If there is no dust in the first volume of the fifth grade of primary school, what explanation methods are used

Explanation method: list numbers, analogy, and examples

If there is no dust, what questions will arise

Reflection on the teaching of "if there is no dust"
"If there is no dust" is not only a skimming text, but also an expository text with accurate, vivid language, strong knowledge and interest. There are six natural paragraphs in the full text, which are clear-cut in structure and clearly explain the inseparable relationship between dust and human beings. It reveals a profound philosophy that everything has two sides. Only by correctly understanding them, can we pursue advantages and avoid disadvantages and benefit human beings
In the process of teaching, I mainly focus on students' self-study, focusing on stimulating their interest in learning and giving appropriate guidance
1、 In the activity, stimulate students' ability to search and organize materials. Student representatives interview students: from your preview homework, do you know what dust is like? How does dust shine? What's your attitude towards dust? What's people's attitude towards dust from ancient times to modern times? Which sentence is used in the book to express it? So that students can discover and acquire knowledge by themselves, Let the Chinese classroom full of vitality

Their difference is 1,7,19,37,61, and the difference of the last five numbers is 6,2 * 6,3 * 6

If the sequence {an} satisfies A1 = 2, an + 1 = − 1An + 1, then A2010 is equal to ()
A. 2B. −13C. −32D. 1

∵ A1 = 2, ∵ A2 = − 12 + 1 = - 13, A3 = − 32, A4 = 2, and so on, the sequence is a sequence with period 3, ∵ A2010 = A3 = − 32, so select C

Indefinite integral Find the original function of α * e * (* is x )
By direct method Detailed steps X power of a times x power of e

Formula: ∫ a ^ x DX = a ^ X / LNA + C
∫ (a^x)(e^x) dx
= ∫ (ae)^x dx
= (ae)^x/ln(ae) + C
= (a^x)(e^x)/(1 + lna) + C

When n = 6, the first row is 1 23 4 5 6, the second row is 3 57 9 11, the third row is 8 12 16 20, the fourth row is 20 28 36, and the fifth row is 48 64
The sixth line is 112. At this time, the number of the last line is 112. When n = 2009, what is the number of the last line

The sum of the first and last two numbers in the next row is twice the sum of the first and last two numbers in the next row. From n = 6, we can see that the nth row is equal to the sum of the first and last two numbers in the first row multiplied by the power of 2 (n-2). Therefore, when n = 2009, the 2007th power of (1 + 2009) * 2 in the 2009 row is the power of 2010 * 2

A is a natural number greater than 0. When a (), 8 / A is a true fraction, when a (), 8 / A is a false fraction, and when a (), 8 / a can be converted into an integer

A is a natural number greater than 0. When a is less than 8, a out of 8 is a true fraction. When a is more than 8, a out of 8 is a false fraction. When a is an integral multiple of 8, a out of 8 can be converted into an integer

The numbers are arranged as follows: 1, 3, 8, 18, 36,..., what are the sixth and seventh numbers

（1+3）+4＝8
（3+8）+7＝18
（8+18）+10＝36
（18+36）+13＝67
（36+67）+16＝119
