Error-prone problems in second-grade mathematics
For example, 1, queue the digital dolls: 5, 6, 10, 3, 20, 17, which can be arranged in descending order or descending order.
Pay attention to write a number when doing the problem, cross out one, don't be heavy, don't miss it. )
2, take any two numbers within 20, and you can use who is bigger than who or who is stronger than who.
For example, 16 is greater than 15, which means16 >; 15
9 is less than 13, indicating 9.
3、? Than? Usage of words
Do you see it? Than? Who's behind this? If it is greater than a few, add1to the number; If it is smaller, you have to subtract 1 from the number.
For example, the number 2 less than 5 is (3), and the number 3 greater than 4 is (7).
3. What number and what number?
△▲▲★△☆☆△△△▲★★★☆★
Look at the picture. How many numbers are there? (16 number) What's the number on the left? What's the number on the right? Circle the left three; Circle the second one on the right.
(When reviewing this kind of knowledge, we should distinguish between left and right and determine the direction at the same time; Know the difference between a few and a few. )
4. Adjacent numbers
2 is preceded by 1 and followed by 3. 2 plus 1 equals 3, 3 minus 1 equals 2. The numbers adjacent to 2 are 1 and 3.
3 is preceded by 2, and 3 is followed by 4. If you add 1 to 3, it is 4. If you divide 4 by 1, it is 3, and the numbers adjacent to 3 are 2 and 4.
