"Using the multiplication formula of 7 and 8 to find the quotient" Division in the table PPT
Description
"Using the multiplication formula of 7 and 8 to find the quotient" Division in the table PPT
Part One: Learning Objectives
1. Let students experience the process of using the multiplication formulas of 7 and 8 to find quotients, master the general method of using multiplication formulas to find quotients, and develop the calculation skills of using multiplication formulas to find quotients.
2. Students will learn new knowledge through transfer.
3. Cultivate students' sense of cooperation, improve students' exploration ability, and feel the application value of mathematics.
[Key Points] Use the quotient methods you have mastered to discuss and summarize the general methods of calculating the quotient of the multiplication formulas of 7 and 8.
[Difficulty] Proficiently come up with appropriate formulas based on division equations.
Use the multiplication formula of 78 to find the quotient PPT, part 2 content: classroom analysis
"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!
Looking carefully at the picture, what mathematical information do you notice about the preparation? Who can tell me?
Let's look at this information together. Can you use the learning tools in your hands to show the results?
This is how I calculated it!
Do you know which formula is used for 7×8=56?
Formula: seven eight fifty six
How many flags are there in each row?
There are 56 small flags in total.
56÷8=7 Think: seven, eight, fifty-six
56÷7=8 Think: seven, eight, fifty-six
When we were calculating this division formula just now, the first thing we looked at was the divisor. What the divisor is, just think of the formula.
Use the multiplication table of 78 to find the quotient PPT, part three: classroom exercises
1 Can you calculate the following questions? Give it a try!
7×4＝ 8×2＝ 8×6＝
28÷4＝ 16÷2＝ 48÷6＝
28÷7＝ 16÷8＝ 48÷8＝
It seems that the same formula can help us calculate one multiplication and two division formulas verbally. The formula is really useful!
2Did you do it right?
Think about which formula you used?
Five Seven Thirty Five Six Seven Forty Two Seven Seven Forty Nine
four eight thirty two three eight twenty four eight eight sixty four
Use the multiplication formula to write one multiplication equation and two division equations.
For example: seven eight fifty six
Multiplication formula: 7×8=56
Division formula: 56÷7=8,56÷8=7 (use one of the first two numbers in the formula as the divisor, and the other is the quotient. According to this method, two division formulas can be written)
