On Wednesday afternoon, the Rainbow Flower Math Fairy Tale class arrived as scheduled. I listened to the lesson "Preliminary Understanding of Multiplication" shared by Li Yanling for the children in Grade One and Grade Two. Teacher Li carefully designed and explained in detail, so that the children were full of harvest. Every link is clear and natural, step by step, so that children can use their hands and brains. First, introduce fairy tales into the new curriculum to stimulate children's interest in learning mathematics; Second, Oughtred leads to multiplication, while the iron is hot, so that children can feel the magic of mathematics; Third, summarize the characteristics of addition formula and list multiplication formula, and it comes naturally; Fourth, challenge yourself, look at pictures and draw formulas to consolidate the knowledge points you have learned; Fifth, the application of multiplication in life makes children feel the role of mathematical knowledge in life. Mathematical knowledge comes from life and is applied to life; Sixth: summarize the key points of this lesson and let the children know what you have learned; Seventh: homework.

Mother Pig took Brother Pig, Brother Pig and Porky Pig to pick apples in the orchard. But who picked more apples? Clever Porky Pig came up with an idea: use the addition calculation we have learned.

8+8+8+8=32

5+5+5+5+5=25

3+3+3+3+3+3= 18

At this moment, the children's eyes widened, reflecting the light of wisdom, simple! I can do it too! But Miss Li raised a new question. If there are 100 cases, then 200 cases ... 1000 cases, is it inconvenient to add? A child shouted, "This is too much trouble." Some children tugged at their chins with their hands, lost in thought ... at the moment, Mr. Li was striking while the iron was hot. If you are a child who is diligent in thinking and loves learning, you will find a great person-it should be red.

What characteristics do you find from the above addition formula? Yang Lie raised his hand so high that Peng Zishuo, Yang Wenting and Chi Liang raised their hands, while Li Junqi and Guo Xiang dared not raise their hands. Because there are few schools in class, teachers give them more opportunities to sign up for classes. Yang Lie's answer was well received by the teacher, and his eyes narrowed with laughter.

After the children learned to perform several simple operations on the same addend sum by multiplication, Miss Li came up with another trick:

The children are gearing up, looking at pictures, drawing formulas, putting down rulers and picking up pencils. Smart Yang Wenting is loved by everyone for her earnest appearance, while sensible Chi Liang is afraid of making mistakes. She checked over and over again, and Peng Zishuo, who claimed to be a princess, was also seriously writing and drawing. The lovely Sophia Kao classmate is slower than a snail and makes you sweat. But what about her? Brother Xiang's handwriting is so messy. Han provided is just looking around. ...

Unconsciously, the bell rang, and the children who love learning and thinking are still busy. ...
