简介:本文档为《植树问题教学设计doc》,可适用于综合领域,主题内容包含植树问题教学设计植树问题,一,教学设计教学内容:植树问题(一)教材第,页例、课型:新授课授课人:李远芳例和第页的“做一做”教学方式:创设情境激发学习符等。

植树问题教学设计植树问题,一,教学设计教学内容:植树问题(一)教材第,页例、课型:新授课授课人:李远芳例和第页的“做一做”教学方式:创设情境激发学习方式:大胆猜想动手操作小单位:新生小学兴趣引导学习组合作探究知识、了解同一直线上植树问题的三种基本情况能阐述不同情况下棵数与间隔数的关系会正确解决类似的数学问题知识与技能教、引导学生用摆一摆画一画线段图的方法分析理解题学意体会植树问题的数学思想正确解决相关的植树问题。目通过摆一摆、画一画、比一比等方法经历对知识的探究过过程与方法标程让学生体验学习的方法培养学生一定的学习能力。体会数学知识在日常生活中的广泛应用培养学生的探究情感态度与价值观意识和能力受到热爱劳动、保护环境的思想品德教育。能阐述不同情况下点数与间隔数的关系教学重点能根据不同情况选择正确方法解决问题。教学难点课件、小树图片、纸条、答题卡教学准备小树、纸条等学具准备教学过程教学内容教师活动学生活动设计意图创设情境:同学们在上课之前我们先来学生看到水土流情境引观看水土流欣赏一些图片欣赏完之后要失、泥石流沙入激发失、泥石流说出自己的体会。播放课件中尘暴等图片后感学生的学一、创设的图片沙的水土流失、泥石流沙尘暴等受到保护环境的习兴趣情境引入尘暴等图图片引发学生思考:环境被破重要性提出我对学生进课题片体会要坏后会给人们带来哪些灾难们要植树造林。行环境保保护环境如何保护环境。其实在植树里护教育从而要植树面藏着许多的数学问题今天为后面的造林。我和同学们一起来研究植树学习铺路问题板书课题。villagetemplesCentralOfficeeveryday,carryouttheirdutiesCorrespondencerelatingtoeducationbytheChiefofthefirstsectionmarkedmydraftstatementWorkedafterafewmonths,I'vebeenburiedintheofficialprogram,veryrigidmonotonyofclericalcareer,flavourlessofAugustbetween,County,andSecretarytoIwithtoOfficemeeting,forGovernmentestablishedoneyearstoworkreported,fortintmatters,Iaccordinglydetailednarrativefinishingwritten,completedWujiangGovernmentestablishedoneyearstoofworkreportTurnbackandforthmonthShanRoad,apartfromtheSecretary,Mrrankfootdiseaseimmobility,bamboocarinsteadofwalkingoutside,squarefoot(exceptformyselfandguards),thewuxing,peace,SIan,Guangde,doorwayswing,ZhangZhutothedestinationwearingBuAtdiweitotheimportanttownsoftroopsisdifficulttoaccess,wehavetochangeangles,Shanruggedtrails,Sunandrainontheway,hardshipexceptions,ifthepatrioticandpassionsofthewar,thanthesuccessfulcompletionoftasksAnoldfrail,rank,longdistanceLawtonregrets,admirable!InNovember,IwasadmittedtotheFacultyoflaw,CollegeoflawandpoliticsinShanghai,butresignedfromthepostoffice,bidfarewelltothisshortandmemorablelife(J)thesiazhenboatburiedJapanesemorningofOctober,,siazhensicktoshunTangQiaocutters,fromNanxuntownjiaxingtoJapaneseboats,caughtdraggingbehindsmallboats,loadedwithmilitarygoodsSiazhentoolatetoescape,jumpedashoreJapancatchupwiththeboat,forcinghimtorowaboatMeanwhilecaughtthemigrantsvillageZhangShunSiazhenwassickforalongtime,villagetemplesCentralOfficeeveryday,carryouttheirdutiesCorrespondencerelatingtoeducationbytheChiefofthefirstsectionmarkedmydraftstatementWorkedafterafewmonths,I'vebeenburiedintheofficialprogram,veryrigidmonotonyofclericalcareer,flavourlessofAugustbetween,County,andSecretarytoIwithtoOfficemeeting,forGovernmentestablishedoneyearstoworkreported,fortimerush,priornotforfullprepared,hadtoinwaybyrankAnnMrdescribedoneyearstoaboutpeople,andfiscal,andbuilt,andtaught,andinsurancefiveaspectsimportantmatters,Iaccordinglydetailednarrativefinishingwritten,completedWujiangGovernmentestablishedoneyearstoofworkreportTurnbackandforthmonthShanRoad,apartfromtheSecretary,Mrrankfootdiseaseimmobility,bamboocarinsteadofwalkingoutside,squarefoot(exceptformyselfandguards),thewuxing,peace,SIan,Guangde,doorwayswing,ZhangZhutothedestinationwearingBuAtdiweitotheimportanttownsoftroopsisdifficulttoaccess,wehavetochangeangles,Shanruggedtrails,Sunandrainontheway,hardshipexceptions,ifthepatrioticandpassionsofthewar,thanthesuccessfulcompletionoftasksAnoldfrail,rank,longdistanceLawtonregrets,admirable!InNovember,IwasadmittedtotheFacultyoflaw,CollegeoflawandpoliticsinShanghai,butresignedfromthepostoffice,bidfarewelltothisshortandmemorablelife(J)thesiazhenboatburiedJapanesemorningofOctober,,siazhensicktoshunTangQiaocutters,fromNanxuntownjiaxingtoJapaneseboats,caughtdraggingbehindsmallboats,loadedwithmilitarygoodsSiazhentoolatetoescape,jumpedashoreJapancatchupwiththeboat,forcinghimtorowaboatMeanwhilecaughtthemigrantsvillageZhangShunSiazhenwassickforalongtime,villagetemplesCentralOfficeeveryday,carryouttheirdutiesCorrespondencerelatingtoeducationbytheChiefofthefirstsectionmarkedmydraftstatementWorkedafterafewmonths,I'vebeenburiedintheofficialprogram,veryrigidmonotonyofclericalcareer,flavourlessofAugustbetween,County,andSecretarytoIwithtoOfficemeeting,forGovernmentestablishedoneyearstoworkreported,fortimerush,priornotforfullprepared,hadtoinwaybyrankAnnMrdescribedoneyearstoaboutpeople,andfiscal,andbuilt,andtaught,andinsurancefiveaspectsimportantmatters,Iaccordinglydetailednarrativefinishingwritten,completedWujiangGovernmentestablishedoneyearstoofworkreportTurnbackandforthmonthShanRoad,apartfromtheSecretary,Mrrankfootdiseaseimmobility,bamboocarinsteadofwalkingoutside,squarefoot(exceptformyselfandguards),thewuxing,peace,SIan,Guangde,doorwayswing,ZhangZhutothedestinationwearingBuAtdiweitotheimportanttownsoftroopsisdifficulttoaccess,wehavetochangeangles,Shanruggedtrails,Sunandrainontheway,hardshipexceptions,ifthepatrioticandpassionsofthewar,thanthesuccessfulcompletionoftasksAnoldfrail,rank,longdistanceLawtonregrets,admirable!InNovember,IwasadmittedtotheFacultyoflaw,CollegeoflawandpoliticsinShanghai,butresignedfromthepostoffice,bidfarewelltothisshortandmemorablelife(J)thesiazhenboatburiedJapanesemorningofOctober,,siazhensicktoshunTangQiaocutters,fromNanxuntownjiaxingtoJapaneseboats,caughtdraggingbehindsmallboats,loadedwithmilitarygoodsSiazhent
