Teaching objectives:?
Let learning multiply is a simple form of adding several identical addends. Let students abstract the ability to solve several mathematical practical problems from simple practical problems and solve practical problems by multiplication. To cultivate students' interest in learning multiplication, the focus of teaching is to master the source of multiplication and understand its significance.
Teaching difficulties: identify the same addend and understand the meaning of two "factors". Teaching process: Revealing the fact that the subject animation star "Xiong Er" was officially introduced to count birds, and found it inconvenient to use the same addend. Then ask teacher Beibei for help and draw the source of multiplication.
The understanding of multiplication explains how multiplication changes from addition, and further explains the understanding of the names of various parts of multiplication. How to write addition as multiplication? How to write "the problem of adding a few" into the multiplication formula?
Practice consolidating the number of pictures and help Grandpa Wang count sheep (write multiplication by looking at pictures and solve simple multiplication problems to consolidate). In view of the students' inattention and poor understanding ability in this class, my micro-class design idea is to introduce story situations about anime stars to arouse students' interest and enthusiasm in this class.
In the whole micro-class, I slowed down and used this way to adapt to the understanding characteristics of smart students. In the whole process, I combine subtitles with pronunciation to fully mobilize students' "visual" and "auditory" senses. ?
