Practice? Take three steps and jump twice? Or? Jump after two steps? Change in 2 and 3 first, and change in 4 after proficiency.
Music rhythm, for example, when playing four-beat music, take three steps to jump, practice several steps first, and then practice in tune. If several children play together, the circle can be expanded. Adults and children jump to the right while counting. When a piece of music ends, everyone jumps to the left while counting.
Second, remember the phone number.
You can memorize the first four digits and then add up the last four digits.
Third, arrange the numbers
You can cut the numbers on the calendar one by one, or you can use a digital card to let the baby recite them slowly in order and arrange them in a row. If you put it wrong, you have to take it off again and again, make it up, and put it again and again. Adults can record time and score. It may take more than ten minutes at first, but then it becomes a few minutes.
Fourth, about the integral?
If you count from the left, put 1 on the left, 2 on the right of 1, 3 on the right of 2, and vice versa. Learning to divide left and right is the most basic sense of orientation, which provides convenience for learning numbers in the future.
Five, look at the clock
A 2-year-old child will look at the position of two pointers and relate them to his own life. The key is to have a regular family life.
Six, beading count
You can ask for several beads, such as wearing a red one and two white ones at intervals. Or wear red, black and white, and so on.
Seven or ten digits
Put 10 first, take out 0 at zero, put 1 read 1, take out1,put 2 read 12 and put 20. Until 50. Adults randomly pick up two numbers and put them together, such as 47. Please read them out and practice more. Until 100.
8. Compare which box has more building blocks.
Piece by piece doesn't necessarily mean that a big box is filled with more. If each piece is big, it can hold less.
Nine, taller than who?
Ten, learn to write numbers
At the age of two, he can write 1, draw a circle and write three numbers, namely 0- 1-8. When I am two and a half years old, I will draw a turn, first a pure turn, such as 3 and 2. Practice more, learn to turn sharp corners, learn to write 7 and 4, want to write 5, but don't like it. Baby writing often happens when drawing. For example, writing 3 is often found by adults when painting birds flying. Tell him to write 3 vertically, and sometimes draw a small sharp corner when drawing. Adults immediately encouraged him to say? Isn't this 7? When the baby is happy, he will write more and learn more. Seize the opportunity by accident. Review the next day.
XI。 Winning size
It is difficult for the baby to understand why 2 is bigger than 1 and 3 is bigger than 2, because all the words on the card are the same size. The most intuitive way is to play a game of winning size with a set of bowls. Whoever takes the big one will buckle the other one, because there are numbers at the bottom of the bowl, and the baby can see clearly that it is 5 buckles and 3 buckles, so the buckled couple can't play any more. The baby gradually sees the sizes and bases of 9 buttons, 8 buttons and 7 bowls and gradually remembers them. After playing, you can use cards instead, even poker.
Twelve. How many can I take?
Around the age of 3, the baby can hold up to 6 hands at a time and can play addition and subtraction games. You can take as many as you want and ask how many are left. Just put them in 1-2 and count a few * * *. It's basically no problem to add or subtract within 5. You can add or subtract more than 8.
Thirteen. combine
Red, blue, round and square, whatever you say.
Fourteen, listen to the number of buttons
In addition to pressing the phone, you can also draw a big circle as a button for your baby to practice with his feet. The arrangement of circles should be the same as the arrangement of mobile phone buttons.
Fifteen, fifty-fifty
Practice paper-cutting: Fold both sides of a square piece of paper in half, align the edges, press the edges of the paper straight, and then cut it into two rectangles with a knife. Then fold the short side of the rectangular paper in half and cut it into small squares.
Use another square piece of paper, align the two corners, press the edge of the paper and cut it into two triangles. Then align the two acute angles and cut them into two small triangles.
A circle, cut into two semicircles, and then cut into a quarter circle.
A square piece of paper is first cut into a rectangle by folding the edge. Adults fold the two upper long sides in half, draw four connecting lines from the midpoint of the long side to the short side with a ruler, and cut them into diamonds. Please close the acute angle of the diamond, align it, cut it and divide it into two regular triangles. You can also cut the two bottoms of a triangle into two triangles. The best way for a baby to learn to split the paper in two is to align the opposite side or diagonal line, hold down the edge of the paper, cut it with a knife and divide it into two equal halves.
Sixteen, put ten
Adult cardboard is cut into six strips with the same length, and 5 and 5 are marked in half from the middle; The other intercepts 2/5 of the short bar and divides it into 1/7 and the other 1/3. Intercept 3/5 of the short pole, divide it into 8 and divide it into 2. 1/5 of the truncated short rod is 1, and the other is 9. The last one, as long as the other two, is 10, packed in cartons. Let the baby combine every two pieces into a length of 10 and put them neatly in the paper box. At first, the baby just practiced alignment, but after several times, he remembered that the two lines marked with 5 together are equivalent to 10, and that 6 and 4 can be aligned to 10, 7 and 3, 8 and 2, 9 and 1 can all be aligned to 10. Let the baby learn the combination of 10 by swinging it. Be sure to play after the baby completely distinguishes the number of 10, otherwise you won't remember the number, and you will lose the role of practicing the combination of 10 just by practicing the length of the pendulum.
Seventeen. Comparison length
18. Compare other things
In addition, if there is too much rice, let the baby guess whether there is too much left or a bowl can hold too much. Guess first and then put the rice in the bowl to see if the baby is right. If you guess often, you will become more and more accurate. Estimates are also a matter of numbers, people say? Know fairly well? It means accurate measurement.
Nineteen. Draw dots, lines and circles
If you order sesame seeds in the circle, don't order them outside, or go online or offline.
Twenty, turn left or right?
For example, going home is the opposite of going back.
Twenty-one, back number and points
Counter and abacus are good for children to practice this. Japanese abacus with beads on the top row is the best. When counting to 5, move the upper row of beads and the lower row of 4 beads; When you count to 10, dial one on the left to return the beads. When you count to 20, dial 2 on the left, and you can know what you are counting at any time. The right to use hands, brain and mouth. The abacus is vivid, which facilitates the synchronization of logical thinking and visual thinking.
Twenty-two, measuring water and sand
Measure two bowls of water with the smallest bowl 1 bowl, and pour it into the No.3 bowl; Then pour two bowls of water from No.3 into No.5, both of which are just filled. If 1 is used, how many bowls of water must be measured to fill No.5? Let the baby try first and then answer. Then shovel sand with 1, scrape the bowl mouth flat, then pour it into No.3 to see how many bowls can be filled, scrape it flat and pour it into No.5, then shovel a bowl flat and pour it into No.5 to see if it is full or high. Let the baby try a small bowl and scoop the sand directly into No.5, depending on how many bowls are needed. This game can let the baby learn to measure water, sand and other substances with no fixed shape in a bowl, and learn how to compare with the capacity.
Twenty-three, spell 1/2, 1/3, 1/4.
Make cardboard into four circles, four squares and four triangles. Leave each shape as a whole and divide the rest into 1/2, 1/3 and 1/4. Take out the pieces and let the baby put the shapes together by himself. When the baby picks up a semicircle, a semicircle, a semicircle and a semicircle, tell him that this is half and that is 1/2. When you pick up the circle of 1/3, the rectangle of 1/3 and the triangle of 1/3, tell him that it is 1/3, and three pieces need to be put together. 1/2, 1/3, 1/4 will leave a deep impression on the baby's mind. Whenever you pick up any piece, you know that it is only a small part of the shape.
Twenty-four, classification
A. apples, pears, peaches, tables and grapefruit;
B. Vests, hats, dolls, sweaters and coats;
C. Knives, scissors, melon seeds, clips and spoons;
Trains, trucks, ambulances, fire engines and windmills;
E. eggs, duck eggs, goose eggs, quail eggs and fried eggs? .
Classification originally belongs to the cognitive category, but the thinking method of analysis and synthesis is similar to the application problem in arithmetic. Although I can't do arithmetic application problems before the age of 3, it is very helpful to learn to analyze and synthesize.
25, bearing
Puzzle. Puzzles are not arithmetic, but an accurate sense of orientation is very helpful for learning the geometry and triangles of image thinking in the future.
