The embodiment of the sense of quantity in primary school mathematics textbooks is the visual or tactile effect on size, quantity, length, thickness, Fiona Fang, thickness, weight and speed.
In mathematics, the term sense of quantity refers to the perceptual knowledge of the size, quantity, length, thickness, Fiona Fang, thickness, weight and speed of an object through vision or touch. In primary school mathematics teaching, it is very important for students to form perceptual cognition intuitively after multi-sensory contact with objects, so as to cultivate pupils' "sense of quantity", which can effectively promote students' core literacy in mathematics.
Therefore, in teaching, teachers can design related mathematics activities in combination with the content of teaching materials, so that students can establish quantitative awareness in practice. Teachers should guide students to establish accurate quantitative consciousness. As long as such a "sense of quantity" is established, students' grasp of mathematical concepts will be more accurate and clear.
Why do primary school mathematics textbooks emphasize the concept of quantity?
From the foreign curriculum standards, we can see that many countries attach great importance to measurement, and some do not explicitly put forward the word sense of quantity, but from the perspective of curriculum design and arrangement in these countries, they all attach great importance to measurement and infiltrate the cultivation of sense of quantity into textbooks. There are four areas of primary school mathematics in China: number and algebra, shape and geometry, statistics and probability, synthesis and practice.
There is no content in the field of "measurement" or "measurement". Because we didn't pay enough attention to measurement in the past, we added "sense of quantity" to the performance of core literacy when the curriculum standards were revised, and added this word to emphasize measurement.
Sense of quantity refers to the visual or tactile sense of the scale, degree and speed of various objects, and the perceptual knowledge of the size, quantity, length, thickness, Fiona Fang, thickness, weight, speed and compactness of objects.
