The position and direction of the first unit

1, eight directions: east, south, west, north, southeast, northeast, southwest and northwest.

2.① Relative (east and west), (south and north), (southeast-northwest) and (southwest-northeast).

(2) know who is the standard to judge the position.

③ Understanding position is relative, not absolute.

3. Maps are usually drawn by (upper north, lower south, left west and right east). Mark the east, west, north and south first when you do the problem. )

I can read the simple road map and describe the walking route.

Be sure to write clearly where to go, how many meters you have walked, and where to go again. The same place can be described in different ways. The school is in the west of the theater, in the east of the library, in the south of the bookstore and in the north of the post office. ) There are different walking routes in the same place. Usually find a shorter route.

Children in the third grade are usually 8-9 years old. From the perspective of children's physical and mental development, this age group is a very critical period in children's development (7- 12 years old). Why do you say that?

Because at this time, the child's brain development is just in the period of perfect internal structure and function, and the thinking level gradually transits from concrete image thinking in childhood to abstract logical thinking, and the key turning point is in these two years, which are the initial formation period of children's abstract logical thinking.

At the same time, the stability of children's attention has also improved, and their memory ability, understanding ability and expression ability have developed rapidly. So this age group is a key leap from quantitative change to qualitative change.

Learning characteristics of junior high school students

In addition, the learning characteristics at this stage of grade three are also different. As we all know, children mainly learn letters, literacy and writing in grade one or two, and begin to learn reading and writing after grade three. Therefore, the mode of reading for learning has become the dominant mode of teachers' teaching.

In this year, if some children fail to successfully complete the leap of fast and fluent reading, it means that they have fallen behind now, and this gap will continue to widen in future study.

Therefore, Donald, a sociology professor at City University of new york? Hernandez called the third grade "fulcrum"-a critical transitional period. In a study he conducted, he also found that students who lacked proficient reading skills in the third grade were four times more likely to drop out of high school than other students.

Why is this? Because some students are likely to be depressed in the fourth grade after studying hard in the third grade, and more and more knowledge learned in the school needs to be read in the whole article and understood in the context, other disciplines such as sociology, science, history and even mathematics have begun to rely more on reading analysis.

Therefore, the third grade is a year in which students change from study to reading. Those students with strong reading ability and many reading skills can learn more new words and accumulate knowledge by understanding the context, and their learning progress will be very fast.

And some students with weak reading ability will fall behind in some subjects in addition to studying hard. These students are likely to stop reading in order to avoid failure.
