1, multi-digit reading of French songs should start from the high position, and which one is read several times.
If there is a zero at the end of each level, you don't have to keep it in mind.
If the other numbers are zero in a row, just read one.
Read 10,000 at the end of 10,000 and 100 million at the end of 100 million.
2, multi-digit writing songs
Write a few numbers from it, as many as you want.
Whoever doesn't have a unit, remember to use 0 to occupy the place.
3, multi-digit size comparison songs
The number of digits is different from the size, with more digits and less digits.
The number of digits is the same, but there are fewer digits and more digits.
4. Operate the sequence of songs
Playing bamboo boards rang all over the sky. Listen to me, students
Today we will talk about four operations instead of other tables.
Clear order is the key to the calculation of mixed test questions.
At the same level, from left to right,
There are two levels of operations, first multiplication and division, then addition and subtraction.
What should I do if I encounter parentheses? Parentheses take precedence.
After parentheses, the order cannot be out of order.
Check every step, and be happy when you are right.

Knowledge points of intersection and verticality: 1, concepts of intersection and verticality. When two straight lines intersect at right angles, they are perpendicular to each other. (perpendicular to each other: straight line OA is perpendicular to straight line OB, and straight line OB is perpendicular to straight line OA) The intersection of these two straight lines is called vertical foot. The fact that two straight lines are perpendicular to each other illustrates the positional relationship between the two straight lines: they must intersect and intersect at right angles. )
2. Draw a vertical line:
(1) The method of drawing a vertical line through a point on a straight line.
Overlap one right-angle side of the triangle ruler with this straight line, the vertex of the right angle is the vertical foot, and draw a straight line along the other right-angle side, which is the perpendicular of the previous straight line. Pay attention to make the right-angle vertex of the triangular ruler coincide with the given point.
(2) the method of drawing vertical lines outside the straight line.
Overlap one right-angle side of the triangle ruler with this straight line, let the other right-angle side of the triangle ruler pass through this known point, and draw a straight line along the other right-angle side of the triangle ruler, which is the perpendicular of the previous straight line. Note that when drawing, you usually hold a triangular ruler in your left hand and draw lines in your right hand. Draw a vertical line through a point outside the line, and the other right-angled side of the triangular ruler must pass through a given point.

1, the meaning unit of a fraction "1" is divided into several parts on average, and the number representing such one or several parts is called a fraction.
In the score, the middle horizontal line is called the dividing line; The number below the fractional line is called the denominator, indicating how many copies the unit "1" is divided into on average; The number below the fractional line is called the numerator, indicating how many copies there are.
Divide the unit "1" into several parts on average, and the number representing one part is called fractional unit.
2. Classification of scores
True fraction: The fraction with numerator less than denominator is called true fraction. The true score is less than 1.
False fraction: Fractions with numerator greater than denominator or numerator equal to denominator are called false fractions. False score is greater than or equal to 1.
With fraction: False fraction can be written as a number consisting of integer and true fraction, which is usually called with fraction.
3. Subtraction and total score
Changing a fraction into a fraction equal to it, but with smaller numerator and denominator, is called divisor.
The denominator of a molecule is a fraction of a prime number, which is called simplest fraction.
Dividing the scores of different denominators by the scores of the same denominator equals the original score, which is called the total score.

One morning, after breakfast, the little monkey skipped to the home of his good friend, the little white rabbit, thinking that he could play his own game with the little white rabbit, and he was happier. Came to the home of the little white rabbit and found the little white rabbit standing in front of the water tank with a sad face. Seeing the little monkey coming, I shouted, "Brother Monkey, you are here." Then the little white rabbit said with a bitter face, "the water was cut off this week." I went to another town the day before yesterday and bought a barrel of 2 1L pure water. I want to drink 1/7 every day I sweated with my friends yesterday and drank 6/7 more than usual. Look at the water in this tank. Can you help me calculate enough? "
"Yes, no problem." The little monkey drew a line drawing on the ground and said, "This represents 2 1L water. Think of it as the unit'1'and divide it into 7 parts on average. You drink one such drink every day. " The little monkey pointed to another line segment and said, "This is 2 1L water 1/7. Take it as the unit'1'and divide it into 7 parts on average. You had six more drinks yesterday. 2 1L water 1/7 is 2 1× 1/7 = 3 liters. You drank 3×6/7= 18/7 liters too much yesterday. If you count today, you still have 2 1-3× 3-6558. White rabbit, is this water enough for you to drink for four days? "
"Oh, I'm not sure," said the little white rabbit absently. "Anyway, let's get ready first." "well! It's always good to plan ahead. " Say that finish, then catch up with the little white rabbit and go to buy water with him.

Today, I finished my homework early in the morning. My mother saw it and came up to me and said, "Zini, play a game with you!" " ""good! " I readily agreed. Mother brought a round cardboard and fixed a rotatable pointer in the center of the cardboard with a nail. The cardboard is divided into 24 grids on average, and the number 1-24 is written in each grid. "Mom, what are the rules of the game? Say it! "I said impatiently that the rules of the game are simple, that is, when the pointer turns to an odd or even cell, the next number must be added. If it adds up to an odd number, I win; If the total is even, you win. "Mom said with a smile.
I saw that the rules of the game were very simple. I played for more than a dozen times in a row, but I couldn't beat my mother every time. My mother smiled. "Why is it always singular?" I asked my mother puzzled. Mom said, "Think for yourself!" So, I racked my brains to think, and finally reminded me of the formula that the teacher once said: odd+even = odd. Now I can see that if the pointer points to the odd number, then the next number must be even; If the pointer points to an even grid, then the next number added is odd, so no matter where the pointer points, the number added is odd. Mom won with this rule.
In the world of mathematics, there are many wonderful laws. As long as we learn math well and make good use of it, it is everywhere!
