look for details that the author includes to make a point about the topic.For example,on page 16,the author states that the Amazon is a treasure and that it provides oxygen for human and animal survival.These details show me that the author believes the Amazon is a special and very important resource that is worth taking care of and protecting.Havestudentsworkwithapartnertorereaddifferent

ActivitiesBuild SkillsGrammar and Mechanics:Sentence types Explaintostudentsthattherearedifferenttypesofsentences that they will encounter when they read and as they write.Explain that one type of sentence is called a complex sentence and that a complex sentence contains an independent clause joined by one or more dependent clauses.Select a simple sentence from the text and record it on the board,for example,An ant quietly walks across your shoe.Invite students to identify the subject and verb in the sentence.Explain that this is a simple sentence because it has one phrase that contains a subject and a verb.Have students work with a partner to locate other simple sentences within the text.Point out that sometimes a sentence can have two parts,called phrases or clauses.Explain that each clause has its own subject and verb and that the clauses are joined together by conjunctions.Provide examples of conjunctions for students.Provide an example of this from the text and record it on the board,for example,The understory is not nearly as busy as the canopy,but animals do live here.Have students work with a partner to identify the conjunction,then have volunteers share with the class.Writethefollowingsentenceontheboard:Somewhere in the Amazon,the scream of a howler monkey echoes through the forest.Underline the scream of a howler monkey echoes through the forest.Explain that this part of the sentence is called the independent clause.Explain that the part of the sentence before the comma is called the dependent clause.Point out that even though both sentence parts contain a subject and a verb,the dependent clause does not express a complete thought and is not a sentence on its own.Have students locate and reread the third sentence of the second paragraph on page 15:When a big tree falls,they munch it down to small pieces.Invite a volunteer to identify the conjunction and the dependent clause.Point out that in this example,the dependent clause comes first in the sentence.Check for understanding:Have students work with a partner to reread page 9 to locate a complex sentence.Have students identify the independent and dependent clauses as well as the conjunction.Have students share their findings with the class.Independent practice:Introduce,explain,and have students complete the sentence types worksheet.If time allows,discuss their answers.WordWork:Homophones Havestudentsturntopage4andrereadthefirstsentence on the page:There is a place where monkeys swing and howl.Writethewordwhere on the board.Ask students to suggest a definition for the word where.Writethewordwear on the board.Ask students how this word is different from the word where (it is spelled differently and has a different meaning).Explain that two words that sound the same but are spelled differently and have different meanings are called homophones.Invite volunteers to use each word in a complete sentence.Writethewordone on the board and invite a volunteer to use it in a complete sentence.Then have student turn to a partner and think of a homophone for the word one(won).Have students share their findings and use the word won in a complete sentence.Havestudentsturntopage9andrereadthepagewith a partner.Invite them to highlight the word four in the first sentence and circle a homophone located on the same page(for).Have students share their findings with the class and use each homophone in a complete sentence.Check for understanding:Have students work in pairs to reread page 10.Invite them to create a list of words from this page with accompanying homophones.Have each group share their findings with the class.Independent practice:Introduce,explain,and have students complete the homophones worksheet.If time allows,discuss their
