Review the skill instruction for main idea and details on
p. 150. Write the following on
the board:
Main Idea = the most important idea; Details = little bits of information that
support the main idea. Students can complete Practice Book 3.1, p. 58 on their own, or
you can complete it as a class. Point out that the boxes in the main idea and details
graphic organizer are empty; students must fill in the boxes with information from the
passage.
Have students work in pairs to identify the main idea and one supporting detail on
p. 161.
(Main idea: The father penguin takes care of the egg and newly hatched chick;
supporting detail: He keeps the chick warm in his brood patch.)
For additional instruction of main idea and details, see
DI•52.
Graphic sources are any graphic—charts, graphs, diagrams, time lines, scale drawings,
and so on—that accompanies a selection. They can strengthen our understanding of
the text.
Point to the time line on
pp. 164–165. Discuss the information it contains and how
it helps them understand the selection better.
Have small groups of students create a time line that shows the growth of a human from
1 month to 5 years.
