Adding hands: first, open your hands, the left hand indicates an addend, and the right hand indicates an addend. For example, if your left hand has three fingers and your right hand has four fingers, let your child count three on the left and four on the right, and you will get 3+4, 1234567, and 3+4=7.
Two-handed subtraction: one hand turns back and the other hand moves forward. The opposite hand represents subtraction and subtraction, and the other hand represents subtraction. For example, the left hand holds out four fingers and the right hand holds out two fingers, so that children can count, and the left hand subtracts the right hand.
Use some tools, such as sticks, things that children are interested in, and some graphics to stimulate children's interest in learning mathematics.

1. It's complicated to make arithmetic easy before it's difficult, but it's hard for children to accept if they learn difficult arithmetic from the beginning. Parents can integrate life into their children's math study.
In this way, letting children unconsciously contact and learn mathematics in life can improve their interest in mathematics and help them understand the importance of mathematics in life.
2. Use decomposition skills to teach children from the beginning of decomposition and combination. At the same time of division, use language to express. Be sure to say it with your mouth. The child who can speak out means that she really has it. Start with less than 5. Let's talk about decomposition 2 first. Remember to put them together after each separation.
3. Remember large numbers and add and subtract decimals. Addition: Remember the large numbers in your mind and count the decimals up, for example, 4+2= remember 4 in your mind, count up two numbers, 5 and 6, and then get the result 4+2=6.
Subtraction: Remember large numbers in your mind, and remember decimals downward, for example, 6-3= 6 in your mind, the number from the bottom, 5, 4, 3, and then get the result 6-3=3.
Parents need to cooperate with each other to add or subtract 30 words within 10 for their babies every day to improve their arithmetic ability. Be careful not to let children count their fingers, develop habits that are difficult to change and cultivate mental arithmetic ability.
4. Some practical things that children need to master. The first thing to remember is that 10 plus a few equals 10.
Example:10+1=1,10+2= 12, until 9, and the second one to remember is1+/kloc-0.
