Elementary school students' mathematics hand-copied newspaper materials:

Students can realize that mathematics exists in real life and is widely used in the real world, so that they can appreciate the value of mathematics. "Learning mathematics is about better serving life. Application and life, apply what you have learned.

The Origin of Mathematical Symbols.

In addition to memorization, mathematics also needs a set of mathematical symbols to represent the interrelationship between numbers and numbers, and between numbers and shapes. Mathematical symbols were invented and used later than numbers, but in much greater numbers. There are more than 200 commonly used now, and there are no less than 20 kinds in junior high school math books.

They all have an interesting experience.

For example, there used to be several kinds of plus signs, and now they are commonly used"+"Number.

The number is from Latin"et"("with"meaning). In the sixteenth century, the Italian scientist Tataria used Italian"più"The first letter of (the meaning of plus) means to add, and the grass is"μ"In the end, it all became"+"Number.

The number is from Latin"minus"("minus"meaning), abbreviated m, and then omit the letters, and it becomes"-"Finish.

In the fifteenth century, the German mathematician Weidmei formalized:"+"Used as a plus sign,"-"Used as a minus sign.

There used to be more than a dozen kinds of multiplier signs, and now there are two kinds of common ones. One is"×", which was first proposed by the English mathematician Autter in 1631; One is"· "It was first pioneered by the British mathematician Heriott. The German mathematician Leibniz argued:

"The number is like the Latin alphabet"x", to be opposed, but in favor of"· "Number. He himself proposed to use it"п"Indicates multiplication. But this notation is now being applied to set theory.

In primary school mathematics learning, it is indispensable to copy the mathematics hand-copied newspaper, because this can increase students' interest in mathematics and improve students' ability to actively learn mathematics.

The story of mathematician Chen Jingrun:

The conversion relationship of time, for example, one minute and sixty seconds, is mainly a unit conversion, or is it just a representation of hours, minutes, and seconds, and you can draw a dial.

Time is like an arrow that goes out and never comes back. Let Xuezhi.com introduce you to the hand-copied newspaper of mathematics and cherish time, I hope it can be of some help to you!

Since there is no miracle "all at once", break your own record, keep refreshing the number of times you have fought against suffering, and fight to the end as long as you still have a breath. In fact, later you will find that it is precisely because of your own little persistence that you have achieved yourself, and the situation will be different.

<>1) There are 12 months in a year.

There are 31 days of the month of the Great Moon, and there are 7 major months of the year, which are January, March, May, July, August, October, and December.

There are 30 days of the month of the month, and there are 4 months of the year, which are April, June, September, and November.

2) February is neither a big month nor a small month.

3) There are two ways we can record the size of the month:

One is fist memory. (Using the concave and convex joints of the fist, practice while pointing to the fist, see the book P18 diagram: January is big, February is neither a big month nor a small month, March is big, April is small, May is big, June is small, July is big, August is big, September is small, October is big, November is small, December is big).

The second is the formula method: seven days before the single month, eight after the two months.

4) July and August, December and January are all consecutive big months.

If the emphasis is placed on the same year, then only July and August are consecutive big months.

The large consecutive months add up to 62 days.

A big month and a small month together are 61 days.

5) There are 7 days in a week, with a minimum of 4 Sundays and a maximum of 5 Sundays per month.

6) The date is the same for every 7 days plus the day of the week.

For example, if June 1 is a Wednesday, then June 8 is still a Wednesday, and June 15 is also a Wednesday.

7) A year with only 28 days in February is a normal year, and there are 365 days in a normal year.

A leap year with 29 days in February is a leap year, and a leap year has 366 days throughout the year.

There are 3 common years and 1 leap year every 4 years.

8) Usually Gregorian years that are multiples of 4 (divided by 4 and have no remainder) are leap years.

But a Gregorian calendar year is a whole hundred (with two zeros at the end), and it must be a multiple of 400 (divided by 400 without a remainder) to be a leap year.

Practice which years of the year are common years and which years are leap years.

9) There are four quarters in a year.

The first quarter is January, February, and March, and the first quarter of a normal year has 90 days.

The first quarter of a leap year has 91 days, columnar.

The second quarter is April, May, and June, and each year is fixed with days, columns.

The third quarter is the month, the month, the month, and the year is fixed as the day, column.

The fourth quarter is month, month, month, and the year is fixed as days, columnar.

10) There are 7 days in a week, and there are 365 days in a normal year with a week and 0 days, column.

There are 366 days in a leap year, and there are weeks and days, columnar.

1) The hour and minute hands coincide on the hour, so 24 hours a day, they coincide 24 times. , at a 90-degree angle twice per hour, for a total of 48 times.

2) The minute hand goes one turn, and the hour hand goes 1 12 times.

From 1 o'clock, the minute hand coincides with the hour hand when it makes an X turn.

x = 1 12 + x 12 (the distance traveled by the minute hand = the position of the hour hand at 1 o'clock + the distance traveled).

11/12 x = 1/12

x = 1/11

The minute hand goes 1 11 turns, which is 60 11 minutes.

1:60 The first time it coincided at 11 minutes.

<>Year, Month and Day" knowledge points related to "year": 1. One year = 12 months, half a year = 6 months, ordinary year = 365 days, leap year = 366 days 2, judging common years and leap years: method: one leap in four years, no leap in one hundred years, and leap in four hundred years.

For example: 1968 - leap year, 1954 - common year, 1900 - common year, 2000 - leap year. Judgment method:

The last digit of the year is an odd number, and it must be an ordinary year, such as: Hall macro ......There are two simpler ways to see if the last digit of the year is an even number, such as: (1) See if the last two digits are divisible by 4, such as:

1928, the last two digits are 28 4 = 7 so it is a leap year; Another example: 1918, the last two digits are 18 4 = 4 ......2 So it was a common year.

2) Remember that the special year 2000 is a leap year. Use the year to be judged to find the difference, for example: 1996, 2000-1996 = 4, 4 is divisible by 4 (is a multiple of 4), so it is a leap year; Another example:

In 2016, 2016-2000=16, 16 is divisible by 4 (is a multiple of 4), so it is a leap year.

3. Calculate the year: Method: last year - initial year = anniversary For example:

October 1, 2011 marks the 62nd anniversary of the founding of the People's Republic of China. 2011-1949=62 (anniversary) For example: June 8, 2012 is Xiao Ming's 9th birthday, what year was he born?

2012-9=2004 (year) Knowledge related to "month": 1. Big month = 31 daysThere are 7 big months and small months = 30 days in the yearThere are 4 small months and half a month = 15 daysFebruary = 28 days in a leap year February = 29 days 2. Methods for judging big months, small months, and leap months (February): (1) Fist memory method.
