Step 1: Understand the problem correctly.
After seeing the question first, we should make clear the content of the question, the type and specific value of the answer, and then determine the method of answering. For example, by reflecting the mathematical meaning through graphics, we can understand and answer questions more vividly.
Step 2: Correct selection of relations (addition, subtraction, multiplication and division) and symbols.
Combined with graphics, judge the situation of addition, subtraction, multiplication and division, and choose the correct symbol.
I used to worry about my children's study. I can't learn math in grade one, and I don't know how to guide my children's study. Until I saw a class two months ago, after a period of time, my grades have improved a lot, and my children's interest in learning and grades have improved. As a parent, I finally breathed a sigh of relief and my children were much more active!
Step 3: Column combination
After seeing the topic, list the known values and write a line. You should remember that formulation helps to find out the solution to the problem accurately and plan the way. Only after formulation can calculation errors be prevented.
Step 4: Be careful with the calculation of data.
If you do mental arithmetic, you should first make an approximate calculation with an accuracy rate above 96%, and check it in case of uncertainty. The heavyweight knowledge of primary school mathematics should not be underestimated.
In a word, how to explain the diagram problems in first-grade mathematics? Explaining the charting problems of first-year mathematics needs to follow certain methods and principles, so that students can better understand the problems and find ways to solve them.
Through the teaching of this kind of questions, we can not only improve students' mathematical literacy, but also exercise their thinking ability and creativity, and lay a solid foundation for their future study.
The main purpose of looking at pictures is to help children associate observed things with numbers and form certain memories and rules. By observing the data in graphs and tables, children can gradually learn to understand and apply basic mathematical operations.
