too quickly or too slowly.• That way, they do not make mistakes with

punctuation marks, or mispronounce words.• As you read, you should:

– take you time and read at your own rate.– not skip words and punctuation.– ask for help with pronunciation, if needed.– correct any mistakes you make while reading.

Fluency• I am going to read part of “Antarctic Ice” aloud.

I am going to read at a comfortable rate so I don’t skip any words or punctuation marks. If I make a mistake, I will correct it and continue my reading at my own pace. Listen to see if you think that makes my reading easier to understand.

Sequence: Comprehension

Blizzards A blizzard is a severe winter storm dangerous, harsh, and terrible.

Winds howl at 35 miles per hour or more, and the temperature drops. To make it worse, wind whips the snow around so rapidly that it becomes almost impossible to see more than a few yards in any direction. How does a blizzard get started? First, a mass of cold air moves south from the Arctic. Next, this cold air meets the warmer air around it and forces that warmer air to rise. Then, as the warmer air rises, it creates a cold front. Finally, when all this has happened, heavy snowfall begins.

The most violent form of a blizzard is a whiteout. It is called this because snow if blowing around so much that people cannot tell the difference between the ground and the sky. Everything is white with snow. It is this combination of wind, cold, and blinding snow that makes blizzards so dangerous. They can cause car accidents, trap people inside vehicles and buildings, and even crush homes under the weight of heavy snow. It is no wonder that people listen carefully when blizzard warnings are given.

Sequence: Comprehension

• What is the first step in the forming of a blizzard?

• A mass of cold air moves south from the Arctic.

• What else happens before snow begins to fall?

• Cold air forces the warm air to rise, and this creates a cold front.

Compare and Contrast: Comprehension

• When you compare people, things, or even ideas, you tell how they are alike.

• When you contrast, you tell how people, things, or ideas are different.

• Clue words, such as same and both signal that things are alike.• Words such as unlike or but signal that things are different.• Comparing and contrasting can help readers better understand

expository nonfiction.• Teacher read aloud page 171.• As I read, I ask myself, “What do the penguins do in winter and

summer?” How is it alike and different? In winter and summer the penguins take care of their young. In winter the mother penguin lays one egg and the father penguin keeps it warm. In summer the chick is too big to sit on her father’s feet.
