With these two premises, it is easy to improve your grades: 1. Contact two people multiplied by a number (ten questions a day) and get more than ten questions in a week.
2. Practice multiplying two digits by two digits. The method is as above. This step meets the requirements and can basically reach 60 points.
3, to further improve, we must grasp the application problems. On the one hand, parents should be familiar with the little things around them, shopping and traveling, and educate them in life. For example, go to the supermarket to buy food, look at the price, weigh it, and let children learn how to arrange it. Tell your child the speed when you take the bus, tell him how long it will take to clean the destination, and let the child think about how to ask. In this way, I can use my life experience to improve my math ability.
Of course, we should pay attention to the encouragement of children in this process.
That's basically all, and there will be no problem until 3 o'clock above the basic 80 points.
