First, let students learn mathematics in vivid and concrete situations.

The whole design introduces fairy tales, creates situations that students are interested in, vividly and naturally, quickly attracts students' attention, well mobilizes students' learning enthusiasm, stimulates students' desire to participate, and enables students to complete their learning tasks easily and happily.

Second, pay attention to guiding students to master learning methods.

In the teaching process, teachers guide students to pay attention to the organic connection between multiplication formula and multiplication meaning when compiling formulas, understand the structure of formulas and understand the compilation methods of formulas. Help them truly understand the meaning of multiplication formula in independent exploration and cooperation and exchange, and at the same time accumulate certain mathematical ideas and methods, so as to lay the foundation for future mathematics learning.

Third, consolidation exercises should be timely and effective.

After learning an example, arrange exercises to consolidate new knowledge in time, which is conducive to students' internalization of new knowledge. After teaching the first and second examples, the assigned exercise is "think about doing 1 problem", which changes from an intuitive stick to a multiplication formula, and finally writes it as a multiplication formula. It makes students go through the process from image to abstraction, and helps them understand the meaning of multiplication formula. After teaching the third example, I arranged "thinking and doing the second question" to make students realize once again that one formula can correctly calculate two related multiplication formulas. Enhance students' ability to flexibly apply multiplication formulas.
