II.KeyPoints&Difficulties

KeyPoints

GlobalIssuesandGeography:

Populationgrowth:From7billion(2010)toprojected9billion(2050).

Livableland:Only1/3oftheearthisland,withdeserts,mountains,andicelimitingwherepeoplecanlive.

Continentsandoceans:7continents(6livableexceptAntarctica)andoceanscovering2/3oftheearth’ssurface.

Vocabulary:

increase,dry,surface,billion,total–usedtodiscusstheearth’spopulationandgeography.

Difficulties

Explainingplexglobalissues(e.g.,populationgrowth’simpactonresources)clearlyinEnglish.

Accuratelyusinggeographyrelatedvocabulary(e.g.,“surface”todescribetheearth’scoverage)insentences.

Correctlymatchingcontinentswiththeirdiversedescriptions(size,countries,features).

III.TeachingMethods

TaskBasedLearning(TBL):Throughparagraphmainideamatching,vocabularyfilling,continentdescriptionmatching,andglobalissuediscussions.

MapBasedVisualization:Usingworldmapstolocatecontinentsandoceans,linkingtotextdetails.

CollaborativeLearning:Groupworkforcontinentdescriptionmatching,emphasizingpeerfeedbackonaccuracy.

IV.TeachingAids

CAI(worldmapanimations,vocabularydefinitions,continentfactcards).

Textbook,worksheets,and“GlobalIssueCards”(withtermslikepopulation,livableland).

V.TeachingProcedures

Step1:Warmup–OurPlanet’sBasics(5mins)

DiscusstheTHINKABOUTITquestions:

Howmanycontinentsarethere?Whatarethey?(E.g.,“Seven:Asia,Africa,Europe,NorthAmerica,SouthAmerica,Australia,Antarctica.”)

Whatdoyouknowaboutyourlivingplace?(E.g.,“Ilivein[city],partof[continent/country],with[localgeographylikeriversorhills].”)

Share:Invite3–4studentstoshare.Writekeywords:continents,home,geography,earth.

Step2:Prereading–VocabularyandMapPrep(8mins)

VocabularyIntroduction:

Teachwordswithexamples:

increase:“Theworld’spopulationisincreasing.”

dry:“Desertsaredryandhardtolivein.”

surface:“Oceanscovermostoftheearth’ssurface.”

billion:“Over7billionpeopleliveonearth.”

total:“Thetotalnumberofcontinentsisseven.”

MapActivity:

Showaworldmap,labelcontinentsandoceansasinthetext.

Step3:Reading–ExtractingGlobalDetails(12mins)

pleteLet’sDoIt!1(ParagraphMainIdeaMatching):

Answers:

Paragraph1:c(populationproblem)

Paragraph2:e(unlivableareas)

Paragraph3:a(sixlivablecontinents)

Paragraph4:d(oceancoverage)

Paragraph5:b(protecttheearth)

TextAnalysis:

Discusshoweachparagraphintroducesakeytopic(population→livableland→continents→oceans→earthprotection).

GlobalIssueDiscussion:

Ask:“Whyispopulationgrowthachallenge?Howdoeslimitedlivablelandmakeitharder?”(Linktotext:“Only1/3ofearthisland,andsomeisunlivable.”)

Step4:VocabularyandGrammarPractice(10mins)

SentenceExpansion:

Example:“Toprotecttheearth,wemustslowpopulationincrease,savedrylands,andcareforthesurface—foratotalof7billion+people.”

ErrorCorrection:

Fixmistakeslike“Thesurfaceofearth”→“Thesurfaceoftheearth”(articleuse).

Step5:GroupProject–ContinentDescriptionMatching(15mins)

TaskIntroduction:

Match7continents(Asia,Africa,etc.)withdescriptions(size,countries,features)usingtextdetails.

Example:“Asiaisthebiggestcontinent—hastheHimalayas.”

GroupWork:

Studentsdiscussandmatch,usingmaps/textforreference.Teacherguidesfactchecking(e.g.,“Africahaselephants—correct.”).

ClassSharing:

Groupspresentmatches.Feedbackfocusesonaccuracy(e.g.,“Asiaisthebiggest—textconfirms.”)

Step6:SummaryandHomework(5mins)

Summary:

Recapglobalissues(population,livableland),continents,oceans,andtheneedtoprotecttheearth.

Homework:

（1）Writea6sentencereflection:“WhyProtectingtheEarthMatters”(use3terms:population,continents,surface).

（2）Researchonemoregeographyfact(e.g.,“ThePacificOceanisthelargest”)andshareinclass.
