Description
"Rewriting and Approximate Numbers of Numbers Over Hundreds of Hundreds" Understanding Bigger Numbers PPT Courseware
teaching objectives
1. Combined with real-life materials, experience the process of rewriting numbers above 100 million into numbers in units of "ten thousand" or "100 million" and experience the process of 100 million.
2. Be able to use the "rounding method" to rewrite a large number into an approximate number in units of "100 million" or "10,000".
3. Feel the practical significance of one hundred million, understand the wide application of number rewriting in real life, and develop number sense.
Review old knowledge
Rewrite the words on the horizontal line below into numbers in "ten thousand".
The Forbidden City in Beijing covers an area of 720,000 square meters.
The Old Summer Palace in Beijing covers an area of 3.46 million square meters.
Explore new knowledge
In 2011, my country's annual research and experimental development expenditures were 861 billion yuan, including 39.6 billion yuan in basic research expenditures.
How to rewrite the whole number into a number with "hundred million" as the unit?
How to rewrite the number with "hundred million" as the unit into the number with "10,000" or "one" as the unit?
(1) Rewrite it as a number with "pieces" as the unit.
861 billion = 8610 0000 0000
39.6 billion = 396 0000 0000
(2) Rewrite it as a number with "ten thousand" as the unit.
861 billion = 86.1 billion
39.6 billion = 39.6 billion
In conclusion
1. When rewriting a number with the unit of "hundred million" into a number with the unit of "ten thousand", remove the word "hundred million", add 4 zeros at the end of the number, and then write the word "ten thousand"; When rewriting it into a number in units of "units", remove the word "billion" and add 8 zeros at the end of the number.
2. Rewriting a number into units of "hundred million" is basically the same as rewriting a number into units of "ten thousand". They both use the "rounding" method. If the number obtained is an approximate number, use "≈" connection.
practice
1. Rewrite the numbers on the horizontal line below into approximate numbers in units of "100 million".
2. Rewrite the countries with a population of over 100 million in the world into numbers with “100 million” as the unit.
3. It costs about 500 yuan to help an out-of-school child return to school. If 1.3 billion people each save 1 yuan, approximately how many out-of-school children can be supported with this money?
