1.1.2比大小(教学设计)-2024-2025学年一年级上册数学人教版
教学重点是让学生掌握比较两个一位数大小的方法，以及会用符号表示大小关系。教学难点是让学生能够灵活运用比较方法，解决实际问题。
核心素养目标
本章节的教学旨在培养学生的数学核心素养，主要体现在以下几个方面：
1. 逻辑推理：通过比较两个一位数的大小，让学生学会运用逻辑推理的能力，理解大于、小于和等于的逻辑意义。
《数学之谜》：收集了许多数学谜题，如猜数字、逻辑推理等。学生可以通过解答这些谜题，挑战自己的思维极限，培养解决问题的能力。
2. 鼓励学生进行课后自主学习和探究：
(1) 探究其他比较大小的问题：让学生尝试解决比较两个两位数、三位数甚至更多位数的大小问题，引导学生发现比较大小的规律。
(2) 调查生活中的比较大小现象：让学生观察和收集生活中的比较大小实例，如购物时比较价格、比赛时比较成绩等，体会数学与生活的联系。
6. 问题解决：学生能够运用比较大小的知识，解决实际问题，提高问题解决能力。
学习者分析
1. 学生已经掌握的相关知识：学生在之前的学习中，已经掌握了数数、识数的基本能力，对一位数有了初步的认识。他们能够进行简单的数数运算，并能够识别和比较数字的大小。
2. 学生的学习兴趣、能力和学习风格：一年级的学生对图形和数字有天然的兴趣，他们喜欢通过观察、操作和实践活动来学习。在学习能力上，他们具备一定的观察能力和思考能力，但需要通过实际操作来加深对概念的理解。在学习风格上，他们更倾向于通过直观、动手的方式进行学习，对于抽象的概念和理论可能理解起来较为困难。

小学英文一年级知识点总结
小学英文一年级知识点总结English is an important subject for first graders as it lays the foundation for their language skills. In first grade, students learn the basics of English such as the alphabet, phonics, sight words, and simple sentence structure. Here is a comprehensive summary of the knowledge points covered in first grade English.1. AlphabetThe alphabet is usually one of the first things taught to first graders. They learn to recognize and write both uppercase and lowercase letters. Teachers use various games and activities to make learning the alphabet fun and engaging for students. By the end of first grade, students should be able to recite the alphabet and recognize all the letters.2. PhonicsPhonics is the method of teaching reading and writing by relating sounds to letters and groups of letters. First graders learn the sounds of the individual letters as well as how to blend them together to form words. Teachers use phonics-based activities, such as word families and rhyming words, to help students develop their phonetic skills.3. Sight WordsSight words are high-frequency words that students should recognize instantly by sight, rather than having to sound them out. First graders learn to recognize and spell basic sight words such as "the," "and," "is," "in," "it," "to," "you," and so on. These words are often taught through repetition and practice, and students are encouraged to use them in their own writing.4. ReadingFirst graders are introduced to simple books and stories to help them develop their reading skills. They learn to read both silently and aloud and are encouraged to use their phonics knowledge to sound out unfamiliar words. Teachers also guide students in developing comprehension skills by asking questions about the text and discussing the main ideas.5. WritingIn first grade, students begin to develop their writing skills by practicing handwriting and forming sentences. They learn to write their names, simple words, and short sentences. Teachers focus on proper letter formation, spacing, and punctuation. Students are also encouraged to use their imagination and creativity when writing.6. GrammarFirst graders are introduced to basic grammar concepts such as nouns, verbs, adjectives, and pronouns. They learn to identify and use these parts of speech in simple sentences.Teachers use games and activities to make learning grammar fun and interactive for students.7. SpellingSpelling is an important component of first grade English. Students learn to spell simple words phonetically and are encouraged to use their phonics skills to sound out unfamiliar words. Teachers also introduce spelling rules and patterns to help students become more proficient spellers.8. VocabularyFirst graders expand their vocabulary by learning new words through reading, writing, and conversations. Teachers introduce new words in context and encourage students to use them in their own speech and writing. Students also learn about synonyms and antonyms to help them understand the meaning of words.9. Speaking and ListeningSpeaking and listening skills are important for first graders to develop effective communication. They learn to speak clearly and confidently, and to listen attentively to others. Teachers provide opportunities for students to engage in group discussions, presentations, and role-playing activities to improve their speaking and listening skills.10. ComprehensionComprehension skills are essential for understanding written and spoken language. First graders learn to identify the main idea of a passage, make predictions, draw conclusions, and ask questions about the text. Teachers use a variety of reading materials and activities to help students develop their comprehension abilities.In conclusion, first grade English covers a wide range of knowledge points that are crucial for developing language skills. By mastering these fundamental concepts, students will be well-equipped to build upon their English language abilities in the future. Teachers play a vital role in guiding students through these knowledge points, making the learning process engaging and enjoyable. With a solid foundation in first grade English, students will be prepared to excel in their language skills as they progress through their educational journey.。
