Who is more and who is less in the second grade?

In the second grade mathematics, who fills in the blanks more than who, who fills in the blanks less than who, mainly examines the comparison method, understanding ability and application ability of numbers.

For example, a family of three went to the supermarket to buy food. Dad bought vegetables at 10 yuan, mom bought radishes at 1 1 yuan, and sister bought beans at 12 yuan. My sister spent (1) yuan more than my mother, and my father spent (1) yuan less than my mother. On the other hand, mom uses (1) yuan more than dad. Such mathematical information is often encountered in daily life.

Dobby's skills are not as good as those of grade two.

Law: large numbers are calculated by addition and decimals by subtraction. Solve a few more and solve a few less, and subtraction can solve them all. Skills: There are fewer math problems than Dobby, and all the big ones use drawing. Drawing is one of the best ways to help children understand problems. In the process of teaching children, parents can help them better understand the size by drawing line segments, shapes and even pictograms.

When talking about this kind of problem, you can tell your child with practical examples.

For example, a mother has five apples and a child has two apples. How many apples does a mother have more than a child? How many apples does the child have less than the mother?

When talking about this topic, mothers can ask their children to count their apples and ask them questions to see who is more than who. Who is less than who.

Mathematics is a highly systematic subject, and its contents are closely related. As far as the content taught by school teachers is concerned, the previous content is often the necessary basis for later learning. If you don't learn well in the front, it will definitely affect the learning of knowledge in the back.
