10、authors name).Ask students to turn to the table of contents.Remind them that the table of contents provides an overview of the book.Ask students what they expect to read about in the book based on what they see in the table of contents.(Accept all answers that students can justify.)Introduce the Rea

11、ding Strategy:Summarize explain to students that one way to understand and remember information in a book is to write a summary,or a brief overview of the most important information in the text.Point out that a summary includes the main idea and one or two supporting details.It often answers the que

12、stions who,what,when,where,why,and how.Model how to summarize.Think-aloud:As I read this book,I am going to stop every now and then to remind myself about the information I have read so far about volcanoes.Doing this helps me remember what Im reading and makes me think about new information.When I f

13、inish reading the book,I will be able to tell,in my own words,some of the information from each section about volcanoes that I have read.As students read,encourage them to use other reading strategies in addition to the targeted strategy presented in this section.Introduce the Comprehension Skill:Ma

14、in idea and details explain that sometimes the amount of information about a topic is so large that it is grouped into sections,and each section of the book has its own main idea.Write the following list of words on the board:volcanic mountains,plains,valleys,and oceans.Ask students to describe what

15、 these words refer to(landforms).Point out that the definitions of these words help to identify a main idea.(Many different landforms make up the topography of the world.)The words volcanic mountains,plains,valleys,and oceans are details that support this main idea.Model using the table of contents

16、to infer supporting details in the text.Think-aloud:When I look at the table of contents on page 3,I see that the word eruption is part of a section title.I already know that volcanoes erupt,so what happens when they erupt is probably a supporting detail in the book.When I read,I know that I will fi

17、nd out even more details about volcanoes.As I read,I will pause after every few pages to review in my mind the important details.This strategy will help me make sure I understand what Im reading.I know that good readers do this when they read,so I am going to look for supporting details as I read th

18、is book.Have students turn to the table of contents and list some of the supporting details about volcanoes(vesuvius,Composite,Lava Domes,and so on).Introduce the Vocabulary As students preview the book,ask them to talk about what they see in the photographs and illustrations.Reinforce the vocabular

19、y words they will encounter in the text.Model how to apply word-attack strategies.Have students find the word geothermal on page 22,and write it on the board.Point out the geo-prefix and explain that recognizing prefixes and suffixes can help students break up longer words and help them read these w

20、ords.Ask a volunteer what the root word is(thermal)and underline it on the board.Point to the geo-prefix and remind students how it is pronounced.explain that the prefix geo-pertains to the word“earth.”VolcanoesLesson Plan(continued)LeveLZ Z3 Learning AZ All rights reserved.www.readinga- Have studen

22、tudents that sometimes they will not find any context clues that define an unfamiliar word.Model how students can use the glossary or a dictionary to locate a words meaning.Have a volunteer read the definition for geothermal in the glossary.Have students follow along on page 22 as you read the sente

24、ading:Have students read to the end of the first paragraph on page 10(finishing the section).Ask them to remember to underline the important details as they read.encourage students who finish before everyone else to go back and reread.Model identifying the main idea and details.Think-aloud:As I read

25、 the first section,I noticed that most of the sentences mentioned something about the eruption of Vesuvius.I read that a huge explosion shook the ground in Pompeii on August 24,AD 79.I will underline this information in the book.I also read that dust,ash,and lava poured from the volcano,destroying e

26、verything in its path.Buildings collapsed and people died as they tried to flee the land.Eleven hours later,surge clouds fell down the mountain at speeds of 310 mph,and within moments,all of the people of Pompeii and Herculaneum were burned and buried by dust and ash.When the eruption ended,two citi

27、es were completely gone.I will underline all of this information as well.Based on what Ive read and underlined,I think the main idea of the section is:When Mount vesuvius erupted in AD 79,the results were catastrophic.eleven destructive hours after erupting,two cities were completely buried and wipe

28、d off the face of the earth.Write the main idea on the board.Ask students to identify details that support this main idea.(Page 4:Roman city of Pompeii;AD 79;didnt pay attention to earthquakes;always rebuilt their city when damaged;thought Mount vesuvius was dormant or extinct;lived in Pompeii for c

32、l summarizing the main idea and details from the first section.Think-aloud:To summarize,I decide which information is most important to the meaning of a section.To do this,I can identify the main idea and important details and then organize that information into a few sentences.When I look at the ma

33、in idea and details on the board,a summary of this section might be:In AD 79,the people of Pompeii thought beautiful Mount vesuvius was dormant.But that year,its eruption caused catastrophic resultslava,hot ash,stones,and poisonous gas that destroyed all life.The powerful surge clouds that followed

36、nd Why volcanoes Form.”Write these details on the board.Divide students into groups and have them work with their group to identify the main idea from the details of the section.Discuss their responses as a class and write a main idea on the board.Ask each group to use the main idea and details of t

38、 a question mark in their book beside any word they do not understand or cannot pronounce.encourage them to use the strategies they have learned to read each word and figure out its meaning.After Reading Ask students what words,if any,they marked in their book.Use this opportunity to model how they

39、can read these words using decoding strategies and context clues.Reflect on the Comprehension Skill Ask students what words they marked in their book.Use this opportunity to model how they can read these words using decoding strategies and context clues.Discuss how stopping to review the important d

47、st of the sentence,to separate a list of three or more items,and to separate clauses within sentences.Write the following sentence on the board:Suddenly,a huge explosion shook the area around the mountain.Ask a volunteer to come to the board and circle the comma.explain that the word suddenly is an

49、 help them gather information about volcanoes.Ask a volunteer to identify the introductory word(today).Discuss the location of the comma.Read the sentence aloud,emphasizing how the comma sets off the leading thought.Next,explain to students that whenever a list of three or more items is made,a comma

50、 must be placed between the items.Listed items can be nouns,verbs,adjectives,or entire phrases or clauses.Remind students that this is only one of the many uses for a comma.Have students turn to page 14 and read the following sentence aloud:The crater is a hollow area where the magma,hot gases,and a
