The speech of "Know What Time"
"Understanding a part" is the content of the fifth volume of the textbook of Jiangsu Education Publishing House. In the teaching process, considering the actual situation of students, (most students have been exposed to simple fractions in daily life, and the second class has a special class), I integrated this part of the teaching materials, put the content of a fraction in the teaching materials into the second class, and put the knowledge of a fraction in the second class into this class to teach, so that students' knowledge learning is more systematic and overall.
Teaching objective: 1. Know the score, read and write the score correctly, remember the name of the score and compare the scores.
2. Cultivate students' mathematical abilities in many aspects, such as hands-on practice, autonomous learning, active exploration and problem solving.
3. Experience the close relationship between mathematics and life, and experience the happiness of mathematical exploration and creation.
Teaching content: page 98- 100 of the textbook.
Analysis of students' situation: the initial understanding of scores is the expansion of the concept of logarithm on the basis of students' learning the concept of integer. Students are exposed to scores for the first time, but they have experienced them in life.
Preparation before class: multimedia courseware, rectangular, triangular and circular pieces of paper.
