Calculation is an important basic knowledge in primary school mathematics,
The strength of students' computing ability
No, it is directly related to his interest in learning mathematics. The calculation ability of primary school students is mainly reflected in the table.
Whether the calculation is correct now,
Fast and flexible,
Which is what we usually call it.
"By the way,
Come on,
Coincidentally, "
. How to improve students' computing ability? Please talk about my own humble opinion.
The teacher gave advice:
First, create an environment, stimulate interest, cultivate quality, and let students say:
"I can do it"
"Interest is the best teacher"
I think teachers should create specific teaching situations,
Rangxue
Students explore new knowledge with a strong thirst for knowledge.
Let the boring calculation teaching come alive.
Interesting, establish students' self-confidence, make students willing to learn and do, and let students say:
"I can do it"
Explain to students typical examples of Chinese and foreign mathematicians or short stories related to classroom teaching content.
Second, stimulate interest. For example, before teaching simple operations, I will explain mathematics to students first.
Economist Gauss creatively answered "
1+2+3+
+99+ 100
"this
100
Sum of natural numbers
Story, create a good learning situation for students, stimulate their interest in learning mathematics, students do not
Consciously produced the idea of comparing with mathematicians.
Therefore,
The students examined the questions more carefully than before.
The analysis of the characteristics of the topic is more detailed than before, and the relevant laws and rules can be used flexibly to find it.
The law of solving problems enhances the interest in learning.
According to the negligence of the students,
Unstable,
Easily influenced by external and some internal factors.
The characteristics of the influence of elements,
Teachers should arrange the time and quantity of exercises reasonably,
adopt
"In a very short time,
The method of "a few times" can avoid students' fatigue and boredom and make students take notes.
Intention can be stably concentrated on the exercise object, thus ensuring the accuracy of calculation.
In view of the characteristics that primary school students are afraid of difficulties when they see difficult problems and simple calculations, I take "daily"
A question "
、
"the problem of finding a house"
、
"Who is the ever-victorious general?"
、
"My solution is the strangest-
A question
The method of "multiple solutions to one problem" encourages students to overcome difficulties and cultivate kindness in competition.
Temperament.
During the implementation of the above method,
I asked the students to design a statistical chart.
record
Your own achievements; Design a statistical chart for each group, record the achievements of the group, and evaluate it regularly.
Great. This not only improves students' computing ability, but also cultivates students' competitions and teams.
Spirit.
Second, all-round guidance, reasonable training, let students say:
"Me too."

, all-round guidance.
(
1
) Let students fully "talk"
, combine operation with language. Change past calculations
Teaching is a method to let students "calculate" and let them "speak" fully.
,
Speak your mind.
Cheng, and give appropriate guidance.
,
Give students a good way of thinking.
Meanwhile, pay attention to teachers and students.
Demonstrate the function of the operation.
,
Combine operation with language.
,
Strengthen students' intuitive understanding, including
Effectively develop students' thinking.
.
take for example
：
Professor Cai

When addition is performed internally
,
Let students fully "
"said at the same time.
,
Do it at the same time
,
Think and think.

Let students experience the process of "rounding"

Reasonable training
(

)
Practice oral arithmetic every day. Use every day
five
Strengthening students' oral arithmetic training in minutes
,
Single plan
According to the students' mastery, focus on practice.
What is difficult for students to master and what is easy to make mistakes should be highlighted.
practice There are many forms of exercise.
,
take for example
：
Win the red flag, race, relay race, oral swimming.
Play and so on.
(

) Contrast exercises. I am teaching.
,
Put the confusing and error-prone questions together and let the students
Distinguish and compare through purposeful exercises.
,
Let the students correct their mistakes and improve their discriminating ability.
Force, and timely evaluation of students' homework, correct mistakes.
(
three
) correct the mistake. The teacher deliberately put the typical mistakes in the students' homework on the blackboard to study.
Students point out mistakes, explain their reasons and correct them. Teachers should be timely
Find problems in students' homework and collect wrong questions.
,
Take an error correction class regularly, so that
Student consultation
,
Be a "wrong doctor"
Repeated practice can prescribe the right medicine.
Third, overcome carelessness.
,
Cultivate habits
,
Let the students say
：
"I can really do it."
.
I summed up from the teaching practice:
Lack of serious study attitude and good study habits,
It's a number
Learn the main causes of calculation errors.
Therefore,
We must pay attention to cultivate good computing habits.
To cultivate students' earnest and meticulous learning attitude, teachers must start from bit by bit.
Start with strict requirements for students, and be strict with mistakes caused by carelessness in students' homework.
Never tolerate it, and never let students "do nothing because of careless mistakes."
Ideologically, it is necessary to establish the idea that "you can do the problem without being wrong".

Pay attention to writing. Students are required to carefully write Arabic numerals and operation symbols according to the format.
Correct handwriting can effectively avoid "misreading". Teachers should take the lead.
model
,
There are clear requirements for students.
,
Be careful in homework design.
,
Avoid students' coping psychology.
2
, clear the exam questions. I think this is the first condition for correct calculation.
,
Review the sum of the numbers when reviewing the questions.
Symbol,
See what's the connection between them.
Also review the operation sequence,
Know what's most important,
After what?

Simple and easy.

Be aware of this problem before doing it.
