#2023 Parenting Season#In less than half a year, the children in the kindergarten class will enter the first grade. Because this large class collided with the epidemic, my son's school time was almost equal to the time of listening to classes, which made a lot of learning content very rushed, and some content was even slightly exposed in kindergarten.
In order to make their children more adaptable to learning when they are in the first grade, parents can check the gaps in their children's math learning from these 9 aspects.
First, recognize the numbers 1-100
1. Proficiency in counting
(1) Will count in the order of 1-100: 1, 2, 3, 4, 5...
(2) The number of multiples of 5 intervals: 5, 10, 15, 20...
(3) The number of multiples of 10 intervals: 10, 20, 30, 40...
2. Writing specifications
Develop good digital writing habits, and will occupy the grid according to the writing standard on the field character grid.
2. Singular and even numbers within 20
1. The singular refers to numbers that cannot be paired in pairs: 1, 3, 5, 7, 9, 11, 13, 15, 17, 19
2. Even-numbered numbers refer to numbers that can be paired in pairs: 2, 4, 6, 8, 10, 12, 14, 16, 18, 20

3. Number of neighbors
Adjacent number: A number with a number more than 1 or less 1 is called a neighboring number
For example: 6, 7, 8 The adjacent numbers of 7 are 6 and 8; 12, 13, 14 The adjacent numbers of 13 are 12 and 14.
Fourth, the ratio of size
1. Cognition is in line
Greater than sign>, less than sign<, equal sign=
2. Recipes
Greater, less than, two brothers to go together; The tip in front is less than, and the opening in front is greater than; Two numbers stand in the middle, who rushes and laughs haha.
3. Application
(1) Specific size
9＞6 17＜20 15＝15
When comparing sizes, you also learn to compare deformations. Like 8>2+3 10+5<7+6

(2) Will sort
For example: 9<8<7<6<5
This is the most basic ordering, and there are also things like this that must be learned. For example, sort the numbers 9, 3, 7, 5, 11, 17, and 19 in order from largest to smallest.
5. Decomposition and synthesis within 10
1. Decomposition and synthesis should be carried out in an orderly manner to prevent omissions, and at the same time, children should be guided to observe the numerical rules of decomposition and synthesis.
1. Recipe: the tip of the mountain is the mother, and the remaining two are babies; Mom no longer uses addition, baby doesn't use subtraction.
6. Calculation
1. Main calculation methods
(1) Ten method (addition)
Split decimals, make up large numbers, make up 10, and add the remaining numbers.
(2) Breaking the Ten Law (Subtraction)
Divide the large number, divide the 10, decrease the number, and add the remaining number.
2. Recipes
Make up ten methods: 1919 good friends, 2828 hand in hand, 3737 really intimate, 4646 walking together, 55 into a pair of hands.
Break the ten law: ten minus 9, a few plus 1; A dozen minus 8, a few plus 2; A dozen minus 7, a few plus 3; A dozen minus 6, a few plus 4; A dozen minus 5, a few plus 5.
7. Order, comparison
1. Understand cardinal numbers and ordinal numbers
Know the difference between several and several, know the directionality of ordinals
For example: ▲ ● ■ ★ ♣
(1) From left to right, please circle the 4th pattern with a red color pen;
(2) From right to left, please circle the third pattern with a black color pen;
(3) Please circle the second pattern with a green colored pen.
2. Classification comparison
Compare size, height, length, weight, weight, and quantity, and use the objects in life to cultivate children's mathematical thinking.

8. Know the counter
1. Basic concepts
1 bead on the single position represents 1 one; 1 bead on the ten digits represents 1 ten; Ten ones equals ten
2. Application
For example: (1) 17 is composed of (1) tens and (7) ones;
(2) 20 has (2) tens in it;
(3) The single digit is 2, the ten digit is 6, and this number is (62).
9. Know clocks
1. Basic concepts
(1) There are 12 numbers on the clock face, representing the hour;
(2) There are 60 grids, one grid represents 1 minute;
(3) The long needle is the minute hand, and the short needle is the hour hand.
2. Recipes
The small dial is round and round, and the hour and minute hands run in circles; The minute hand is long, the hour hand is short, the minute hand is fast, the hour hand is slow; The minute hand is 12 long fingers, and the short hand is a few hours; The minute hand is 6 long and long, and the short hand is just a few hours and a half hours later.
When the minute hand points to a number less than 6, the hour hand points closer to the smaller number; When the minute hand points to a number greater than 6, the hour hand points closer to a larger number.
3. Application
For example: (1) the long needle points to 12, and the short needle points to 8, indicating 8 points;
(2) The long needle points to 6, and the short needle points to the middle of 3 and 4, indicating 3:3 and a half.

The above are the mathematical knowledge points of the 9 aspects in the early childhood connection, but it is not enough to master the knowledge points, but also to be able to use and do problems.
My son has been doing Kumon-style education books since middle school, and he has made more than a dozen books. After the first class, he successively did more than a dozen books such as learning and thinking, mathematical thinking training, etc.
If some of the above mathematical knowledge points have not been contacted, or only slightly contacted, you can first do the set of books "10 minutes to accompany the math baby".
"10 minutes to accompany the math baby"
"10 Minutes to Accompany the Math Baby" has a total of 4 books, the content of which covers all the above knowledge points, and many knowledge points are also subdivided.
Whether it is ordinal, singular and even numbers, these common knowledge points, or equal transformation, conservation, finding rules, classification, etc. have special exercises.
After doing this set of books, the child will have a general understanding of the mathematical content of the entire toddler connection, and this set of books is in the form of a story is very suitable for children in the early childhood stage, my son does more questions every time, and there has never been a conflict because of the questions.
