What are the key points of 6th grade mathematics Chinese review, and what are the key knowledge of 6

Grade 6 Mathematics Focus:1. The calculation rules of fraction multiplication:

1. Multiplication of fractions and integers: the product of multiplication of numerators and integers is the numerator, and the denominator remains unchanged. (Integer and denominator approximation).

2. Multiply fractions and fractions: use the product of numerators multiplied as the numerator, and the product of the denominator multiplied as the denominator.

3. In order to make the calculation simple, those that can be divided should be divided first, and then calculated.

2. Rule: (when comparing the size in multiplication) pure pants.

1. A number (except 0) multiplied by a number greater than 1, the product is greater than this number.

2. A number (except 0) multiplied by a number less than 1 (except 0), and the product is less than this number.

3. A number (except 0) is multiplied by 1, and the product is equal to this number.

3. The commutative, associative, and distributive properties of integer multiplication are equally applicable to fractional multiplication

1. Multiplicative commutative law: a b = b a

2. Multiplicative associative property: (then the pants a b) c=a (b c)3. Multiplicative distributive property: (a+b) c=ac+bc ac+bc=(a+b) c

Fourth, the method of finding the reciprocal:

1. Find the reciprocal of the fraction: swap the position of the numerator and denominator.

2. Find the reciprocal of an integer: Treat the integer as a fraction with a denominator of 1, and then exchange the position of the numerator and denominator.

3. Find the reciprocal of the band fraction: turn the band fraction into a false fraction, and then find the reciprocal.

4. Find the reciprocal of the decimal number: turn the decimal into a fraction, and then find the reciprocal.

5. Surface area:

1. The area of the triangle = the height of the base 2. Formula s=a h 22, area of the square = side length The side length formula s=a2

3. The area of the rectangle = length and width formula s=a b

4. The area of the parallelogram = the base height formula s=a h5, the area of the trapezoid = (upper bottom + lower bottom) height 2 formula s = (a + b) h 2

Grade 6 Mathematics Compulsory Knowledge Points:

1. Multiplication of fractions.

Fractional multiplication has the same meaning as integer multiplication, which is a simple operation to find the sum of several identical additions.

2.The calculation rules of fraction multiplication are like reeds.

Multiply the fraction by the integer, use the numerator of the fraction and the product of the integer multiplication as the numerator, and the denominator remains unchanged; Multiply fractions by fractions, use the product of the multiplication of the numerators as the numerator, and the product of the multiplication of the denominator as the denominator. But the numerator denominator cannot be zero.

3. The meaning of fraction multiplication.

Multiplying fractions by integers has the same meaning as integer multiplication, which is a simple operation to find the sum of several identical additions. Multiplying a number by a fraction can be seen as finding out how many fractions of the number are.

Brief introduction. Addition of fractions with the same denominator. The same denominator fraction is added, the numerator is added, the denominator remains unchanged, and the offer fraction can be reduced.

Subtraction of fractions with the same denominator. Subtract the fraction of the same denominator, subtract the numerator, and the denominator remains unchanged, and the offer fraction can be reduced.

Addition of different denominator fractions. The fractions of different denominators are added together, and then calculated according to the law of addition of fractions with the same denominator.

Heterodenominator fraction subtraction. The fractions of different denominators are subtracted, first through the fractions, and then the shielded state is calculated according to the law of subtraction of fractions with the same denominator.

Pinyin: 1Initials, finals, overall recognition, letters.

2.Standard rules: Don't let go when you see a mother, there is no A mother looking for o, e, i, and you to be marked in the back.

The rule omitted from the previous two points. (When you meet J Q X, take off the black yarn hat).

Kanji: 1Basic strokes, regular stroke order, radicals, and frame structure.

2.Dictionary Lookup: Be proficient in using phonetic sequence and radical lookup.

3.Homophones, polyphonic characters, and similar words. (Be able to accurately recognize the new words required to be mastered by elementary school students, as well as the various phonetic and group words of polyphonic characters, and distinguish similar words.) )

Words: 1Idioms, afterwords.

2.Quantifiers and the usage of "of, place, de". Be able to accurately fill in the usage of quantifiers, places, and nouns that are suitable for each other

The modifier in front of the word is connected with the word "of" as the definite clause of the noun;

The modifier in front of the verb is connected with the word "earth" as an adverbial verb;

The supplementary and explanatory components after the verb or adjective are connected by the word "de" as the complement of the verb or adjective. "Earth" is followed by a verb, such as to sing aloud; "of" is followed by a noun, such as my fountain pen; "De" is followed by an adjective, such as running fast.

Sixth grade. 3.Categorization of synonyms and antonyms. Be proficient in filling in synonyms and antonyms of words.

4.Imitation of words. Write words in the same form by following the examples given.

Such as: AABB (happy), ABB (green), ABCC (radiant), AABC (relish), ABAB (discuss) 5. Eight commonly used related words.

3rd grade. Sentence:

1.Expand sentences, shrink sentences, and organize sentence order.

2.Figures of speech used in sentences. (Common rhetorical devices include: metaphor, personification, rhetorical question, question, repetition, comparison, exaggeration, contrast.) Be able to accurately state the rhetorical devices used in a sentence and briefly state their effects. )

3.The interchange of four sentence forms: a declarative sentence, a word sentence, and a word sentence; b. Affirmative and negative sentences; c. Declarative sentences and rhetorical questions; d. Interchange of direct and indirect narratives.

4.There are eight types of sick sentences: a. incomplete components; b. Word order is reversed; c. Improper use of words; d. Inconsistencies; e. Improper collocation; f. Repetition of meaning; g. Improper classification; h. Unclear designation.

5.Recitation and dictation of aphorisms, classic poems, and 80 ancient poems necessary for the beginning of the elementary school.
