The formula is correct, the calculation is correct, the unit is reasonable, and the answer is complete.

If the formula is correct and the calculation is incorrect, points will be deducted according to the score proportion. For example, if 5 points are incorrect 1 point, if 6 points are incorrect, 2 points will be deducted. If it is a multi-step application problem, when calculating step by step, the result is wrong, and only the corresponding steps are graded according to the steps.

If the title is copied wrong and the method is correct, you won't score.

Incorrect or missing 0.5 points/unit.

0.5 points will be deducted for incomplete answers.

When solving the equation application problem, there must be a solution and a design, otherwise 0.5 points will be deducted.

For children in primary schools, the most important thing in mathematics learning is to exercise their calculation ability, train and improve the accuracy and speed of calculation. Children's computing ability, especially their oral expression ability, also reflects their reaction ability to a certain extent, which is very helpful to improve students' thinking ability.

As the focus of primary school mathematics learning, application problems are even more difficult. Application problem is an important question to cultivate students' logical thinking ability and calculation ability in primary school, and it is also the basis for senior three students to learn in the future.
