a personable companion rather than a distant object. Discuss how this affectionate perspective invites curiosity about space.
Point of View	Identify the first-person narration and rewrite one fact in third person. Compare how “I” and “Moon” change the reader’s sense of closeness without changing the science.
Setting & Place	Use the illustrations to distinguish Moon’s surface from the larger Earth–Moon space setting. Discuss why location matters when explaining sunlight, movement, and distance.
Original Characters	Examine how McAnulty and Lewis turn an existing astronomical body into a distinctive character. Students can invent a personality for another space object while keeping its physical properties accurate.
Dialogue	Distinguish Moon’s direct address to the reader from a back-and-forth conversation. As an extension, write an invented Moon–Earth exchange and label it as a creative addition, not text from the book.
Details	Locate concrete details about Moon’s surface, history, or movement. Ask which details most strongly support the portrait of Moon as Earth’s longtime companion.
Descriptions	Compare what the words explain about Moon with what the illustrations let readers see. Invite students to describe a crater using both an accurate observation and an imaginative comparison.
Firsts	Notice the reader’s first introduction to Moon as a speaking character and discuss the impression it creates. Connect historical information about human visits to the idea of a first encounter, distinguishing people reaching Moon from Moon’s much older history.
Immediacy & Engagement	Ask how Moon’s direct, conversational narration makes a distant place feel close. Have students write an opening that immediately invites readers to meet Moon.
Story Scenes, Summaries & Structures	Compare illustrations that suggest a particular moment with passages that summarize long stretches of time or explain a general fact. Discuss why an informational picture book moves between these approaches.
Tension / Suspense / Surprise	Look for surprise in unfamiliar facts and humorous presentation rather than danger or conflict. Ask students which discovery changed what they previously believed about Moon.
Flashback, Flash-Forward, Cliffhanger	When the book discusses Moon’s early history, explain that the narration looks back in time. Do not assume it uses all three devices; students can experiment with a new page-ending question that encourages a turn.
Page Turns and Chapter Breaks	Study page turns as the book’s main reading divisions rather than chapter breaks. Before turning a selected page, ask what information readers expect next and how the following spread develops or changes that expectation.
Pace & Creativity	Use one Moon fact to create two versions: a quick announcement and a slower explanation. Compare which version best supports curiosity and understanding.
Play	Notice the playful choice to let Moon speak and have a personality. Invite students to play with voice while holding the underlying science steady.
Performance	Have students perform a short passage as Moon, using expression and purposeful pauses. Ask performers to make the meaning clear without adding statements that could be mistaken for scientific facts.
Personality	Infer Moon’s character traits from its narration and illustrated expressions. Support each inference with a specific word choice or visual detail.
Humor	Find a moment where Moon’s humanlike attitude or an illustration creates humor. Discuss how the joke helps readers connect with a real fact rather than replacing it.
Pause	Pause after a surprising fact or an explanation of reflected sunlight to give students processing time. Ask how that pause differs from a pause used to let a joke land.
Poetry / Poetic Devices	Explore personification in Moon’s narration and the friendship metaphor in the title. Discuss what these devices help readers imagine and what they do not literally mean.
Repetition	Track the recurring idea of Moon’s connection to Earth, whether or not the same wording repeats. Students can use a brief recurring phrase in their own mini-books to connect different facts.
Rhythm	Listen to how short statements and longer explanations create a conversational rhythm. Clap or tap the phrasing of a selected sentence, then test a student-written sentence aloud.
Punctuation	Inspect punctuation in a selected passage and connect each mark to a reading decision. Students can revise their Moon narration with punctuation that signals a pause, emphasis, or completed idea.
Questions	Collect questions the book raises about Moon, even when they are not printed as questions. Sort them into questions answered by the book and questions requiring further investigation.
Compare-Contrast	Compare Earth and Moon using facts and illustrations, considering their surfaces and their relationship. Keep the friendly characterization separate from scientific similarities and differences.
Objects	Focus on concrete features or objects shown in the book, such as craters and material associated with human exploration. Explain how a visible object can anchor an otherwise abstract explanation.
Threes	Have students choose three Moon facts to organize a short piece with a manageable rhythm. Present this as a writing strategy to try, not as a claim that the published book consistently uses groups of three.
Lists	Gather several facts from the book into a class list, then compare the list with Moon’s conversational presentation. Discuss when listing speeds up information and when explanation needs more space.
White Space & Negative Space	Examine relatively open areas around text and celestial objects in Lewis’s illustrations. Discuss how uncluttered space can focus attention and suggest the scale or openness of space.
Art & Graphics	Compare illustrations that communicate scientific relationships with those that emphasize Moon’s personality. Ask how words and pictures work together, and note that expressive drawings are not necessarily scale models.
Interactives & Gamification	Create a “fact or personification?” sorting game using statements based on the book. This is a classroom extension rather than an assumption that the book contains built-in games.
Placement	Study where text sits relative to Moon, Earth, and other visual information on a selected spread. Ask where students look first and how that starting point influences their reading.
Form	Identify the book as a nonfiction picture book with a personified narrator. Discuss how it combines factual explanation with techniques readers often associate with character-driven stories.
Dummy	Explain that a dummy is a rough book mock-up used to test page order and turns. Students can fold paper into a Moon mini-book and move facts between panels to improve pacing before making final illustrations.
Passion	Ask which aspect of Moon the book makes students want to investigate further. Encourage them to let that curiosity guide their writing while checking every scientific claim.

Pace-Write It!

20-minute Pace-Write-It! task: “Moon’s Slow Reveal.” Minutes 0–3: Revisit the book’s explanation that Moon reflects sunlight; distinguish this fact from its imagined speaking personality. Minutes 3–6: Fold paper into four panels and plan an introduction, a setup, a factual reveal, and a closing connection to Earth. Minutes 6–12: Write or dictate four to six sentences in Moon’s voice. Use a short setup before a panel turn and a fuller explanation afterward—for example, an original student model could read, “See me shining?” followed by “That light comes from the Sun. I reflect it.” Minutes 12–16: Add illustrations showing sunlight reaching Moon, with arrows labeled as a simplified model. Minutes 16–19: Partners read aloud, pause at the reveal, and check that the text never says Moon produces its own light. Minute 19–20: Revise one sentence or panel placement and share how the change affects the pace.

Classroom Activities

Moon’s Best-Friend Mini-Book

Students create a four-panel mini-book narrated by Moon. Using verified facts from the read-aloud, they combine an imagined friendly voice with accurate information about Moon’s surface, reflected sunlight, and relationship with Earth. They vary sentence length and panel layout to make one fact unfold slowly and another arrive as a quick surprise. Designed primarily for grades 1–3, the activity can use drawing and dictation for emerging writers.
