The lower grades focus on understanding objects and figures, which must be catered to. The problem with our mathematics is that it is too boring and monotonous, and it will always be thousands of problems by mouth. Although calculation accounts for most of the learning content, mathematical thinking must be comprehensive and you can't practice calculation too much. Even if you practice calculation, you should try different forms, such as the following topics and points as the elements of calculation. At the same time, cultivate the ability of calculation and observation.
② Cultivation of observation ability
Thinking training is not about doing difficult problems, but focusing on children's thinking process. Understanding a kind of topic is more effective than large-scale brushing, and the goal of understanding is to use it. Children of this age are not very good at writing, so they should be exposed to some interesting and enlightening topics. I pay special attention to the cultivation of observation in my column, which is equivalent to reading, reviewing and finding keywords in senior grades. For example, the following topic types examine children's observation ability and order understanding ability.
③ Logical reasoning ability
This is the embodiment of the comprehensive strength of mathematics. After observation, analysis, problem solving, comparison and reflection, the correct answer will be obtained. The thinking process will be multi-step and complicated, such as graphic calculation, filling in numbers and drawing. Because the thinking method is comprehensive, it is a good material to cultivate a variety of thinking. For example, the following topic requires not only observation and thinking, but also learning to sum up general laws and some divergent thinking.
④ Hands-on operation ability
Don't neglect playing, jigsaw puzzles, Sudoku and Tangram, all of which need to be considered. Many children with good grades in mathematics in senior grades love to play these puzzle games in junior grades. I think junior three children should learn mathematics and enjoy the process of thinking in painting, puzzle games and practical activities.
For example, Tangram is a good cognitive teaching aid for graphic combination. How many different shapes can 4 and 5 form? Sometimes parents need to play with their children, so that they can interact with each other and enjoy math together. Mathematics textbooks are everywhere, and the key is to be curious about mathematics.
