Unit 1 第2课时 Discover & Develop（教学课件）英语人教大同版三年级下册（新教材）

该小学英语课件围绕“水果”主题，聚焦字母组合“a”（/æ/）和“m”（/m/）发音规则，水果词汇及数字11-20，核心句型（询问物品及数量）。通过“魔法果树角色扮演”等情境导入，从语音感知到词汇学习再到句型运用，以Lead-in-Presentation-Practice为支架，帮助学生逐步掌握知识。 其亮点在于情境任务驱动与语音主题融合，通过“魔法果树创作与介绍”小组任务，提升语言能力（运用句型连贯表达）和思维品质（语音分类、词汇迁移）。采用任务型学习，学生在实践中增强学习能力，教师可借助结构化流程和多样活动提高教学效果。
