My method is to do this kind of problem.
At first, parents will give a real example after reading the topic. They will give pocket money, count their fingers and share snacks, especially her favorite things. If the questions are similar, they will usually answer.
Secondly, parents are emotional when they look at the topic, and it is easy for their daughters to follow the example just now.
Slowly, some simple addition and subtraction problems will be done.
The multiplication and division method is abstract, generally taking this as an example. You can take a pile of melon seeds as an example to emphasize whether it has become more or less. When several piles of melon seeds are rubbed together, there must be many, that is, multiplication.
Finally, let your daughter read the topic. At first, you can give her a word. You can make a model. For example, if there are five students, you can take out five sweets and put them on the table. In short, you can show the topic. When she can read the topic emotionally, she will understand.
You can also ask her to repeat it. Generally, children have no consciousness after reading it, but they are literate and don't want to understand the meaning.
This is just a little experience when I was a tutor. I hope it helps you.
