There are 10 small questions in the fill-in-the-blank question, and the knowledge points involved include the contents of the book. Several problems of this 10 need special attention. Question 1 pay attention to the composition and writing of numbers, which is one percent, that is, 1 100. The second question is also about the composition of numbers. Pay attention to the difference between numbers. The two adjacent numbers are negative 1 and positive 1 respectively.
The fourth question, three eights add up to 24. The fifth question, how much is the difference? More than 2 to 78 is 78+2. The largest two digits are 99, and the smallest three digits are 100, so you need to add 1.
Question 7, pay attention to the difference between unit and ten. Ten digits is six, which means six tens. Question 8 needs to be mastered. Two identical triangles can be combined into a parallelogram. Question 9 is to find the law and subtract 8 in turn, so the following is to subtract 8 in turn. 10 is a bit difficult. After giving my brother three potions, it is equal, so my sister has two more 3s than my brother, so it is 6.
This problem is mainly about unit conversion and simple calculation, so we should pay attention to the calculation of Jiao Yuanfen and unit conversion. There are large and small units, so we should first pay attention to unifying them. If there is a formula, we need to calculate the results first, and then compare the sizes.
There are six small questions in the multiple-choice question, and several of them need attention. The second question, paying attention to much less means much less, so it is 16 trees. Question 4 is a bit difficult, and many students don't quite understand it. You can draw a picture by drawing. Question 5 compares children's spatial ability and observation ability, so it's me.
Find a routine method:
1, serial number: to find a regular topic, a series of quantities arranged in a certain order are usually given, and we are required to find a general rule according to these known quantities. Find out the rule, usually the serial number of the package. Therefore, it is easier to find the mystery by comparing variables with serial numbers.
2. Fibonacci sequence method: each number is the sum of the first two numbers.
3. arithmetic progression method: the difference between every two numbers is equal.
4. Tabbing method: You can look at it every once in a while to see what the relationship between the separated numbers is, for example, 14, 1, 12, 3, 10, 5, odd items become arithmetic progression, even items also become arithmetic progression, and then you have to fill in 8.
