After coming home from school in the afternoon, I used the calculator on my father's mobile phone to calculate the average height and weight of the children after work. Dad asked me, "which child is overweight and which child is short." I took a closer look: "Children A and B are heavy, and children C and D are short. They usually do more physical exercise. "
Dad's postscript: I designed this research activity to let Xiaoyu have more contact and communication with children, and I can ask the teacher for help if there are unfinished matters. I didn't expect her to get off to a bad start, but fortunately she didn't get discouraged. Come and have a close contact with the teacher. You said I remember. Later, I also learned that the child's height and weight were measured at the end of last year. Of course, most children forget. After returning home, Xiaoyu calculated the average with the calculator on my mobile phone, and she was very interested. She plays the leading role, I play the supporting role, and she calculates the average height and weight.
Xiaoyu took the initiative to ask the teacher for help; The teacher responded enthusiastically and solved Xiaoyu's problem. The success of this research activity has brought curiosity and confidence to Xiaoyu. Therefore, parents or teachers can design some topics in life or classroom teaching, so that children can investigate and obtain information from the media and daily life. For example: the number of gold medals and medals in Olympic countries; Date and year of birth of the classmate; People's height and weight; Daily temperature records and so on.
Through such practical activities, children realize that mathematics comes from life and eventually returns to life; Encourage children to explore independently and cultivate their practical ability and independence.
