Knowledge points of "understanding Jiao Yuanfen" in the first grade of primary school mathematics
1 yuan = 10 angle = 100 point.
1 angle = 10 point
1 yuan =(2) 5 angle =( 10) 1 angle =(5) 2 angle.
5 yuan =(5) sheets 1 yuan.
10 yuan =( 10) 1 yuan =(5) 2 yuan =(2) 5 yuan.
20 yuan =(2) 10 yuan =(20) 1 yuan.
50 yuan =(5) 10 yuan =(50) 1 yuan = () 20 yuan +() 10 yuan.
100 yuan =( 10 pieces) 10 yuan =( 100 pieces) 1 yuan.
Amount paid-amount spent = amount recovered (remaining amount)
Money spent+money recovered = money paid.
Amount paid-amount recovered = amount spent (commodity price)
Sorting out the knowledge points of mathematics in the first grade of primary school
1. Know the unit yuan, angle, minutes and their decimal relations of RMB, know RMB of various denominations, know the unit price of articles, and make a simple calculation.
2. Combine your own life experience and the knowledge you have mastered within 100 to learn and understand RMB. On the one hand, you know the basic knowledge of RMB and how to use it, thus improving your social practice ability; On the other hand, deepen the understanding of the concept of numbers within 100.
3. Experience the close connection between the concept of number and real life.
4. Know RMB of various denominations and make a simple calculation.
5. Make students know the unit yuan, angle and minute of RMB, and know 1 yuan = 10 angle, 1 angle = 10 point.
6. Through shopping activities, students can have a preliminary understanding of the functions and functions of RMB in social life and commodity exchange, and know how to cherish RMB.
Knowledge points of mathematics observation and measurement in senior one.
Observation and measurement
1, observing the object-(observing the shape of a single object from two directions)
2. How long is this table? (Understanding in centimeters)
3, go to the amusement park-(Zhifan)
4, estimation, measurement-(simple estimation and measurement)
Observing an object (observing the shape of a single object from two directions)
1. By observing the real thing, I realized that the shape of the object seen from two directions (front (back) or side) may be different.
2, will recognize the shape of a single object observed from two directions.
How long is this table?
1, through the process of measuring the length of the same object with different measuring tools, I realized the necessity of unifying the length unit.
2. Know centimeters, find out which objects around you are 1cm in length, and realize the practical significance of 1cm.
3. Be able to estimate the length of small objects and measure the length of objects correctly with a scale.
4, will observe the length of the object through the ruler. (Starting point is not 0 scale)
5, according to the length of the object, choose the appropriate scale measurement.
Go to the amusement park (zhifan)
1. Initially establish the concept of the length of the meter. According to the actual length of 1 cm and 1 cm, we know that 1 m = 100 cm, and initially learn to estimate the length of an object.
2, master the relationship between meters and centimeters, and can properly choose the length of the unit representation.
3, know the meter ruler, will use the meter ruler to measure the length of the object.
Estimation and measurement (simple estimation and measurement)
1, you can choose an appropriate unit to express the length.
Can estimate the length of objects around you, and will use measuring tools to measure.
2, will recognize the shape of a single object observed from two directions.
