Unit 1 第4课时 B Let's talk ＆ Look and say（讲解课件）-【优翼·学练优】2025-2026学年新教材四年级英语下册同步备课（人教版PEP）

该小学英语课件围绕“课堂规则与值日任务”展开，核心知识点包括句型“I can...”及blackboard、tidy等词汇。通过“Watch and guess”视频（理解“on duty”）和“Look and say”图片导入，从日常规则过渡到值日行动，搭建连贯的学习支架。 其亮点在于融合语言能力、思维品质与学习能力培养。通过Role play对话表演、小组“Make a plan”讨论（用“I can...”制定值日计划）及评价表，提升语言表达与合作思维。包含歌曲、视频、听力活动，学生能在实践中运用语言，教师可借助结构化活动与评价工具提高教学效果。
