According to previous years' experience, interview topics are generally selected from textbooks of grades 3-5.
The test sites frequently tested in previous years are:
The meaning of the score.
Organization.
Addition and subtraction of fractions with the same denominator.
The formula for calculating the sum of the internal angles of a triangle and the area of four parallel sides can be divided into two parts.
Fractional addition and subtraction
1, add and subtract fractions with the same denominator, the denominator remains the same, that is, the decimal unit remains the same, and add and subtract numerators to reduce the bid score.
2. Add and subtract the scores of different denominators, divide them first, that is, use the basic properties of scores to convert the scores of different denominators into the scores of the same denominator, change the unit of scores and keep the size unchanged, then calculate by adding and subtracting the scores of the same denominator, and finally make a quotation score that can be reduced.
Multiplication and division
1, the fraction is multiplied by the integer, the denominator remains the same, the numerator is multiplied by the integer, and finally the score that can be reduced is quoted.
2. The score is multiplied by the score, the numerator is multiplied by the numerator, and the denominator is multiplied by the denominator, and finally the offer score that can be reduced is obtained.
3. Fraction divided by integer, denominator unchanged. If the numerator is a multiple of an integer, divide the numerator by the integer, and finally you can reduce the number of offer points.
4. Fraction divided by integer, denominator unchanged. If the numerator is not a multiple of an integer, multiply this score by the reciprocal of the integer, and finally the offer score can be reduced.
5, the score divided by the score is equal to the dividend multiplied by the reciprocal of the divisor, and finally the offer score that can be reduced.
