How to improve the fun and effectiveness of the design of calculation exercises for junior students

How to improve students' numeracy ability, we should start from the lower grades, and I think the key is to improve students' numeracy ability from the following four aspects. 1. Good "oral arithmetic" is the prerequisite for the success of "calculation" The Compulsory Education Mathematics Curriculum Standards point out: "To cultivate students' numeracy ability, we should pay attention to basic oral arithmetic training, which is not only the basis of written arithmetic, estimation and simple arithmetic, but also an important part of computing ability.

In the teaching of multiplication formulas in the second grade, I pay special attention to the teaching of oral arithmetic, and adopt flexible teaching methods to let students master the formulas. After that, to establish a mantra test book, firstly, each student must be able to fluently recite the multiplication mantra from 2 to 9, refine to the mantra from 5 to pass, and then pass the mantra of 2 and other formulas, and then the teacher personally checks the mantra recitation of each sentence, for the students who pass, the teacher gives extra points on the mantra test book, which not only achieves the knowledge goal, but also improves the interest of the students, and also motivates the students. Second, have the students who can recite the multiplication formulas from 2 to 9 recite backwards.

In this way, after two months of hard work, I used all the time I could to listen to the students recite the mantra thousands of times a day. In the end, I succeeded, and the students in the class were just as good as the top students, with a 100% accuracy rate. In the third grade, two-digit multiplication is performed.

If it's oral arithmetic, it's a lot of practice, repeated practice, practice makes perfect. If it is a written arithmetic or simple arithmetic, then it is necessary to teach the child some practical tips and practice more.

Practice more, summarize frequently, and observe. Sticking to 5 minutes a day can be improved.

Make some card exercises or play 14 hook fish with your child with playing cards.

If you need to memorize the multiplication formula, no matter how large the number is, you have to add and multiply a single number, and the addition and multiplication of multiple digits can also be modified in a simple way to calculate, you can go to learn some tutorials, and many simple operation methods are now very popular.

There are three main aspects of a person's mathematical computing ability:

1. Accuracy of calculation results;

2. Skill of calculation method;

3. Quickness of calculation speed.

In order to improve the mathematical calculation ability of primary school students, we should work hard from the following four aspects:

1. Let students be proficient in arithmetic regulations: In primary school, students should learn three types of numbers - integers (natural numbers), decimal numbers and fractions, and these three types of numbers must perform four operations - addition, subtraction, multiplication, and division.

2. Pay attention to cultivating students' estimation ability: The new curriculum includes the cultivation of students' estimation ability, which fully reflects the importance of estimation in mathematical calculations and practical life

1. Help us predict the calculation results;

2. It can improve the ability of mathematical analysis;

3. Able to solve practical life problems;

4. Check whether the results are basically correct.

3. Effectively strengthen students' oral arithmetic training: In the classroom, the following steps are generally taken to carry out oral arithmetic training:

1. Let the students calculate the results first.

2. Let the students talk about their own oral arithmetic methods, affirm good oral arithmetic methods in a timely manner, and sometimes ask students if there are other oral arithmetic methods for the same topic.

3. Finally, the teacher explains and emphasizes the oral arithmetic method.

Fourth, good at taking simple algorithms: some mathematical calculation questions have obvious formal and numerical construction characteristics, these characteristics are a great opportunity for us to use simple algorithms, through a certain number of simple calculation exercises, not only improve students' observation and analysis ability, and gradually strengthen students' mathematical calculation skills and quickness, but also bring students a happy spiritual enjoyment, which is of great benefit to stimulate students' interest in learning mathematics.

Strengthen the teaching of oral arithmetic skills. Among the four arithmetic, people commonly use written and oral arithmetic. Written arithmetic is inseparable from oral arithmetic, and the formation of written arithmetic skills is directly restricted by the correctness and proficiency of oral arithmetic.

Guide students to participate in the derivation of laws and formulas. It is necessary to constantly create conditions to guide students to use their hands, brains, practice, and observation, and take the initiative to explore and participate in the process of deriving laws, formulas, laws, and properties.
