We have to calculate how many rows they can sit in and how many people have no seats. Assuming that the number of seats in each row is A and the number of fourth-grade students is B, according to the topic, we know:
1, a=26 (because there are 26 seats in each row)
2.b= 140 (because there are 140 students in the fourth grade)
What we want to calculate is:
1, the number of rows that can be filled =b÷ a= 140÷26=5+ 10.
2. Remaining population = 10
The calculation result is that the fourth grade can fill 5 rows, and the remaining 10 people have no seats.
Mathematical thinking in primary schools:
1, observation ability: cultivate children's ability to observe the surrounding environment carefully and help them discover mathematical phenomena in daily life. For example, stimulate children's interest in mathematics by observing the shape of leaves, the geometric structure of buildings or the price changes on shopping lists.
2, logical reasoning: teach children how to use logical thinking to solve problems. Cultivate children's ability to ask questions and analyze problems from an early age, and guide children to learn to start from known conditions and gradually establish conclusions. For example, teach children how to solve math problems by comparing sizes and finding rules.
3. Abstract thinking: Help children understand abstract concepts and perform simple operations. Teach the basic principles of addition, subtraction, multiplication and division and guide them to apply these concepts to real life. For example, teach children how to calculate change or allocate pocket money when shopping.
4. Spatial imagination: cultivate children's ability to build three-dimensional spatial models in their brains. Through painting, puzzles and other activities, help children learn to observe the shape, direction and position of objects, and then understand the concept of space.
5. Mathematical formulas and symbols: help children understand and remember mathematical formulas and symbols, such as the basic formulas of addition, subtraction, multiplication and division, and the meanings and application methods of mathematical symbols such as fractions, decimals and percentages.
6. Problem-solving strategies: Encourage children to master problem-solving methods and skills. For example, try different methods to solve problems, find rules and shortcuts, and check the correctness of the answers.
