Compare and Contrast Ideas
often connect unknown ideas with known concepts to help readers learn
about a topic. Compare/contrast instruction includes identifying author’s
use of comparisons and a reader’s ability to make comparisons.
A simile is a comparison of two unlike things that are
alike in one way; a simile uses like or as or a comparative adjective
and than. Examples: Butterflies are like flower petals
with wings. Migration is like a journey. Caribou feet are like snowshoes.
Metaphor: A metaphor is
an implied comparison between two unlike things. A metaphor does not use
a clue word. Examples: Butterflies are flower petals
with wings. Migration is a journey.
Analogy: An analogy is also
a comparison of two or more objects. The analogy implies that the objects
are alike in some ways. Examples: An orchestra of robins
welcomed the sunrise. Birds soar through highways in the sky.
