Reflections on addition teaching within 5 1 1. Introduce the idea of highlighting separation and integration.
The meaning of addition comes from the idea of division and combination. At the beginning of teaching, based on the division and cooperation of several variants, students feel that they should use division and combination to solve new problems today.
Second, from arithmetic teaching.
When teaching examples, I guide students to see the process of change and explain the meaning of the picture through the change of picture and meaning. Three children are watering flowers in the campus, and two more come. At the same time, the third sentence appeared in the form of a question: How many children are there? Let students have a preliminary concept of conditions and problems, and understand that looking at pictures is to solve problems. Most students have been able to list the addition formula according to the figure: 3+2=5. This part is for students. In my experience, I always focus on the explanation of formula meaning, and the teaching of calculation focuses on arithmetic. I use the receptive learning method, and the students of "+"already know it. Instead, I let students feel that the meaning of "+"is combined through oral language and body language, combining the combination in image with the combination in meaning. Through the interpretation of the meanings of "3", "2" and "5" in the formula of "3+2=5", it shows that students can understand the meaning of numbers, say the meaning of the formula through the experience of division and combination, let students experience the image-number-symbol-language, and finally integrate the meaning of "3+"
Reflections on the teaching of addition within 5 2. The teaching of this course is based on students' learning the composition of numbers within 5 in the last class. In mathematics, addition is a commonly used calculation method, and it is also the basis of foundation, so learning this lesson well is very important for future mathematics learning. Although, in students' past life experience, the solution of some daily problems has made them have a more or less vague impression of addition, it is the first time for students to really understand addition and use it to solve problems. Therefore, the emphasis and difficulty of this lesson are: let students really understand the meaning of addition and use it to solve practical problems, and use the knowledge of the composition of numbers to do addition.
In this lesson, I pay attention to several aspects:
1, pay attention to let students learn mathematics in life, and strive to make the classroom reflect life, mathematics, autonomy, emotion and interest.
Some simple mathematical problems are extracted from students' life experience, which can stimulate students' initiative and enthusiasm in learning mathematics and enrich their understanding of addition.
2. Pay attention to the diversity of algorithms and the flexibility of thinking.
. When discussing the calculation method of "4+ 1=5", change the teacher to tell the students to listen, first think independently for the students, set up a stick and actively communicate with the deskmate. When the whole class communicates, in view of the differences in students' thinking and thinking angles, the calculation methods that come to mind must be diverse. In teaching, we should respect students' independent choice and let them choose their favorite calculation method.
3. Give full play to the charm of classroom teaching evaluation.
In teaching, teachers try to objectively analyze students' every move, and make reasonable comments on them in various ways, so that students can truly feel that teachers have been paying attention to them. At the same time, fully understand the current situation of students' learning and stimulate their enthusiasm for learning.
4. Pay attention to cultivate students' habit of speaking complete sentences and asking math questions.
For example, let the students observe the pictures, express the meaning completely, and test everyone with math problems.
Reflection on the teaching of addition within 5 3 Through the teaching of this class and the teacher's comments, I have realized more deeply that in the teaching of a class, we should learn to allocate time reasonably, highlight the important and difficult points, and distinguish between primary and secondary. We must pay attention to and cultivate students. Students are the subjects who actively seek knowledge and explore in the classroom, and teachers are the designers, organizers and guides of the classroom teaching process, serving the students. Therefore, in the future, we should not only focus on our own teaching ideas and complete our own teaching plan, but also consider the actual situation of students, and truly achieve "student-oriented" and "student-oriented development". The designed lesson plan must meet the development requirements of students, not let students adapt to the teacher's lesson plan.
Disadvantages:
1. Students' listening and answering habits need to be strengthened.
2. Students' interactive learning needs training. There are still some students who can't communicate their ideas (calculation methods) with their classmates well. It is necessary to cultivate students how to share their ideas with their deskmates, how to gain more knowledge through deskmate cooperation, and how to solve some difficult problems in learning, so that students can learn how to cooperate with others initially.
