How many posters draw the multiplication formula of 1 -6?
How many posters are there? This is the content of "Multiplication Formula of 6" in the first lesson of Unit 8, Unit 1, Grade 2 Mathematics in the compulsory education experimental textbook published by Beijing Normal University. Before learning this lesson, students have learned the multiplication formula of 2~5, and have a preliminary understanding of the significance of multiplication formula and how to compile multiplication formula. At the same time, this lesson is also the basic textbook for students to learn the multiplication formula of 7-9. By creating the problem situation of "how many pictures to post", students can actively explore the multiplication formula of 6 by using positive transfer on the basis of their existing knowledge, feel the joy of success in the learning process and enhance their self-confidence. Through three questions, the textbook allows students to fully discuss and communicate on the basis of independent exploration and cooperation, compile their own multiplication formulas of 6, and help students understand and remember these formulas through bitmap.
[Teaching objectives]
(1) Knowledge and skill objectives
Understand and remember the multiplication formula of 6, use the multiplication formula of 6 to calculate and solve simple practical problems.
(2) Process and method objectives:
By creating a story situation, I went through the process of compiling the multiplication formula of 6. With the help of bitmap, we can establish the connection between old and new knowledge, initially learn to learn new knowledge by analogy and experience the thinking method of exploring new knowledge from existing knowledge.
(3) Emotional and attitudinal goals:
Cultivate students' awareness of active exploration, cooperation and communication, feel the fun of exploration, and make students form a good habit of positive thinking.
[Teaching Emphasis and Difficulties]
Key points: explore independently in the activity, draw up the last four multiplication formulas of 6 with the help of existing knowledge and experience, and solve some simple practical problems with the multiplication formula of 6.
