"Using the multiplication formula of 7 and 8 to find the quotient" Division II in the table PPT courseware

1. Create situations and introduce new knowledge

Introduction to the conversation: "June 1" Children's Day is coming soon. In order to celebrate their own festival, the students are carefully decorating the classroom under the guidance of the teacher. Let’s take a look at what they are preparing for!

question:

1. Looking carefully at the picture, what mathematical information did you find related to the preparation? Who can tell me?

2. Let’s look at this information together. Can you use the learning tools in your hands to show the results?

2. Learn new knowledge and explore independently

(1) With the help of intuition, independently explore and use the multiplication formulas of 7 and 8 to find quotients

Questions: 1. Does this picture have the same result as yours? Who can tell me how you put it?

2. Can you make equations when looking at this picture?

Summary: When we were calculating these two division equations just now, the first thing we looked at was the divisor. What the divisor is, just think of the formula. The formula "seven, eight, fifty-six" can calculate one multiplication equation and two division formulas. It seems that the multiplication formula is really important!

(2) Strengthen practice by using multiplication formulas to find quotients

question:

1. Let’s go back to this theme picture. We just saw these two pieces of information. Can anyone ask a math question based on these two pieces of information?

2. Will you solve this problem? Do the math.

49÷7＝7 Think: seven ( ) forty-nine

3. Why use division?

(3) Apply rules and practice formulas

Questions: 1. Who can quickly calculate their results using multiplication tables?

2. Which formula did you use for the first set of calculations? What about the second group? What about the third group?

3. Use formulas to consolidate practice

1. Do it.

7÷7＝ 32÷8＝ 48÷8＝ 56÷7＝

64÷8＝ 21÷7＝ 49÷7＝ 40÷8＝

2. Do the math.

5×＝35 6×＝42 49÷7＝

32÷8＝ 24÷8＝ 6× ＝42

4. Classwork

Homework: "Do it" on page 38, question 3. Exercise 8 on page 40, question 3.
