Children's songs about how to break ten methods in primary school mathematics.

It is necessary to learn mathematics well, do more problems and be familiar with the problem-solving ideas of various types of questions. At the beginning, we should start with the basic problems, take the exercises in the textbook as the standard, lay a good foundation repeatedly, and then find some extracurricular exercises to help broaden our thinking, improve our ability to analyze and solve problems, and master the general rules of solving problems. The following is a children's song I compiled for you, which is about the ten-point method and the ten-point method in primary school mathematics. I hope it helps you. Welcome to read the reference study!

Collect ten songs

19 19 years of good friends,

Hand in hand,

3737 is so close,

Let's go together, four, four, six, six.

Make a pair of hands in half.

Look at large numbers and divide them into decimals.

Made ten, plus the rest.

Remember large numbers in your mind and decimals in your hand.

One plus nine, ten tadpoles,

Two plus eight, ten old ducks,

Three plus seven, ten old hens,

Four plus six, ten golden monkeys,

Five plus five, ten big tigers.

See 9 and think of 1,

See 8, think of 2,

Seeing 7 and thinking of 3,

See 6, think of 4.

See Osuka decimal,

Switch these two figures first.

1, children should remember "9 to 1", "8 to 2", "7 to 3", "6 to 4" and "5 to 5".

2. The method of making up ten is simple and easy, and the thinking process includes "looking at large numbers, dividing by two (except decimals), dividing by three and adding by four".

3. Look at large numbers, divide them into decimals, make up ten, and add the remainder.

Abdication subtraction

1, abdication subtraction should be kept in mind, starting from the unit;

2, who is not enough to retreat, the standard plus ten does not forget;

3. If the interval is 1, it is best to remember that 0 changes to 10.

Successive abdication subtraction

1, see 0, go ahead and see which one has it;

2. borrow it back. 0 is a bit like 9.

1. Teaching methods of the second grade of primary school mathematics and four methods of mathematical calculation of the second grade.

2. Primary school math homework review set

3. Primary school students' math homework correction comments

4. Incentive evaluation of primary school math homework
