1. For solving problems involving multi-step calculation, except for a few special questions, it is basically not to grade step by step, but to analyze whether the students' overall problem-solving ideas are correct. Therefore, teachers should not rigidly stipulate that all students should be listed step by step in order to improve the scoring rate, which will reduce the thinking level of some students with strong ability. Students should choose their own methods independently.

2. Problem-solving focuses on examining students' problem-solving strategies and ideas, so the proportion of calculating scores in problem-solving topics is small. For example, for a 5-point question, if the formula is correct, but the calculation result is wrong, then only 1 point will be deducted (no matter how many times it is wrong, only 1 point will be deducted). )

3. Be sure to pay special attention to the unit name and answer of the calculation result.

First of all, subtract 0.5 points from omitting the company name, and subtract 0.5 points from the incomplete answer. For example: "Is 28 yuan enough to buy these goods?" Such a question, if the students' final answer is "enough" or "not enough", is an incomplete answer, and 0.5 points will be deducted. If students write the name of the unit wrong, they should reduce their scores as appropriate. In addition, the company name must be written in brackets.

Second, if the answer is wrong or you don't write the answer, depending on the content characteristics of the question, you will lose half of the total score of the question, or you won't get any score. For example: "Is 28 yuan enough to buy these goods?" For such a topic, if the correct answer should be "28 yuan can buy these goods", but the students wrote "28 yuan can't buy these goods", even if the students' formulation and calculation are completely correct, they can only get zero or half points; If the students' formulas and calculation results are correct, but they don't write the answer of "28 yuan can buy these goods" or "28 yuan can't buy these goods", it means that the question is inconclusive, so if you don't score, you won't get half a point.
