Description
"Approximate Values of Quotient" Decimal Division PPT Courseware
How to find the approximate value of the quotient:
When calculating, divide by one more decimal place than the number of decimal places that need to be retained, and then use the "rounding method" to omit the mantissa.
What are the similarities and differences between finding the "approximate value of the quotient" and finding the "approximate value of the product"?
The same point: both use the "rounding method" to obtain approximate values, and both look at the last digit of the reserved digit.
The difference: to find the approximate value of the product, you must first calculate the exact value of the product, and then find the approximate number. To find the approximate value of the quotient, you do not need to find the exact value of the quotient, you only need to find the next digit to be retained.
1. Games:
Take the group as a unit, each person draws the most beautiful rectangle, measure the length and width of the drawn rectangle, and divide the width by the length to find the quotient. Whoever's quotient is closest to 0.618 will be the champion.
2. Check:
Do you know what "rounding" is? Please look up the information after class to understand it.
This courseware provides a comprehensive introduction to the approximate numbers of quotients through small games and exercises, which improves students' interest in learning and helps students better understand and remember the knowledge points of decimal division. It is a good classroom teaching courseware.
