Calculation is very important. If you are small, you should get into the good habit of not making mistakes in calculation. First, don't make mistakes in the calculation of rules, no matter whether you can learn the simple algorithm in Olympic numbers or not. Don't suffer big losses because of small mistakes in mathematics.
Even if the score is one point, it is still very important. How many people can fall behind the two candidates on the playground because of one point in the college entrance examination?
After strict exercise in calculation, we should practice according to the mathematical formula and application problem analysis learned in the fourth grade.
Not only do you have to calculate the color, but you also have to take a math problem and form the corresponding problem-solving ideas in your mind in order to calculate the accurate results.
Math problems in primary schools are not too difficult. We should understand the formula we have learned and use it in peacetime. If you learn by rote, you will only be confused and make mistakes in ambiguous situations.
Understanding memory is necessary. Teaching children to derive other formulas through a basic formula can not only enhance the memory of formulas, but also find certain rules from derivation.
It is easy to get full marks in fourth grade mathematics. As long as you are careful enough and have the idea of doing the problem, it is easy to do it, and it is all right.
