Parents can arrange 10 lines with the help of their children's puzzles. For example, the baby can count the number of spelling pictures in each row, and put corresponding digital cards at the bottom of each row: let the baby put the spelling pictures in each row in pairs, and then guide the baby to observe whether each spelling picture can be put together in pairs. Parents enlighten their babies with their fingers: 1, 3, 5, 7, 9 are all paired in the end, and there is always one who is not paired. These numbers are all singular: 2, 4, 6, 8, 10 finally paired, with no remainder. These numbers are even numbers, and even numbers are pairable numbers.
Second, teach the baby to find single and even numbers
Parents first let the baby find out which organs of his body are even and which are odd (such as eyes, ears, hands and feet are even; Head, nose and mouth are singular), and then let the baby find out which clothes are singular and which are even (such as socks, shoes and gloves are even, hats, scarves and belts are singular), or let the baby tell which items in the house are singular and which are even, so as to consolidate the understanding of single and even numbers.
Third, let the baby practice.
1) Counting: Parents put some sweets in a small cloth bag to let the baby feel whether it is odd or even, and then pour it on the table to see if it is correct. Every time the baby touches it right, parents will reward it to arouse the baby's interest in learning.
2) Number plate classification: Parents put together a number of 1- 10 number plates, and let the baby arrange the number plates in two rows according to the single and double numbers.
3) Listen and say even and odd numbers: Parents quote a number, and let the baby immediately answer whether it is odd or even. Countdown refers to counting in the opposite direction to the natural order. Teaching your baby to learn reciprocal can help him master the order of natural numbers from the opposite direction, develop his reverse thinking and help him learn addition and subtraction.
It is not difficult to teach your baby to know odd and even numbers. As long as parents are patient, persistent and methodical, they will certainly let the baby learn well, thus better cultivating his logical thinking ability.
Extended data:
(1) Odd number is another name for positive odd number in mathematics. Mathematically, as opposed to even numbers (positive even numbers), it can be expressed as 2n+ 1 (n is an integer greater than or equal to 0).
(2) Even number is another name for positive even number in mathematics. Mathematically, as opposed to odd numbers (positive odd numbers), it can be expressed as 2n numbers (n is an integer greater than or equal to 1), and even numbers must be divisible by 2. It is worth noting that 0 is not an even number (as stipulated by the International Mathematical Association in 2002 and China in 2004), because 0 is not a positive number.
