Computation Methods for Fifth Grade Math

Fifth-grade math is a transitional math as students begin to work with fractions, decimal points and beginning algebra in the form of geometrical ideas. Students in fifth grade usually use several computation methods in order to find the answers to math problems and to advance in their own math skills.

Mental Computation

In fifth grade, mental math is just starting. Before fifth grade, students really need to write things down in order to see answers. By fifth grade, however, they should have learned enough basic addition, subtraction, multiplication and division facts to start to do simple mental math computation. The method for mental math computation is simple: Students look at a problem written on the board and solve it in their heads. They are not allowed to write anything down. As mental math problems get more difficult, some teachers might allow students to write down solutions to part of the problem. For instance, if the mental math problem is 62+14-6 =?, teachers might allow students to write down the answer to 62+14, and then write down the answer to that number minus 6 in order to arrive at a final answer. As time moves on, students should be required to do the entire mental math problem in their head.

Written Computation

Students in fifth grade do the majority of their computations using a pencil and paper, as they have done since they started solving math problems. Students should still practice long division, multi-number multiplication and fractions with pencil and paper computation. They also should review multi-number addition and subtraction with pencil and paper computation methods. This method requires students to write out problems and then do the work on paper. Some problems, such as division, require guessing and checking with scratch paper, as well as showing work. Functions such as percentages, fractions, ratios, complex addition, subtraction, multiplication and division should be written out in stages so the teacher can see if a student understands what he is doing. Also, if a problem ends up with the wrong answer, the teacher can figure out where the student went wrong and provide directed input for him.

Calculator Computation

In fifth grade, most teachers allow students to use calculators for the functions that they already know how to do in order to speed up the process. In earlier grades, students should not use calculators for tasks such as addition, subtraction, multiplication and division because they are still learning those skills mentally, and a calculator will bar them from learning further. In fifth-grade math, calculators can be used for the four main functions.

At this age, students should not use calculators to figure out percentages, fractions, or ratios because these are things that need to be learned in fifth-grade curriculum and should be learned first mentally and on paper.

Mental arithmetic teaching children on the abacus Abacus (Abacus) in the center «Pythagoras»

Let’s start a little from afar. You have probably come across such statistics — only 5% of people achieve significant success in life. The remaining 95% only dream about it, but for some reason their dreams do not come true.

Why is this happening, and can we change these statistics for our children?

Science has proven that the ability to succeed depends on the harmonious development of the right and left hemispheres of the brain. Unfortunately, in most of the world’s population, the development of the left hemisphere significantly predominates over the right. In other words, logical thinking is well developed. But creative thinking — intuition, choosing the right paths and actions — works very badly. nine0003

It turns out that if you and I develop the right hemisphere to the level of the left, then we will gain the ability to succeed?

To some extent, yes. But much more serious results will be achieved here not by an adult, but by a child of 5-12 years old. It is at this age that the brain is most plastic. Therefore, our technique is designed specifically for children.

What is Mental Arithmetic?0003

• is suitable for children from 4 to 16 years old;

• develops independence, initiative, the ability to critically evaluate oneself;

• is already operating in 52 countries (USA, Canada, UK, Austria, Spain, Australia, Japan, Malaysia, Thailand, China, etc. ).

The abacus is called the «ancient calculator» — our ancestors invented it 2500 years ago. Why is this system of computing popular again today? nine0003

The fact is that, unlike ordinary arithmetic, exercises on the accounts involve both hemispheres of the brain. Moreover, their development is coordinated and harmonious. What results in… Do you remember what we talked about at the beginning?

How it happens

Development of the left hemisphere:

• stimulation of fine motor skills;
• visual representation of the result of arithmetic operations.

Development of the right hemisphere:

• use of both right and left hands equally;
• mental work with imaginary accounts.

A «side effect» of the technique is quick mental arithmetic

Here is an example: in Japan, children are required to study soroban (Japanese abacus) in elementary grades. This approach to education has already yielded results. Japanese schoolchildren win international mathematical olympiads year after year, which has even become a tradition. nine0003

In China, children already know how to solve problems with three-digit numbers in kindergarten. Take a look for yourself — it seems incredible, but it is a fact:

However, the meaning of Mental arithmetic is not at all in the ability to calculate in the mind. It’s just a beneficial side effect. And the abacus itself is not a «calculator» and not even a mathematical simulator.

Mental arithmetic develops the ability to succeed in any business

Mental arithmetic classes help train the neural connections in your child’s brain, develop the speed and quality of his thinking. This can be compared to sports training. nine0003

Imagine that suddenly…

You are among the participants in the World Cycling Championship. The start signal is about to sound, and the last time you rode a bike was in the 5th grade. Do you have a chance among athletes who have trained this skill for several years?

It is the same with the intellect. Verified: with any tasks in school, career, hobbies, etc. A trained brain can do it easier and faster than an untrained one.

Let’s continue the sports analogy. To become an Olympic champion, you need to practice sports from childhood. It’s the same with mental arithmetic. According to Chinese and Japanese teachers, if an adult and a child start practicing on the abacus at the same time, the adult will not achieve the same results as the child. That is why it is important to start training the brain on time. nine0003

What does mental arithmetic give your child (according to our parents)

The program is designed for 2 years, but parents usually notice the first results after 3-4 months.

Growth in school performance (even in music school)

Self-reliance and self-confidence

• Katya became collected and self-confident, she says: “I will do it anyway!”. She has become so independent that I can safely entrust her with the completion of a difficult school assignment without my participation. nine0090 (Marinina Elena Anatolyevna).

• My son has been attending classes for 3 months, so it’s too early to talk about any global changes. But the fact that he now does his homework on his own is for sure. (Lyachina Irina).

Victories in competitions and olympiads (not only mathematical ones)

How the lessons go

Your child trains the skills of working with accounts gradually, with the transition from simple to complex. Classes are held 2 times a week for 1 hour plus homework for 15 minutes a day. As a result, by the end of the program, your child is already freely adding, subtracting, multiplying and dividing two- and even three-digit numbers in his mind. nine0003

But the question is: can a normal child do the same thing diligently for an hour? Of course not! And so we came up with this. ..

A special mental arithmetic program from «Pythagoras»

The tradition of exercises with abacus came to us from Asia, where children are much more obedient, and the authority of the elders is indisputable. There is no concept of «boring in class», but there is strict discipline. Another thing is our children. Practice shows that long-term training on the accounts is difficult for them, fatigue and loss of interest occur. nine0003

Therefore, we alternate lessons on the abacus with games, tasks for the development of memory and attention, exercises for the eyes and posture. It turns out a double benefit!

But that’s not all.

Teaching Mental arithmetic is often offered by analogy with school lessons — in groups, according to a general plan. At the same time, the individual (genetic) characteristics of the child are not taken into account at all. For example, one person will have time to solve 3 pages of a textbook per lesson, and the other only 1 or even half. All children are different, each has its own speed. nine0003

Our children also study in groups. But at the same time, tasks are given to each child individually, taking into account his abilities. Therefore, we have fun, interesting and productive!

In contrast to the English courses, the son never once said about mental arithmetic: «Mom, why don’t we go?» We were impressed by the results, so we are planning to enroll our six-year-old daughter in this course as well. (Pronina Maria Sergeevna).

Here’s how the Mental Arithmetic classes at Pythagorka go:

Your child is taken care of:

• teachers and psychologists with experience working with children in kindergarten and school;

• teachers of the highest category;

• winners of regional and all-Russian competitions of pedagogical skills.

All our teachers have been trained in the «Mental Arithmetic» technology at the WORLD SORABON Center (Izmir, Turkey).

Textbooks

At the Pifagorka Intellectual Development Centers, all children are taught according to the author’s textbooks, developed taking into account the age and developmental characteristics of children.

Textbooks are printed on high quality paper with beautiful colorful illustrations. They will become real helpers for your children!

Archans became the winners of the international Olympiad in mental arithmetic

District news

Reseda Khakimzyanova,

They can add and subtract two-digit and three-digit numbers in seconds. Without a calculator. In the mind. They work only with fingers.

525+126+37… Did you solve the example? Or, in search of a calculator, did your hands reach for your smartphone? Ibragim Fattiev and Suleiman Saifullin, who live in Arsk, “click” such examples as nuts. Although the boys this year go only to the second grade. At the end of June this year, they participated in the International Olympiad in Mental Arithmetic, where Ibrahim took first place, and Suleiman — second place. Among 250 participants from 18 countries. The Olympics were to be held in Turkey. But due to the reduction of flights, the organizers decided to organize it in an online format. nine0003

“Mental arithmetic is not just mathematics”

Zukhra Khozhaeva studied with Ibragim and Suleiman at the Arsky Palace of Schoolchildren. Despite the fact that she is now on maternity leave, she continues to work with them. Education teacher of mathematics. She took special courses in mental arithmetic.

“In Russia, mental arithmetic appeared about 5 years ago. This is a South Korean technique, — says Zukhra Khozhaeva . — Mental arithmetic is not just mathematics, it is a simulator for the brain. Most parents believe that this technique is aimed at developing rapid mental counting. Yes, indeed, your child will learn to count quickly. But this is far from the main plus from doing mental arithmetic. In fact, the child will develop many other qualities that will be useful to him in everyday life. Mental arithmetic brings up such qualities as multitasking, composure, attentiveness, concentration. After a course of study, the left and right hemispheres of the brain begin to work simultaneously in the child. nine0003

First, children learn to count on the abacus. This is a special account. Ibrahim and Suleiman showed us how to work with him. Working with the «knuckles» develops fine motor skills. After the children get used to working with the abacus, it is gradually abandoned. Mental arithmetic is different from ordinary math classes. But these two systems do not interfere with each other. For example, if at school children learn column addition, then at school they do just that.

«There is a benefit»

Advertising

The teacher calls the numbers, and Suleiman and Ibrahim answer in turn. Their «burning» eyes already indicate that they are interested in this direction. «You like?» We asked the boys. «Yes,» they answered at the same time. Ibrahim and Suleiman study at the Arsk school No. 1 in the same class.

“We have been doing mental arithmetic since the age of 5,” says Ibragim’s mother Gulnaz Fattieva . – We are the first students of Zukhra Khozhaeva. I myself am active, and I bring up children by my own example. We ended up in the mental arithmetic class quite by accident. I wanted to enroll my son in some circle and for this purpose came to the Palace of Schoolchildren. And there they gathered those wishing to do mental arithmetic. We decided to try. My son loves it and so do I. Mental arithmetic also develops memory. We are happy to participate in various Olympiads. Of course, participation in them is paid, but I think that they are very necessary. Such Olympiads are organized and colorful. Children communicate, get acquainted with their peers. During international olympiads, they learn to treat representatives of other nationalities with respect. We were already planning to go to Turkey, we wanted to buy tickets. But due to the reduction in flights, the Olympiad was held online. But everything was fair. Assignments are received only on the day of the Olympiad. The child must be alone in the room. In front of him is only a computer, an abacus and a piece of paper with a pen. The course of the Olympiad was filmed and sent to the organizers. nine0003

The day before, Ibragim was invited to the city of Derbent. “We were invited to the All-Russian competition in mental arithmetic, which will be held on City Day. I can’t say yet whether we can go or not. But I really want to,” says Gulnaz Fattieva.

Gulnaz khanum’s activity causes admiration. A mother of three children, she works as a paramedic at an ambulance station and at an oncology center in Kazan. “Sometimes you have to work every other day,” she says. At the same time, he finds time to take children to sections and circles. Ibrahim, in addition to mental arithmetic, is engaged in swimming and chess. nine0003

“My older daughters help me a lot,” says Gulnaz Fattieva. — They also study at the Arsk school No. 1. They study well. My children are independent. I have always approved of their desire to participate in various competitions and events. I am for an active lifestyle.

Suleiman’s talent for mathematics was noticed by his mother Zilya Saifullina in childhood.

“When we were just walking down the street, I often gave him simple tasks. For example, two crows are sitting on a branch, one flew away, how much is left. He answered. Then he was 3-4 years old, — says Zilya Saifullina . — He has been attending a choreographic circle since the age of 3. And the talent for mathematics, I think, passed to him from his mother-in-law. Therefore, I wanted to develop it in this direction. Seeing on social networks a set for classes in mental arithmetic, we decided to try ourselves. I didn’t even know what it was then. I thought it was just math. Then Suleiman was 5 years old. He already knew how to count and write numbers. But he wrote in a mirror. I learned how to write correctly in class. Now they can add and subtract. This year we will start learning multiplication and division. The knowledge gained also helps in school. Both Suleiman and Ibrgaim became winners of the school mathematics olympiad.” nine0003

Zilya Saifullina is also for comprehensive development of children’s talent. “The talent of a child must be developed from childhood,” she says. Suleiman is also engaged in choreography, chess.
