The acquisition of mathematical knowledge is inseparable from life, and "mathematics learning is inseparable from life". According to children's psychological needs and the law of education and teaching, if students want to learn easily and master knowledge firmly, only by making mathematics learning based on students' cognitive development level and existing knowledge and experience, coupled with close contact with life, can they really master mathematics knowledge.

Successful teaching experience inspires every teacher. If "pure" mathematical knowledge can be linked with familiar and concrete materials in students' daily life in mathematics teaching, it will be beneficial to concretize and visualize abstract mathematical concepts, facilitate students' understanding and stimulate students' thinking and desire to explore new knowledge.

Because children can participate in experiments by themselves, they will be interested in such classes and study happily. However, it is still difficult to form a fixed concept in your mind after only one or two operations.

That is to say, when measuring with various quantitative containers in class, children will form certain concepts of milliliter, deciliter and liter, but when they don't have these things in front of them, it is difficult for them to grasp them again.

So, when the blackboard appears, "How many deciliters are 3 liters and 5 deciliters?" Children will find it difficult to convert such units.
