How to teach toddlers to learn addition and subtraction within 10

Step 1: Let your child learn to count proficiently. The requirements are:

I can count down from "1" proficiently.

Be proficient in starting with a number in the middle. For example, the teacher says: Count from 4; Start counting with 12.

Skillfully counts down from a number in the middle. Example: The teacher says: Count down from 4 and count down from 12.

Counting is a learning content in small classes, and our teachers think that every child should be able to do it. However, we ignore that many children only start counting with "1", and if you ask them to start counting with a number in the middle, they may not know how to count. Or that the child doesn't know how to jump up an integer like -30.

Step 2: Let the child skillfully grasp the relationship between numbers

For example: What is in front of 5? How many are in the back? What is in front of an 8? How many are in the back? Count from 5 forward, count backward, from.

11 Count forward, count backward.

The third step is to let the child master the relationship between the size of numbers: for example: which is bigger, 7 or 8? Which is bigger 12 vs 4?

The fourth step is to let the child learn to read the questions. Many children can read the questions, but they can't read them. The child knows how to "+", but not how to read it. When asking the child to read it out for the next calculation, tell the child that when he reads "add", that is.

Count backwards. When you read the sign of "minus", you are counting forward.

The fifth step is to teach children to know the single digit and the ten, so that the child can skillfully say what the single digit is in the two digits and what the ten digit is.

For example: 15, the single digit is 5, and the ten digit is 1

Step 6: Teach your child to do calculations:

1. Counting finger addition and subtraction:

Addition e.g. 15+2=

We tell the child: keep the big number 15 in your heart and the small number 2 with your fingers (let the child.

Zi stretches out his finger), and the middle is the "+" sign, which is to start with the number after 15 and point the finger after 15.

It's 16, and two fingers are , so it's 15+2=17

Subtraction e.g. 15-2=

We tell the children: put the big number 15 in confidence, and the small number 2 with fingers (let the child.

Stretch your finger out), the middle is the "-" sign, that is, the countdown starts from the front of 15, 15 is preceded by 14, and the last 2 fingers are 13, then 15-2 = 13

Addition e.g. 15+2=

We tell our children that the sum of the single digits is 5 + 2 = 7, and the addition of the ten digits and the ten digits is the sum of the ten digits.

1, then 15+2=17

For example: 15-2=, we tell the child that the subtraction of the single digit is 5-2=3, and the subtraction of the ten digit is the subtraction of the ten digit.

1-0=1, then 15-2=13

Relatively speaking, the "counting fingers" are only suitable for addition equations where one of the two numbers is singular, because if both numbers are double, then the fingers are not enough; Although it is difficult to learn the "addition and subtraction of individual and ten" methods, it can be applied to all calculations, and from the perspective of sustainable development, I recommend using "addition and subtraction of individual and ten digits".

Let your child learn to count proficiently.

Arithmetic is more complicated, and it is difficult for children to accept if they are taught more difficult arithmetic at the beginning. Parents can integrate life into their children's mathematics learning, and combine objects expressed with the concept of quantity, so that children can count proficiently.

Able to write numbers.

Through pictograms, children can memorize numbers and be able to write them. 1 is thin and long like a pencil, 2 is like a duckling floating on water, 3 is like ears to hear sounds, 4 is like a red flag fluttering in the wind, 5 is like a scale hook to weigh things, 6 is like a bean sprout grinning, 7 is like a sickle cutting grass, 8 is like a gourd can make a scoop, 9 is like a spoon to eat, 10 is like an egg and refueling sticks.

Teach children with real-life examples.

Parents can ask their children to wash two apples, eat one for each person, and ask how many apples they have. In this way, children can be exposed to mathematics and learn mathematics unconsciously in their lives, which can improve children's interest in mathematics and help children understand the importance of mathematics in life.

Consolidation. Parents should use all available time to give their children questions. As long as there is a free time, you can ask questions and speak quickly, which gives the child a sense of urgency and can exercise his habit of thinking quickly and improving efficiency.

Parents can casually say -2 and so on, and as long as the child answers correctly, praise him, "awesome", "really good", "my child is so smart", etc.

Do the math. Parents need to cooperate with the daily 30 ways of addition and subtraction within 10 for the baby to improve the children's arithmetic ability, pay attention not to let the child count the fingers, form a habit that is not easy to change, and cultivate mental arithmetic ability.

Reward strategy. Give the child a timer for the question, and give the child a reward when he completes it, so that the child can feel his own progress and improve the fun of his practice.

Special Tips Don't teach your child too quickly, step by step, the effect is the most important.

Summary. Count from 1 to 10, then from 10 to 20, 10 to 10, and all the way up to 100. The key is not to rush, teach the child when he is willing to count, don't force him if he is not willing to count, take his time.

Then, when your child can count from 1 to 10, you can teach him to count objects. For example, apples and candy at home, a few people in the family, a few dishes, and a few things to buy in the supermarket, let him count them whenever he has the opportunity, don't be troublesome. It is only when applied to physical objects that children will have a concept of numbers.

Children can count at a stage, and more importantly, they count backwards, counting from 10 to 1, from 20 to 10, and slowly increasing. Don't think that countdowns are not important, only when you learn to count down, can you really be sensitive to numbers.

Now it's time to add, you can start with a simple start to teach the child, such as 1 + 1 = 2 1 + 2 = 3, first use the real thing, such as 1 + 1 you can take 1 apple plus 1 apple, 1 apple plus 2 apples, slowly let him deepen the concept of numbers, but the child does not have a real object in school, so teach him to use his fingers to calculate. Be sure to use the real thing to let him calculate first, and then teach him to use his fingers. Otherwise, he will rely on his fingers and not understand the true meaning of the numbers.

The steps to teach your child to add and subtract within 10 are as follows:

Materials: paper, pen.

1. We can first let the children know the numbers within 10, and the numbers within 10 are from 0 to 9, so that the children can have an understanding of what the numbers look like.

2. After the child knows the numbers, we begin to let the children write these numbers, and we can use number nursery rhymes to let the children learn to write numbers.

3. Then we decompose the numbers within 5 to the children and write them out, so that the children can know and understand, and memorize these points within 5.

4. Then there is the division of numbers within 5, which is the same as the above, and children also need to remember that after these will be, we are letting children learn addition and subtraction within 10.

5. Learn to be within 5, within 10 is simple, and the child will use both hands to calculate. Just ask your child to count his fingers slowly and do the calculations.

Breaking the Ten Laws:

Breaking ten is a calculation method, that is: when the single digit is not enough to subtract, subtract the subtraction with 10, and add the number of the remaining posture book and the number on the single digit, that is, break the ten method.

Addition to make up 10 formulas: look at the big number, divide the decimal number, make up ten, add the remaining number, children, clap your hands, everyone come to sing the song of making ten, one to nine, two to eight, three to seven to four to six, five to five to make up to ten.

Subtraction breaks the ten-law formula: minus nine plus one, minus eight plus two, minus seven plus three, minus six plus four, minus five plus five, minus four plus six, minus three plus seven, minus two plus eight.

Note: "Breaking the Ten Method" is not necessarily better than the direct subtraction method, the "Breaking Ten Method" used to attach great importance to the "Ten Method", and now more attention is paid to the thinking of students, what method students like to use, students should be encouraged to use what method, as long as it is easy for students to accept, you can. We advocate cultivating students' number sense, which is cultivated in computing, of course, in combination with specific problems, and choose the previous algorithm.

Today I saw a post by a mom on the forum discussing how to teach a child to do addition and subtraction above ten. I think it's better to get rid of adding and subtracting with your fingers earlier. After all, we only have 10 fingers, and in other ways like using a fist to represent 10, I think there's an extra thought process in between.

Obviously, after learning mental arithmetic, there is no problem with addition and subtraction within 100, and you can do mental arithmetic.

In fact, I have been thinking about this issue for a long time, although there are mixed opinions on mental arithmetic, and there are many people who oppose it, but we can consider it from another angle.

Mental arithmetic and Montessori, or we use real objects (such as apples), and we now use our fingers to help children understand the meaning of addition and subtraction, but the tools used are different, fingers in the early stage let children understand the operation within 10, let the child understand the correspondence of quantities, but there is no way to operate above 10.

Montessori uses golden beads as teaching aids, which are easy for children to understand, but according to my friend's children, after learning, they feel that the speed of operation is not fast, especially when carrying and subtracting, children have to think about how to go to the bank to exchange beads.

In comparison, when learning mental arithmetic, children are easy to understand, and it is easy to form a bead diagram in their minds, and there is no difficulty in learning addition and subtraction.

Recall that we have learned to calculate on our own, although we adults can now "calculate" the results of 7+8 in a very short time, but if we think about it, are we really calculating? Actually, no, it's because we have written down the results after understanding addition and subtraction after a long period of experience. Children learn addition and subtraction, we don't care what tools are used, as long as we can find the rules of operation through effective methods, and then write down the results of the calculations like us.

How to teach children more than ten addition and subtraction, first of all, you should let the child master the addition and subtraction within ten, proficient, and then you teach him more than ten addition and subtraction, to act can also be vertical, addition and subtraction are first counted one digit and then ten digits, so that slowly he will master it.

1. The concept of numbers: recognize numbers within 10.

Addition and subtraction within: Understand the meaning of addition and subtraction.

3. Geometric perception: recognize common geometric figures in life.

4. Interest in mathematics: Story-based learning, combined with life, stimulates children's interest in learning mathematics.

5. Interesting learning scenes to stimulate interest: boring mathematical calculations are integrated into life scenes, so that children can learn knowledge happily in interesting interactions and stimulate children's interest in mathematics learning.

6. Set up a test link to check and fill in the gaps in time: At the end of each school bag, there is a test link to test the knowledge that children have learned, so that children can check and fill in the gaps in time.

Educate the baby more than ten addition and subtraction, then you can let the baby take off the socks, count the feet and hands too, and then let him be interested, he will slowly.

Teach children to learn the methods of addition and subtraction within 10: the method of addition and subtraction with specific objects, the method of addition and subtraction with the method of counting up and down, and the method of adding and subtracting with the division and combination of numbers.

1. Use the methodology of specific objects to add and subtract

2-7-year-old children are still in the pre-arithmetic ability stage, that is to say, they do not have real arithmetic ability, children's thinking form focuses on specific image thinking, and is transitioning to mathematical and logical thinking, and 7-12-year-old children really have arithmetic ability. Therefore, according to the characteristics of the child's development, it can be added or subtracted by looking at specific objects.

We can integrate life into math learning, for example, take out 4 oranges on the table at home, you and your child eat one, and how many? The child can easily name the remaining 2.

This is to let children learn to add and subtract with specific objects, because it is a specific object, you can know it at a glance, so that children can learn mathematics addition and subtraction in life, and children will feel that mathematics is not difficult, which can not only improve children's interest in mathematics learning, but also make children realize the importance of mathematics in life.

2. Use the method of upward and downward numbers to add and subtract

When children learn to speak at the age of 1, we will unconsciously teach children to count, from 1 to 10, counting upright and reading backwards, and the child is very interested. It is often seen that when a child goes up the stairs, he will count the stairs while walking, and when he sees the numbers on the traffic lights and the numbers on the elevator floor, the children like to look at the numbers, which shows that the children have a great interest in counting from an early age.

Therefore, we can use the feature of counting to teach children to add "count up" and subtract "count down". The basic principle is: remember large numbers, up or down to count small numbers.

For example, 5+2=? After remembering 5, count two numbers up to get the result 7; 5-2=？After remembering 5, count down two numbers to get the result 3.

3. Methodological addition and subtraction of the division and combination of numbers

Just like elementary school students memorize multiplication formulas and middle school students memorize mathematical formulas and theorems, they are familiar with memorizing the division and combination of numbers. Children like to memorize in kindergarten, using the characteristics of children's good memory, let children recite the division and combination of numbers within 10, and memorize them well, and they will naturally add or subtract. This method will be learned in the first grade math textbook.

For example, 5 can be divided into 1 and 1, 1 and 1 to form 5, then with a little guidance, the child will think of 5 when he sees 1+4, and he will know that 1+4=5.
