Decomposition is a method often used in mathematical application problems or other formulas. Learning decomposition method is of great significance for future math exams and learning.
First, do your homework with your children. When learning decomposition method, parents should try their best to guide their children and answer them in time when they don't understand calculation.
Second, show it to the children on the blackboard. If conditions permit, use decomposition method to show children the specific steps of decomposition method on the blackboard, so that children can learn decomposition method intuitively.
Third, buy video tutorials for children. Video tutorial is an important tool for learning. If economic conditions permit, you can buy video tutorials for your children.
1, the kindergarten class will learn the decomposition within 10. You only need to find ten sticks or 10 of the same thing.
2. First of all, from the decomposition of 2, let children count the number of things with two identical things, and then separate them. Children can clearly and intuitively see that two things can be divided into 1 and 1, which means that 2 can be decomposed into 1 and 1, and then tell them 1 and 60/in turn. Putting it out in kind can better help children understand.
3. Next is 3. Similarly, take out three items, put one on one side and the rest on the other, and you can intuitively see one on one side and two on the other. So 3 can be decomposed into 1 and 2, and 1 and 2 form 3, 1+2=3. Inverted 3 is first broken down into two, and then the rest is put on the other side, which is the second decomposition method of 3. 3 can also be decomposed into 2 and 1, 2 and 1 to form 3,2+1= 3.
Mathematics teaching methods adopted include: inspiration, explanation, conversation, practice, discussion, demonstration, practice, observation and review. Among them, inspiration, explanation, dialogue and practice are used more. At present, the experimental mathematics teaching methods at home and abroad include: discovery, research, self-study guidance, program teaching, optimization teaching, algorithm teaching, "reading, discussing, speaking and practicing" and so on.
