Oh my God, that's amazing! A complete collection of primary school math formulas carefully compiled by retired teachers actually contains the formulas commonly used in all grades of primary school, which is simply a math book for primary school students! If you have elementary school students at home, this is definitely a must-have! Imagine that as long as the children memorize the content of these 12 pictures, the math score in primary school will not be lower than 95 points, this is not a dream, but a reality within reach!
In addition to those boring math formulas, this material also includes elementary school math formulas, allowing children to memorize these basics in a relaxed and happy atmosphere. I have to say that this retired teacher is really well-intentioned, combining these formulas with smooth words, so that children can also feel the fun of mathematics in the process of memorization.
Let's take a look at a few of the slips in this profile!
The first slip is: "Head by head, tail by tail, tail by tail." "This slip is used to memorize the distributive laws of multiplication. For example, (a+b) c=a c+b c, the head multiplies a and c, the tail plus the tail adds b and c, and the tail multiplies b and c. In this way, children will be able to easily memorize the distributive law of multiplication.
The second slip is: "Odd multiplies odd number, and the result becomes even; Even numbers multiply even numbers, or even numbers go. This slip of the tongue is used to memorize the law of multiplying odd and even numbers. Multiply the odd number by the odd number, and the result must be even; Multiply an even number by an even number, and the result is still an even number. This rule is very helpful for children to understand parity and multiplication.
The third slip is: "The area is equal to the length times the width, and the circumference is twice as long and wide." This slip is used to memorize the area and perimeter formulas of the rectangle. The area is equal to the length times the width, and the perimeter is equal to twice the length plus twice the width. With this slip of the tongue, children can quickly recall the basic formula of the rectangle.
In addition to these slips, this material also comes with supporting examples to help children better understand and apply these formulas. These examples not only explain each step in detail, but also give answers and explanations, so that children can continue to improve in the process of practice.
If your child is struggling with math, don't rush them to a tutorial class, let them understand and memorize this material first! It is believed that as long as the children memorize and understand these formulas carefully and slip smoothly, their math scores will definitely improve. Moreover, through the knowledge that they have worked hard to master, it will also make children more confident and fulfilled.
When it comes to elementary school math basics, here are some detailed examples:
Integer and decimals:
Addition and subtraction of integers: For example, 5 + 3 = 8 and 10 - 4 = 6. Add and subtract with an intuitive counting method or by using a number axis.
Addition and subtraction of decimals: e.g., 03 + 0.2 = 0.5 and 08 - 0.4 = 0.4。Decimal addition and subtraction requires aligning the decimal points and then adding and subtracting them bit by bit.
Multiplication and division of integers and decimals: e.g., 4 3 = 12,05 × 2 = 1.0，12 ÷ 3 = 4，10 ÷ 0.5 = 20。In multiplication and division, decimal multiplication requires moving the decimal point, and division requires finding the quotient of integers by expanding the dividend and the divisor.
Addition and subtraction of fractions:
Addition and subtraction of fractions: For example, 1 2 + 1 4 = 2 4 + 1 4 = 3 4. Fraction addition and subtraction requires finding a common denominator and then adding or subtracting the numerator.
Multiplication and division of fractions: e.g., 1 2 2 3 = 1 3 (numerator multiplied by numerator, denominator multiplied by denominator), 3 4 1 2 = 3 4 2 = 3 2 (division converted to multiplication).
Proportions and percentages:
Ratio: For example, 3:4 represents the ratio of 3 to 4. Proportions are used to compare the relative size of two numbers or groups of numbers.
Percentage: Percentage is a way of expressing proportions, such as 25% for 25 out of every 100 copies. Convert decimals to percentages, such as 025 translates to 25% as a percentage.
Geometry: The area and perimeter of the base shape: For example, the perimeter of a square is 4 times the length of its sides, and the area is the square of the side lengths. The area of a circle is multiplied by the square of the radius, and the circumference (or the circumference of a circle) is 2 times the radius.
Angles and Triangles: Learn the concept of angles, such as a right angle is 90 degrees and a flat angle is 180 degrees. Learn about the types of triangles, such as equilateral triangles, isosceles triangles, and right triangles, as well as their properties, such as the sum of the inner angles of a triangle is 180 degrees.
Time and currency:
Time: Learn the concepts of clock and time, such as hours, minutes, and seconds. Learn how to read time, calculate elapsed time, and more.
Currency: Learn the denomination of currencies, such as yuan, jiao, and cent. Learn how to add or subtract simple currencies, such as settling when you make a purchase.
These examples are just some of the basics of elementary school math. Primary mathematics also includes many other contents, such as data collection and collation, probability and statistics, etc. Through the study of these basic knowledge, students are able to build the basic concepts and skills of mathematics, which will lay a solid foundation for further mathematics study.
In short, this primary school math formula book is a very practical resource, not only contains the formulas commonly used in all grades of primary school, but also has smooth and auxiliary examples, so that children can learn math in a relaxed and happy atmosphere. If you have primary school students in your family, you may wish to ask them to memorize this information, and I believe that their math scores will definitely improve!
Dear parents, in the festive atmosphere of the Spring Festival, please don't forget to invest in the children's math learning.
