1, the calculated number does not exceed 20, such as 12+7, 18-9, etc.
2. Compare sizes, such as 7+8 and 15, which is bigger?
3. Simple counting problem. For example, there are seven apples in one basket and five apples in the other. Now, the apples in the two baskets should be combined. How many apples are there?
4. Simple number counting problem. For example, there are five stars in one row and three stars in the other row. How many stars are there in these two rows now?
5. Simple arrangement. For example, there are five books to put on three shelves. How many books should be put on each shelf to get all the books on the shelves?
Math problem-solving skills in senior one;
1. Master basic concepts: For the math problems in Grade One, basic concepts such as addition and subtraction and size comparison are usually involved. Therefore, students need to master these basic concepts skillfully in order to solve math problems better.
2, a variety of methods to solve problems: first-year math problems are usually relatively simple, you can use a variety of methods to solve problems. For example, addition and subtraction can be done by various methods, such as direct calculation, rounding to ten, decomposition and so on. For the comparison size, the number axis comparison method and the difference comparison method can be used.
3. Carefully examine the questions: Examining the questions is the key to solving mathematical problems. Students need to carefully examine the questions, understand the background and requirements of the questions, and clarify the ideas and methods of solving the problems.
4. Careful calculation: calculation is the core of solving mathematical problems. Students should master basic calculation methods, such as addition, subtraction, multiplication and division. When calculating, you need to calculate carefully to avoid calculation errors.
5. Be good at summarizing: summarizing is an important way to improve the ability of solving mathematical problems. Students need to be good at summing up the experience of solving problems, finding their own shortcomings and improving them in time.
6. Practice more: Practice more is an effective way to improve the ability of solving math problems. Students can practice different types of questions, deepen their understanding and mastery of mathematical knowledge, and improve the speed and accuracy of solving problems.
