1, start with a unit, for example: 1+2=3, 5+4=9, 8+7= 15, and then inspire children. What can 15 be equal to? If the child answers correctly 15 = 1.5, it means that the child knows the unit conversion. If not, tell the child that 10 points = 1 angle, and then give 20 points =(2) angle and 35 points =(3) angle. Similarly, the conversion between angles and elements is the same, for example, 5 angles +8 angles = 13 angles, then what can 13 angles be equal to? I think children will think of 13 angle = 1 yuan 3 angle and tell them 10 angle = 1 yuan. Similarly, some questions are 20 angles =(2) yuan and 88 angles =(8) angles.

2. Change small denominations into large denominations, and then let the children change them in reverse, for example, six triangles = (hexagon), eight dollars = (eighty) cents, that is, one dollar equals ten, one quarter equals (fifteen) cents, and so on.

3. For the conversion of points and elements, you can first convert elements into angles, and then convert angles into components. For example, ask the child 1 angle = 10 score, 10 angle = (? ) Then ask the children to answer 1 yuan = 100 points, some questions 5 yuan 6 Angle =560 points and so on.

It is not intuitive for children to learn the conversion between units only by writing. They can start by knowing the currency, and let them know the current denomination of RMB: 100 yuan, 50 yuan, 20 yuan, 10 yuan, 5 yuan, 2 yuan, 1 yuan, 5 cents, 2 cents, 1 corner, 5 points. If parents have time, they can play some games with their children to buy and sell things, which can not only promote parent-child relationship, but also strengthen understanding. Why not do this? There are more than one way to exchange money, which can exercise children's thinking and calculation ability. For example, they use 10 yuan to buy goods from 2 yuan, and the money they get back can be 8 bills 1 yuan, or 1 5 yuan. Then 1 5 yuan, 1 2 yuan, 1 0 yuan. Ask your child which way to get the most or least numbers. Practice more and the child will master it.
