Teaching objectives

1. According to the specific situation, explore and compile the multiplication formula of 7 independently, and feel the close connection between mathematics and life.

2. I will use the multiplication formula to calculate the multiplication in the table and solve some simple practical problems.

Teaching focus

Through inductive reasoning, the multiplication formula of 7 is compiled and mastered.

Teaching difficulties

Explore the multiplication formula of 7 from the existing knowledge exchange.

Preparation of teaching (equipment)

Wallcharts and tables.

Teaching and learning process

Teaching step

Teachers' activities and main concerns

Student activities

Design intent

1. How many days are there in a week?

Show me the scene map.

Look at the picture carefully: What are you trying to say? voice/air/express/vent one's views freely

What are you going to say? This open question opens the floodgates of students' thinking and enables them to ask questions in specific situations.

Second, the problem exploration

Students want to know so much. How many days are there in 2 weeks, 5 weeks and 9 weeks? Please count it yourself. Pay attention to the number of edges and fill in the results in the corresponding table.

Please tell me, how did you count it?

The teacher thinks that you can independently compile the multiplication formula of 7 according to the result of this form as before. When editing, pay attention to record the group activities, first say it yourself, fill it out yourself, and then communicate with the students in the group.

Students independently explore the multiplication formula of 7.

Let the students count and speak by themselves. The purpose is to let them explore, feel and experience the process of solving problems in a specific environment.

This link is intended to give full play to students' subjective initiative, and I believe students can learn and cultivate their reasoning ability.

Third, experience and think about what methods can quickly remember the multiplication formula of 7?

Recite the formula in the way you like. Let the students say and recite the formula by themselves, which will help them understand the meaning of the formula.

Fourth, practical application.
