Introduce the selection by asking students the following questions:
1. How many eggs do robins lay?
2. What time of day do robins lay their egg's(Sunrise, Mid-Morning,
Afternoon, Evening, or Overnight)
3. Once the mother lays an egg, how long does it take to hatch?
4. How does a mother robin take care of her eggs?
5. Do all the robin's eggs hatch at the same time?
6. How long do baby robins stay in the nest after they hatch?
Invite students to use their prior knowledge about robins to respond
to the questions. Encourage students to predict answers to questions. Invite
add their own questions about a robin's eggs. (Activating Prior Knowledge,
Making Predictions and Asking Questions to Set a Purpose for Reading)
Have students scan the subheadings of the reading selection: Breakfast First,
An Egg a Day, Stopping at Four, On the Nest, Sharing Her Body Heat, The End of the
Egg: Hatching Out. Place each subheading on a separate piece of
chart paper. Have students predict, "where facts will be found" by
writing the questions under each heading. (Making Predictions to Set a
Purpose for Reading)
Read "The Story of Robin Eggs." Encourage students
up the text" by circling unfamiliar words, underlining key words and
phrases, and writing notes in the margins. Invite them to underline sentences
answers to the preview questions.
Revisit the text to answer questions listed prior to reading. Ask questions
to facilitate student'swork: Which questions were answered by details in the text? What
facts did the article reveal about American robins and their egg'sInvite
students to generate more questions for further research about robins and their eggs.
(Rereading for Text Details)
Have students reread the selection with a partner. Invite
them to sequence the events of a robin's breeding cycle: migration, territory, courtship, nest building,
egg laying, incubation, hatching, and care of young. Have students summarize
(orally or in writing) key ideas from the text using the sequence of events. (Sequencing
Events Described in the Text, Summarizing Main Ideas in the Text)
Have students reread the selection to explore cause and effect relationships revealed
in the text. Invite them to complete the following sentence starters using facts
from the reading selection: (Exploring Cause and Effect Relationships)
1. Robins probably
delay their egg laying until midmorning so that?
2. Robins lay only one egg per day because?
3. Until they have laid a full clutch, robins allow all the eggs to stay cool
4. A mother robin gently rotates the eggs several times
a day so that?
5. Female robins have a brood patch because?
Journaling Questions (Making Inferences, Drawing Conclusions)
1. Why is it important for mother robin to keep her
brood patch hidden when she's
not sitting on egg's
2. Why do you think most birds lay their eggs in the morning rather than in the afternoon
3. Why do you think four is the best size for robin clutches?
4. What reasons can you think of to explain why robins time their egg incubation
different from hawks and owl's
Making Connections: Reading to Learn
Birds that lay eggs in nests or on the ground usually
lay colored eggs. Birds that lay their eggs in cavities usually lay perfectly
white eggs. Find a book with pictures
of different kinds of bird's eggs. (Making Text-to-Text Connections, Making
Inferences, Drawing Conclusions)
1. Why do you think most eggs are colored?
2. Why do you think the eggs laid in cavities are white?
3. Can you think of a reason why robin'seggs might be blue?
Evaluating(Identifying and Analyzing Text
Authors make decisions about how to present information to readers. They choose from
a variety of structures to organize facts. Have students identify which of the following
text structures can be found in the reading selection. Encourage them to give examples
from the text to support their answers.
Chronological/Sequence: (Time/Order) Chronological articles reveal events
in a sequence from beginning to end. Words that signal chronological structures include:
first, then, next, finally, and specific dates and times.
Cause/Effect: Informational texts often describe cause and effect relationships.
They describe events and identify or imply causal factors.
Problem/Solution: The text introduces a problem and describes solutions.
Compare/Contrast: Authors use comparisons to describe ideas to readers. Similes,
metaphors, and analogies are used in compare/contrast organizational structures.
Description: Sensory details help readers visualize information.
Directions: How-to texts frame the information in a series of directions.
use sensory details to write descriptively. What would a robin's
egg look like (color, size, shape)? What would a hatching egg
sound like? How does a robin's egg feel (texture, temperature)?
Collect sensory details to describe robin eggs in a nest. Use
the sensory details to write sentences that evoke vivid images
a magazine article that explains the events of a robin's breeding
witnessing baby robins hatching from their eggs. Write down your
thoughts and feelings about this wondrous event.
authors use creative strategies to write about facts for kids.
When writers create animal characters that talk, they are using
a strategy called personification. Rewrite the article from a
mother robin's point of view. Use personification to help readers
learn about the facts of a robin's breeding cycle. Be sure to
keep the facts accurate so that young readers will learn about
actual events in a robin's life.
