Description

"Using the multiplication formula of 7, 8, 9 to find the quotient" Division in the table PPT download

Part One: Objectives of this Section

01 Experience the process of finding the quotient using the multiplication formulas of 7, 8, and 9.

02 Master the general method of finding quotients using multiplication tables.

03 Realize that using multiplication tables to find quotients is a tool to help people solve problems.

Use the multiplication formula of 789 to find the quotient PPT, the second part: review old knowledge

1. Fill in the form and tell which formula to use.

( ) × 3 = 24 4 × ( ) = 36

5×( )＝45 3×( )＝27

( ) × 6 = 48 ( ) × 5 = 40

2. Tell me which multiplication formula you used to figure out the number in ( ).

6÷( )=3 12÷( )=3

24÷（ ）＝4 （ ）÷3=5

（ ）÷5=5 18÷（ ）=6

Use the multiplication formula of 789 to find the quotient PPT, the third part: introducing new lessons

Look carefully at the picture and tell me what you see?

1. Can you explain the information in the picture in an organized way?

initial perception

1. Looking at this picture, can you make equations?

2. Which multiplication formula do you use for 7×8?

3. Which formula do you use for 56÷8 and 56÷7 respectively? How did you come up with this mantra?

Use the multiplication formula of 789 to find the quotient PPT, part 4: in-depth exploration

7×8=56 Formula: seven eight fifty six

56÷8=7 Think: ( ) eight fifty-six

56÷7=8 Think: seven ( ) fifty-six

Summary: When calculating these two division equations, the first thing to look at is 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 equations. It seems that the multiplication formula is really important!

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?

How many pills does each group get?

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

49÷7=7 (pieces)

3. Which formula do you use? How did you come up with this mantra?

Think: seven ( ) forty-nine

When calculating this question, we also look at the divisor first. The multiplication formula is whatever the divisor is. This is the method of using the multiplication formula to find the quotient.

Use the multiplication table of 789 to find the quotient PPT, Part 5: Consolidation Practice

1. Can you calculate their scores?

7×4＝ ​​8×2＝ 8×6＝

28÷4＝ 16÷2＝ 48÷6＝

28÷7＝ 16÷8＝ 48÷8＝

2. Do it.

7÷7＝ 32÷8＝ 48÷8＝ 56÷7＝

64÷8＝ 21÷7＝ 49÷7＝ 40÷8＝

3. Do the math.

4. Tug-of-war.

(1) How many books can each winning team member get on average?

48÷8＝6(this)

Summary: When we solve problems, we must connect relevant information and problems together, and carefully analyze the relationship between quantities, so that we can answer correctly.

(2) Can you ask and solve other mathematical problems?

Use the multiplication formula of 789 to find the quotient PPT, part six: summary of this section

01 It is relatively simple to use the multiplication formula to find the quotient. The multiplication table can not only calculate the product, but also the quotient.

02 When calculating division, first look at the divisor. Think of the multiplication formula as the divisor is. This is the method of using the multiplication formula to find the quotient.

03The same formula can help us calculate a multiplication equation and two division equations verbally.

Use the multiplication table of 789 to find the quotient PPT, Part 7: Assignment

1. Complete 4.1 online homework of finding the quotient using the multiplication tables of 7, 8, and 9.

2. Find problems around you that can be solved by using the multiplication formulas of 7, 8, and 9 to find the quotient and division, and talk about the meaning of division and the method of finding the quotient.
