There are usually three combination methods for solving regular problems by numbers, namely, singular combination, double combination and mixed combination of singular and double numbers. The problem-solving strategies of different types of questions are the same.
Mainly teach children to observe the relationship between two adjacent numbers, use addition or subtraction to get numbers, try to let children find the law of numbers themselves, and then solve problems. The topic of graphic pattern discovery can usually be divided into two types: single graphic composition type and multi-graphic composition type, which teaches children to discover the changing trend of graphic quantity and guides them to discover the changing law of graphic quantity.
How to learn mathematics in the first grade
It is very important to define the goal of mathematics learning (not in grade, but in the whole primary school and even the basic education stage). Where the goal is, it often determines what kind of means and direction we will take. If the goal is clear, it will not be taken away by other factors.
For most people, primary school mathematics learning often has several utilitarian goals: getting into key middle schools and universities and getting high marks. Those who are ambitious may want to train their children to achieve something in related fields. These are all realistic, but when we set goals, we should not aim at these utilitarian goals, but return to the essence of mathematics to look at the problem.
Not aiming does not mean that there is no such possibility in the future. On the contrary, when we return to the essence of the subject, we can best protect and mobilize children's learning enthusiasm and various possibilities, and it is also the best way to achieve the above utilitarian goals.
