How to let parents and children review singular and even numbers together?

How to let parents and children review singular and even numbers together? First, with the help of physical objects to help the baby understand the meaning of odd and even numbers.

Parents can use the child's spelling ** to arrange 10 rows, such as the baby counts the number of each line of spelling, and put the corresponding number card on the bottom of each row: ask the baby to put each line of spelling ** two pairs of two pairs together, and then guide the baby to observe, is each line of spelling ** can be placed together in pairs. Parents use their fingers to inspire their babies Two pairs of two pairs to the end, there is always one left unpaired, these numbers are singular Two pairs are arranged to the end just without the remaining, these numbers are even numbers, even numbers are numbers that can be paired in pairs.

2. Teach your baby to look for odd and even numbers.

Parents first ask the baby to find out which of their body organs are even and which are singular (such as eyes, ears, hands, and feet are even numbers; Head, nose, mouth is singular), and then ask the baby to find out which of the clothes on the body is singular, which is the double number (such as socks, shoes, gloves, etc. are double numbers, hats, scarves, belts, etc. are singular), you can also ask the baby to say which items in the home are singular, which are even numbers, and consolidate the understanding of odd and even numbers.

3. Let the baby operate and practice.

1) Counting: Parents put some candy in a small cloth bag, let the baby touch whether it is odd or even, and then pour it on the table to see if it is correct. Every time the baby touches the right one, parents will reward it to arouse the baby's interest in learning.

2) Classification of counting cards: Parents will write a number of cards with 1-10 times together, and ask the baby to arrange the number cards in two rows according to the odd and even numbers.

3) Listen to the number and say odd and even: Parents report a number, so that the baby is immediately odd or even. Counting backwards refers to counting in the opposite direction to the order of the natural sequence.

Teaching the baby to learn the reciprocal can enable the baby to grasp the order of natural numbers from the opposite direction, develop the baby's reverse thinking, and help the baby learn addition and subtraction.

It is not difficult to teach the baby to know odd and even numbers, as long as the parents have patience, perseverance and methods, they will definitely make the baby learn well, so as to better cultivate his logical thinking ability.

Extended information: 1) Odd numbers are another name for odd numbers in mathematics. In mathematics, as opposed to a double number (a positive even number), it can be expressed as a number of the form 2n+1 (n is an integer greater than or equal to 0).

2) Even numbers are another name for even numbers in mathematics. In mathematics, it is opposed to singular numbers (positive odd numbers), which can be expressed as numbers of the shape 2n (n is an integer greater than or equal to 1), and even numbers must be divisible by 2, and it is worth noting that 0 is not a double number (in 2002, the International Mathematical Association stipulated that zero is an even number, and in 2004, China also stipulated that zero is an even number), because 0 is not a positive number.

Parents can arrange 10 rows, ask the child to count the number of phonics in each row, and put the corresponding counting card at the bottom of each row: put each row of phonics in pairs, and then guide the child to observe.

How to teach children to even and odd?

1. With the help of physical objects.

Parents can arrange the phonics in 10 rows, let the children count the number of phonics in each row, and put the corresponding counting cards at the bottom of each row: put the phonics in each row in pairs, and then guide the children to observe whether the phonics in each row can be placed in pairs. Inspired by the fingers of the parents in pairs at the end, always leaving one unpaired.

The numbers are all singular: 2, 4, 6, 8, 10 are arranged in pairs at the end, and there is nothing left. These numbers are even, and even numbers are numbers that can be paired.

2. Operational exercises.

1.Counting: Parents put some candy in a small cloth bag, let the child touch whether it is an odd or even number, and then pour it on the table to see if it is correct. Every time the child touches the right one, parents will reward them to arouse their children's interest in learning.

2.Classification of counting cards: Parents put together several counting cards with a number of numbers of 1-10 times, and let the children arrange the counting cards in two rows according to odd and even numbers.

3.Listen to the number to say odd and even numbers: Parents report a number, so that the child will immediately be odd or even.

A countdown refers to a count in the opposite direction of the natural order. Teaching children to learn reciprocal numbers can help them grasp the order of natural numbers from the opposite direction, develop their reverse thinking, and help them learn addition and subtraction.

Kindergarten children like to play the game of "Find Your Five Senses", which contains the experience of odd and even numbers. Among the five senses, the singular number has the nose and mouth, and the even number has eyes and ears. If the teacher asks the child to point to his or her five senses before continuing to ask the question:

How many noses are there? They must be able to unmistakably say: "A nose."

How many eyes do you have? "Two eyes. And then the summary:

Oh, and there are two eyes, one on the left and one on the right, like two good friends. There is only one nose, and there are no friends like it. Through the guidance of the teacher, children can perceive that "1" is lonely, and the same "2" is companion.

After playing this game, it can be further expanded, allowing children to find out which body organs are only "1" in their bodies, and which have two "friends" like eyes and ears. In this search process, the toddler will focus on identifying and analyzing the number of organs, and although they cannot say words such as odd or even, this quantitative experience has already entered their minds.
