Opening remarks in primary school mathematics class

As the saying goes:? The hardest part is actually at the beginning? The success or failure of a class has a lot to do with the introduction of the opening. At the beginning of teaching, adding some riddles, jokes and stories appropriately can not only attract students' attention immediately, but also enliven the classroom atmosphere and improve the classroom teaching effect. Next, I sorted out the language at the beginning of primary school math class for you. Let's have a look.

The beginning of primary school mathematics classroom: story-based opening teaching? Division with remainder? When can the teacher tell the students one? Wukong divides peaches? Story:

One day, the Tang Priest brought 90 red and big peaches from Huaguoshan, and asked Wukong to count the number of monkeys. Then he said, you have 20, you have 4, and there is 10 left. Leave the rest to your pig! ? Soon, Bajie came back. He ate one, licked his mouth and asked Wukong for peaches. ? I won't. ? Wukong said angrily. I divided it like this, and the formula is here. ? Then Wukong threw a piece of paper to Bajie. Bajie looked at the formula, stepped forward, pointed to 1 in the vertical form and said to Wukong:? If you put this 1 in the tenth place, there is still 10 left, and you can eat nine by yourself. Brother monkey, brother monkey, your heart pig said and grabbed the rake. Seeing the bad situation, Wukong suddenly turned and disappeared.

The new lesson introduces stories, which are interesting and fresh, and are more easily accepted by students.

The beginning of primary school mathematics classroom: humorous beginning teaching? Integer multiplication? At first, the author asked the students to write two sums of 10 on the draft paper, and then wrote five sums of 10. Everybody write quickly. Finally, the author asked one student to write the sum of 100 10 on the blackboard, and the rest of the students kept looking at the number of edges:? One, two or three students are so busy that they are sweating, and several students are panting. When they counted to 66, the author asked. What if I ask you to write more than 1000? Then, the students who write should write happily, and the students who count should count with thirst. Do you want to find a simple algorithm? The student answered without thinking:? Want to! ? After saying his word, the author went on to say: OK. Now let's learn a new operation method-multiplication. ? In the case that such students are in urgent need of new methods, learning multiplication is just right.

Language at the beginning of primary school math class: the game at the beginning can quickly arouse students' curiosity, make students active at once and greatly improve students' attention. Teaching? Cyclic decimal? At the beginning of teaching, the author said to the students: Now let's make one together? High five? Games. ? Say that finish, me? One, two, three, two, three, clap your hands repeatedly, and so do the students. Just as everyone applauded neatly, the author stopped and eagerly asked: When everyone clapped just now, which three numbers were repeated? The student replied:? what's up One, two, three. Repeat. ? What can be summed up in one sentence? The student thought for a moment and then answered:? Available? Cycle? Generalization. ? In this way, we entered a new lesson.

Language at the beginning of primary school mathematics class: Does riddle begin with teaching? Understanding of 0? Sometimes, the teacher can solve such a riddle: like an egg is not an egg, it is round, not round; It is said that there is nothing but it, and the circles are connected in a string. Ask the students to guess a number. The riddle is simple and interesting, which instantly opens the students' brains, and they quickly guess and remember it? 0? .

The language of the beginning of primary school mathematics classroom: the beginning of suspense
