Matematik i folkeskole er ikke bare tal. Det er fundamentet, som hele logikken, ingeniørvidenskab og endda kunstig intelligens står på. Hvis et barn ikke forstår, hvad et tal er, eller ikke lærer tabellen af multiplikation i tredje klasse, vil det have ondt hele livet. Men hvordan gør man, så barnet ikke hader matematik, men elsker den? Lad os finde ud af det med eksempler, spil og skrækker fra sovjetiske lærebøger.

What is studied in 1-4 classes

Programmet for folkeskolematematik er standard. I første klasse — tal, tælling op til 10, addition og subtraktion op til dette årti. Opgaver med ét trin. I anden klasse — tælling op til 100, overgangen til ti, tabellen af multiplikation på 2-5, opgaver med to trin, begreberne "omkreds" og "areal" af enkle figurer.

I tredje klasse — hele tabellen af multiplikation, division med rest, multiplikation og division af fler cifrede tal med et cifret tal, brøker (grundlæggende begreber), enheder af tid, længde, masse, hastighed. I fjerde klasse — fler cifrede tal (op til millioner), handlinger med dem, ligninger, brøker (sammenligning, addition og subtraktion med ens zener), procent (begyndelse), opgaver om bevægelse i efterfølgelse og mod.

Det ser ud til, at det ikke er meget. Men det er i folkeskolen, at algoritmisk tænkning lægges. Hvis barnet ikke forstår, hvordan multiplikation fungerer, vil det aldrig forstå, hvordan integral fungerer. Derfor kan man ikke ignorere "Det er bare simpelt".

Why do children hate math in school

It's not the children who hate. Children love to count when it's about candy or toys. They hate the method of presentation. Boring examples in columns where you have to rewrite 30 similar actions. A teacher with a strict voice who scolds for a mistake. Fear of "not understanding". Perfect storm.

The second reason is parents who pressure. "You must solve it on five," "look at your neighbor, she managed, but you didn't." The child begins to associate mathematics with danger and shame. The brain blocks logic to protect itself.

The third reason is the lack of visual aids. The textbook says: "3 + 5 = 8". But what are these numbers? Three apples and five pears are already more interesting. But teachers often save time on pictures.

The fourth reason is the transition to a new place in second grade. This is a stumbling block. The child does not understand why 27 + 5 = 32. Instead of explaining on counting sticks, teachers force them to just memorize the algorithm. And children become dumber.

How to explain addition and subtraction with a carry

The secret is in counting with sticks or buttons. Take 27 buttons. Count 10, tie a rubber band — this is a ten. Tie another 10 — the second ten. There are 7 buttons left. Now add 5 buttons. Add 3 to the 7 buttons to make another ten. Now we have 3 tens and a remainder of 4 buttons. 27+5=32. The child sees. Understands. Remembers forever.

You can use a mind map: draw a line from 0 to 100. Go right on 5 steps from 27. 28, 29, 30, 31, 32. Then train without a drawing.

For subtraction — reverse counting. 32 - 5 = 27. Go left on 5 steps from 32. 31, 30, 29, 28, 27.

The main thing is not to rush. One topic can take a week. Better slowly but with understanding than quickly with memorization.

Times table: how to learn without tears

Pythagoras' table is a curse of primary school. But there are ways to make it easier. First — visualization. Draw a square 10x10. Write the product in each cell. The child sees symmetry. For example, 5x4 and 4x5 are the same, which reduces the amount of memorization by half.

Second — poems. "Three on three — nine, this must be checked by everyone." "Twice two — four, this is known in the whole world." You can come up with your own.

Third — cards. On one side, the example "3x4", on the other side the answer is 12. The child checks himself. Game: who collects 10 cards faster.

Fourth — songs. There are plenty of times tables in rap on YouTube. The child absorbs rhythmically.

Fifth — object counting. 3x4 is three times taking four candies. The child counts. Tasty and clear.

Important: do not learn the whole table at once, but in blocks. First on 2, then on 3, then on 4. A break of one day to two between blocks. And repetition: mix old examples with new ones.

Fractions in primary school: when to start

In first grade, fractions are not mentioned. But in second-third grade, the concept of half (1/2) and a quarter (1/4) can be introduced on a pizza or cake. Cut the circle into 2 equal parts — each half. On 4 — a quarter. The child understands immediately.

In fourth grade, fractions with different denominators are introduced for comparison. Again, in practice: two-thirds or three-quarters of a cake — which is bigger? Cut circles with different denominators, overlay transparent films. You can see with your eyes.

Addition of fractions with the same denominators is the addition of pieces of the same cake. 1/4 + 2/4 = 3/4. Easy. For different denominators in fourth grade, only the simplest cases (1/2+1/4=3/4) are given with the help of a drawing.

Do not require fourth graders to abstractly reduce to a common denominator. This will kill love.

Logic problems: how to develop thinking

Mathematics in primary school is not just counting, but also logic. Problems like "Three sparrows were sitting on one branch, two came, then one flew away. How many are left?" develop the sequence of actions. It's better to have problems with extra data so that the child learns to filter out unnecessary. "There are 3 apples, 2 pears, and 1 banana in the vase. Natasha ate 2 apples. How many fruits are left?" — extra about pears and bananas.

Logic puzzles with a star: "How many ends are there on 3 and a half sticks?". Or "Ten sticks are on the table. Two boys take turns taking 1 or 2 sticks. Who will win?". This is already strategy.

The best way is chess, checkers, sudoku for children. Do not impose, but play together. A math circle is also good, but not before 8 years old.

Typical mistakes of parents and teachers

Mistake number one: scream "You don't understand? It's elementary!". For a child, it's not elementary. His brain has not yet formed neural connections. Your "elementary" is the result of 30 years of practice.

Mistake number two: forcing to solve many similar examples. Better 5 times with explanation than 50 automatically. Automation will come later.

Mistake number three: comparing with others. "Peter has already solved it, but you haven't." Compare only with yourself: "Yesterday you made a mistake in this, but today — not, good job."

Mistake number four: ignoring mistakes. A mistake is not a failure, but a hint where there is a gap. Analyze the mistake together. Ask: "What do you think, why did it turn out to be 7, not 8? Let's recalculate."

Mistake number five: pressuring time. "Solve it in 5 minutes." Anxiety kills thinking processes. Give as much as needed, but don't drag on.

Mistake number six: making math a routine. Don't do examples after school if the child is tired. Better to play "shop" (where change has to be counted). Or weigh fruits and compare the weight.

Games and applications for math

On paper: "Battle ship" with coordinates (develops the coordinate system). "Tanks" on a grid (movement along vectors). "Mathematical bingo" — a number falls out, you close the answer.

Outside: count cars, clouds, steps. Measure distance with steps. Compare the height of trees. Weigh stones on homemade scales.

In the kitchen: recipes — half a cup of flour, a quarter of a teaspoon of salt. Portion: you need to treat 5 guests, and 15 cookies — how many for each?

Applications (without links): "Mathematics and Numbers for Children", "Counting", "Times Table in Games". The main thing is to dose it, no more than 20 minutes a day.

Important: no applications before bedtime. The brain should switch.

What to do if a child is mathematically unable

True inability to do mathematics (dyscalculia) occurs in 3-7 percent of children. It's not laziness, it's a brain feature. Symptoms: cannot understand that 4 is greater than 3, even if shown buttons. Confuses numbers 6 and 9, 2 and 5 constantly. Cannot count objects up to 10, even counting on fingers. Cannot memorize the multiplication table, despite long training.

If this is your case, go to a neuropsychologist and a child psychiatrist. Dyscalculia cannot be cured, but it can be corrected. The child will be given a lenient program, possibly exempted from the second foreign language. Do not blame yourself and him. It's not your fault. It's a diagnosis.

But more often "inability" is the result of intimidation or bad teaching. Change teachers, change the approach, take lessons with a tutor who uses games. The result may surprise you.

Mathematics and life: why is it necessary for a child

When he grows up, he will count his salary, taxes, discounts in stores. To take a loan or not. Compare prices per kilogram. Understand if the "two for the price of one" promotion is beneficial. But this is not the main thing. Mathematics teaches structured thinking. Do not panic in front of a difficult task, but break it down into parts. Look for patterns. Check yourself. These are skills for life.

Therefore, do not say "math is boring". Say "math is magic that helps predict the future". And the child will believe it. And love it.
