A dollar is ten cents, so you can't go wrong.
Ten cents and so on. , it must be true.
Equal to one yuan, you will earn more money when you grow up.
Jiao Yuan is divided into three brothers, Brother Yuan Joule and Brother Yi Fen.
It is easy to convert between the two, plus 0 MINUS 0.
Big and small plus a 0, small and big minus a 0.
If the eldest brother becomes the third brother, two zeros should be added at the back.
If the third brother wants to be the eldest brother, he is the only one left.
Explain the concept of Jiao Yuanfen to children.
Parents can teach their children from simple to complex, starting from a single unit, such as 1 +2 =3, 5 +4 =9, and the conversion between "angle" and "yuan" can also be done in the same way. For example, you can ask your child how much 14 is equal to 65438+. The conversion of "points" and "angles" can also be done in this way, or the children can do it in reverse, so that the children will be familiar with Jiao Yuan points after several times.
Practical application of meta-angle knowledge
On weekends, parents can take their children to the supermarket to buy things, and consciously let them use what they have learned to know the price of goods and see if they have mastered the conversion of yuan and jiao. Or you can take your children to the second-hand market and sell clothes and things they don't wear. The children will calculate the price and, accompanied by their parents, see their hands-on ability. Parents can also give their children some simple questions about the conversion of yuan and cents, or ask some questions about the calculation of small change in buying and selling things, and teach them through entertaining.
