Comments (can be nested in templates):

The first goal:

This teacher teaches a class in a certain grade. In the Teaching Reference, it is required to check the teaching objectives of this course before evaluating the course. If it is set inside, the teaching goal of a teacher's class will be very clear, and the key and difficult points will be highlighted. In the whole classroom, teaching design is also based on students' cognitive characteristics and learning situation, and the design is more reasonable on the premise of the implementation of elements.

Second import:

Classroom lead-in should be not only accurate, but also purposeful and targeted. Specifically, how to import, where to import, and effective import can quickly mobilize the enthusiasm of students. I think a teacher does this very well.

Third, the link design:

A teacher is good at digging up teaching materials and spends a lot of thoughts on teaching design, especially the design of so-and-so link makes people shine. Praise this link can not only fully mobilize the enthusiasm of students, but also cultivate children's good habits of active learning and research. Proper methods, teacher, not only make it easy to teach, but also make it easy for children to learn. I think this is a very timely design highlight.

Fourthly, interlanguage:

The teacher's language is concise, and it can be seen that every word and sentence are designed before class, and every question is clearly raised, so that students can understand the teacher's task in the shortest time and improve classroom efficiency. When instructing students to read the text aloud, the teacher quotes it in poetic language, and the children naturally follow it, entering the state in love, so that reading can really replace oral English and promote the road. The classroom is full of strong Chinese flavor.

Suggestion:

Understand the significance of decimal multiplication and master the calculation method of decimal multiplication; Strengthen estimation consciousness and cultivate estimation ability; Will find the approximate quantity of products, and can keep the approximate quantity of products according to the specific situation.

Difficulties: the determination of the decimal point position of the product; Keep the approximate quantity of products according to the specific situation.

Analysis of learning situation: From the age characteristics, fifth-grade students are active, curious and good at expressing. Grasping this characteristic of students, teachers can adopt vivid and diverse teaching methods and students' extensive and active learning methods to stimulate students' interest in learning, effectively cultivate students' thinking ability and promote students' personality development. Students have already known decimals, can add and subtract decimals, mastered the calculation method of multiplying two digits by two or three digits, and have the foundation for learning new knowledge in this unit. Teachers should attach importance to students' existing experience and make use of the familiar and commonly used decimal measurement units ("yuan, angle, minute" meter, decimeter, centimeter, etc.). ) Let students understand the relationship between decimal multiplication and integer multiplication, guide students to transfer the law and experience of integer multiplication to decimal multiplication through transformation, lay a solid foundation for students to learn the mixed operation of decimal multiplication and decimal multiplication, addition, multiplication and subtraction, and let students learn to discover the law.
