三年级下册英语第二单元评课稿范文全文共3篇示例，供读者参考篇1Unit 2 Lesson EvaluationThis unit was all about "My Day" and learning vocabulary and phrases related to daily routines and activities. I thought it was a really fun and useful unit!First, we started by learning some key vocabulary words like "wake up", "brush my teeth", "get dressed", "have breakfast" and more. The textbook had really colorful pictures that helped me remember what each word meant. Our teacher also brought in props like a toothbrush, bowl, and pajamas which made it even more entertaining to learn the new words.We practiced the vocabulary through lots of different activities like flashcard games, singing songs, and acting out the morning routines. I especially loved the "What comes next?" game where we had to put the daily actions in the right order. It really helped cement the vocabulary in my mind.After we had learned the basic words, we moved on to talking about times of day and describing our schedules. Thiswas a bit trickier for me because telling time is still something I'm working on. But the textbook had lots of examples and practice activities focused just on telling time using phrases like "at 7o'clock", "in the morning/afternoon/evening", etc.By the end of that section, I felt pretty confident using simple phrases like "I wake up at 7 o'clock" or "I have dinner at 6 PM." We even did a fun project where we wrote out and illustrated our own daily schedules to share with the class.The part I struggled with most in this unit was using frequency adverbs like "always", "usually", "sometimes" and "never." There were so many of them to remember and learn how to use properly. The textbook had some fill-in-the-blank exercises but I think I needed even more practice with those.However, my favorite part of the whole unit was when we learned how to ask and answer questions about daily routines using "What time do you..." and "When do you..." I loved getting to interview my classmates and find out how their days differed from mine. It was really interesting to learn about the different schedules and routines we all have.We wrapped up the unit by doing roleplays in small groups where we pretended to interview each other about our daily livesusing all the phrases and vocabulary we had learned. I think doing that really solidified everything for me.Overall, I feel like I know so much more vocabulary about daily routines now and can use basic phrases to describe my own schedule pretty well. Asking questions is still a little hard for me, but I'm slowly improving. I'd give this unit an 8 out of 10 - it was very practical and useful, but some of the grammar points were pretty challenging for a third grader. With more time and practice though, I know I'll have those vocabulary words and phrases down pat!篇2Unit 2 ReviewHi everyone! I'm going to tell you all about Unit 2 in our English book. This unit was called "My Neighborhood" and it taught us lots of cool things about places around where we live.The first lesson introduced words for different buildings and places we might see in our neighborhood. Some of the new vocabulary words were "park", "library", "supermarket", "hospital", "restaurant", and "movie theater". I thought the pictures helped me learn the words really well. My favorite activity was when we had to draw our own neighborhood mapand label all the places. I drew my house, the school, the playground, and the ice cream shop!Next we learned about prepositions like "next to", "across from", "between", and "on the corner of". These helped us describe where things are located. I practiced by closing my eyes and listening to my teacher say sentences like "The library is across from the park." Then I had to point to those places on the neighborhood map. It was hard at first but I got better!One reading was about a boy named Jack who was going to meet his friends at the movies. He walked there and the story used a lot of those preposition words to show his path, like "He turned left at the corner of Oak Street and Main Street." I could really picture where he was going. At the end of the story there were comprehension questions and I loved raising my hand to answer those.Another lesson focused on asking and giving directions. We learned question starters like "How do I get to..." and "Which way is..." We also learned to use instructional phrases like "Go straight", "Turn right", and "Walk two blocks." My best friend Sam and I pretended one of us was a tourist and the other had to tell them how to get somewhere in our neighborhood. It was really fun!One of my favorite activities was when we all got into small groups and did a neighborhood scavenger hunt. The teacher gave each group a list of things to find around the school like "something green", "a circular shape", and "a road sign." We had to walk around looking carefully and checking things off our list. My group found a green leaf, a stop sign, and even a manhole cover!We also read a funny story called "The Lost Puppy" about a little dog who got loose and wandered all over the neighborhood. The story was full of descriptive words for buildings and places, so you could imagine where the puppy was at each part. There was an illustration on each page too. At the end, the puppy ended up back at his house across from the park. Phew!For the unit project, we had to make a 3D model of our neighborhood out of craft supplies like boxes, clay, popsicle sticks, and construction paper. I made my house, the corner store, and the swingsets at the park. It was really neat to see everyone's creative neighborhood models at the end. Some people even included roads, trees, and little pedestrians!Overall, I think Unit 2 was awesome and I learned so many good English words and skills for describing my neighborhood.Knowing prepositions and directions will definitely help me if I ever get lost or need to explain to someone how to get somewhere. The stories and activities made it way more fun than just memorizing vocab words from a list.I'm already excited for the next unit, which is called "Delicious Foods" from what I've seen in the table of contents. I can't wait to learn all about different foods, maybe some crazy ingredients, and how to order at a restaurant. English class is my favorite!篇3Unit 2 Lesson Plan EvaluationThis unit was all about foods, meals, and healthy eating habits. I thought it was a really fun and engaging unit! We learned lots of new vocabulary words for different foods, how to talk about foods we like and dislike, and how to describe our eating routines. The lessons had a good mix of activities to practice speaking, listening, reading, and writing.VocabularyWe started by learning the words for different categories of foods like fruits, vegetables, grains, proteins, and dairy. I already knew words like "apple", "carrot", and "milk" but I learned lots ofnew ones too. Some of the trickier words for me were "broccoli", "lentils", and "yogurt". We played fun games like Word Wizard and Food Pyramid to practice identifying and categorizing the new words.Then we moved on to words for meals and dishes, like "breakfast", "lunch", "dinner", "sandwich", "soup", and "salad". I loved the picture flashcards we used to learn and review these words. We also learned adjectives to describe tastes, like "sweet", "sour", "spicy", and "bitter". Finally, we learned phrase chunks to express food preferences like "I like...", "I don't like...", "My favorite food is...", and "I'm allergic to...".Listening & SpeakingOne of my favorite activities was when we did surveys, asking and answering questions about our favorite foods and eating habits. We had to listen carefully to our partners' responses and repeat back what we heard. It was fun to find out how many people liked pizza best or preferred breakfast over other meals.We also did lots of fun role-plays, like ordering food at a restaurant or having a conversation about healthy vs unhealthy snacks. The teacher gave us realistic prompts and dialoguemodels to follow. I got to practice my speaking skills while also using the new vocabulary from the unit.For listening practice, we watched videos and did information gap activities. One video was about kids making their own healthy lunchboxes. We had to check off the ingredients they used from a list. Another time, we worked in groups to put picture cards in the right order to match a story we heard about a family's morning routine.Reading & WritingWe read simple stories, articles, and menus related to the unit topic. The readings helped reinforce the vocabulary and grammar from the unit, like using "some" and "any" with food words. The stories were engaging and had funny illustrations, like one about a boy who only wanted to eat pizza for every meal.For writing, we filled out graphic organizers to plan and then wrote paragraphs describing our favorite meal or our typical eating routine. We also created fun "dream menus" for an imaginary restaurant and had to include descriptions of the dishes. My menu was all desserts and sweets! We worked hard on using transition words and conjunctions to connect our sentences.Games & ActivitiesThis unit had so many interactive games and hands-on activities to make it more engaging. We played food vocabulary Bingo and did dictionary races to review the words. In one funny task, we had to categorize pictures of different foods as "Healthy" or "Unhealthy" snacks and then explain our reasoning.We also did a project where we created posters advertising a "new" healthy snack or dish. We had to include persuasive language and descriptive words to make it sound appealing. My group's snack was "Rainbowlicious Fruit Kebabs".Another time, we got into small groups and each group was assigned a different meal - breakfast, lunch, dinner, or a snack. We had to work together to plan a balanced menu with healthy options from all the different food groups. It was a good way to apply what we learned about nutrition.Overall ThoughtsI really enjoyed this unit and learned so much practical vocabulary and expressions related to food, meals, and eating habits. The lessons had a nice mixture of activities to work on all four skills - speaking, listening, reading, and writing. Everything was very hands-on, interactive, and engaging.Some units can feel repetitive if we just do boring worksheets or drills over and over. But this one had us up and moving, working in groups, creating projects, and using the language in communicative scenarios. The role-plays, games, videos, and other multimedia resources made it fun and helped bring the language to life.The lessons were well-structured too. We started by building the core vocabulary, then learned phrases and chunks to have basic conversations. The later lessons introduced grammar points like count/non-count nouns and quantifiers. And we always circled back to review and recycle vocabulary from previous lessons.My only critique is that I wish we could have done even more interactive and project-based tasks. Maybe we could have held a "Healthy Snack Tasting Fair" at the end to try each group's snack creations. Or done some research and presentations on foods from different cultures around the world. But overall, I felt very engaged throughout this unit and came away with a lot of new, practical language skills!。

人教版六年级数学下册第二单元解决问题评课1. 用数学的语言解释折扣。

对于折扣问题,学生在现实购物中虽然已经有所认识,但是具体的内涵还不是很清楚。

于是我就设计了商品促销的现实情境,让学生在情境中感受和理解打折。

解决本节课的难点部分,让学生知道打折就是现价是原价的百分之几,这里的百分之几表示的是现价,而不是便宜的部分。

在理解的基础上,学生再去探索解题方法就水到渠成了。

2. 分析题意,用数学的知识探究生活中的折扣问题。

这一过程中,我选择的所有折扣问题,都是学生实际生活中经常遇到的,除了学生经常光顾的文具店有折扣问题,还有我们经常吃的麦当劳等的优惠券,也蕴含着折扣问题。

这样学生对于要解决的问题就很感兴趣,积极性也就更高了,更重要的是培养他们用数学的眼光去看待生活中的问题,感受数学的力量。

2 成数教学中注重紧密联系学生的生活实际,利用学生在日常生活中触手可及的新闻消息等,创设教学氛围,让学生既体会到数学源于生活,又认识到所学数学可应用于生活。

同时,教师引导学生大胆地猜测,积极地讨论,主动地探索,勇敢地尝试。

将教学活动建立在学生已有的知识经验基础之上,所以课堂气氛活跃,学生学得起劲,学得主动。

但在成数、折扣应用题的教学上,个别学习困难的学生还是有理解较慢的情况。

由此看来,应在讲授新课前,适当增加对百分数应用题的复习。

3 税率1. 课程一开始,让学生充分体会祖国日新月异的变化,在激发学生爱国情怀的同时,理解我们现在生活中税收的重要性,为本课的学习做了良好的铺垫。

在启发引导出算法的基础上,让学生尝试自己解决问题。

这是一个生活化、应用化非常强的习题,它的算法是约定俗成的,所以我认为应先探索方法。

有了正确的方法后,再让学生应用计算,减少了练习的盲目性和对接受正确方法的负面影响,有利于正确算法的巩固。

2. 继续加强“如何分析问题”的训练,做到“先思考,再列式”,养成良好的审题习惯。

另外,在练习时要求学生做完题后“再回头想一想”,养成检查的习惯,这样一些错误就能及时地发现。

人教版六年级上册第二单元分数乘法评课稿教学目标1、通过操作活动使学生理解分数乘分数的算理，从而掌握计算方法。

2、发展学生的观察推理能力。

教学准备1、多媒体课件。

2、每个学生准备一张长15cm、宽10cm的长方形纸。

重点难点：分数乘分数的计算方法。

教学过程一、创设情境引入新课（教师谈话，以学校粉刷教室或家庭装修新房等学生身边的实例引入）出示粉刷墙壁的画面，给出条件：每小时粉刷这面墙的1/5。

师：能提出什么问题？学生提问题，教师板书。

以分数乘整数的问题作研究内容，如“2小时可以粉刷这面墙的几分之几？”师：怎样列式？（板书1/5×2）师：列式的依据是什么？为什么用乘法？（工作效率×工作时间=工作总量）让学生计算，并说说怎样计算。

师：我们解决了2小时粉刷多少的问题，那么1/4小时可以粉刷这面墙的几分之几？（出示问题）怎样列式？依据是什么？学生讨论汇报。

（根据“2小时可以粉刷这面墙的几分之几”的列式类推出，或根据工作效率×工作时间=工作总量，可以列出1/5×1/4）。

板书算式。

师：（结合板书讲解）我们已经知道求2小时粉刷这面墙的几分之几，就是求2个1/5是多少。

求1/4小时粉刷这面墙的几分之几，就是求1/5的1/4是多少。

那么1/5×1/4如何计算呢？这就是我们今天学习的内容。

板书课题：分数乘分数二、操作探究计算算理师：下面我们来探讨分数乘分数怎样计算。

我们每人准备了一张纸，把它看作这面墙，先在纸上涂出1小时粉刷的面积，应该涂出这张纸的几分之几？学生操作。

学生交流是怎样涂的？（用折或量、分的方法把纸平均分成5份，涂出其中的1份，如下图）师：我们已经知道，求1/4小时粉刷这面墙的几分之几，就是求1/5的1/4是多少。

再涂出1/5的1/4，小组讨论一下，应该怎样涂？小组汇报（把涂出的1/5部分再平均分成4份，涂出其中的1份）。

学生自己涂色。

师：从涂色的结果看，1/5的1/4占这张纸的几分之几？1/20师：我们可以得到1/5×1/4=1/20。
