Do practical things, practice constantly, and understand from practice. I am still like this, because it is said that mathematics is the gymnastics of thinking, and understanding the meaning of addition and subtraction can really exercise children's thinking.
Addition: in fact, it is to add two sets together to make one set.
Subtraction: Divide a set into two parts.
Children really understand the meaning of addition and subtraction, not knowing the problem, but understanding the relationship between addition and subtraction. For example, 4 apples can be divided into 1 and 3 apples and vice versa. Meanwhile, 1 and 3 apples (or 3 apples and 1 apple) add up to 4 apples. That is to say: teaching children to start from the decomposition and combination, while expressing in words, must be said with their mouths, and the child who can say it shows that she really has mastered it. Let's talk about decomposition 2 first. Remember to put them together after each separation.
Learn addition and subtraction within ten at these points: 1.
Easy first, then difficult. Let's talk about addition and subtraction within ten. It can be combined with objects that can be expressed by quantitative concepts in life. Such as apples, oranges, lychees, tomatoes, mangoes, etc. , can improve children's interest and let him know the important role of learning mathematics in life. 2.
Consolidate the results Parents should use all available time to ask questions to their children. As long as you have free time, you can ask questions and speak quickly, which will give your child a sense of urgency and exercise his habit of thinking quickly and improving efficiency. Parents can say 3+2, 4-3, 4-2, etc. As long as the child answers correctly, he should be praised, "Great", "Great" and "My child is really smart". Addition and subtraction within ten minutes should make him particularly skilled. Not too fast, step by step, the best effect. 3.
The addition and subtraction in ten counseling skills, once again, must make children extremely skilled. Achieve the effect of blurting out. Don't worry. It is necessary to tell children that addition and subtraction are complementary, especially within ten minutes, which helps children understand. 4.
Timing strategy should allow children to do exercises regularly, and also allow children to do and finish problems, so that children can feel a little progress and improve their fun in practice. Reward overtime, please continue to refuel next time if you are slow!
I hope these arrangements can help you!
