Analysis: This question must first distinguish the direction (the left hand direction refers to the left, and the right hand direction refers to the right), and then learn to know the cardinal number and ordinal number, that is, 1). How many cardinality (one can be a multiple); 2) Ordinal number indicates position and order, with the first number before the first word.
2. Small animals get together.
Left 1 2 3 4 5 6 7
7 1 right
(1) Seven small animals came from a * * *;
(2) Xiao Lv ranks fourth in the left;
(3) The small animals in the sixth row on the right are small monkeys.
Analysis: This problem is a simple single-line queuing problem. Clear the direction first, then mark it to solve the problem (mark the counting problem so as not to repeat or miss it).
3. Compare the sizes of the following numbers and put "
8(& lt； ) 19 12(& gt； ) 10 5 1(& gt； ) 15
5+6(& gt； )3+73+ 19(& gt； )2 1 8+9(=)3+ 14
Analysis: This question should be mastered skillfully. The use of "<" "=", (greater than a large number of grinning smiles, less than a small number of sharp spikes); In addition, the comparison between numbers, 1) first looks at the number of digits, the more digits, the greater the number; 2) If the digits are the same, compare the highest digits. The largest number of digits is the largest. If the highest digit is the same, it depends on the second highest digit, and so on.
4. In an exam, the dinosaur scored 95 points, the fish scored 78 points, the pig scored 6 1 point, the deer scored 83 points and the duckling scored 9 1 point. Son, can you sort the test scores from high to low? Who is the tallest and cleverest in the exam? Please circle it.
(95)>(9 1)>(83)>(78)>(6 1)
(dinosaur) > (duckling) > (deer) > (small fish) > (pig)
Dinosaurs got the highest test and were the cleverest.
Analysis: This question still needs to be familiar with the comparison between numbers. If the numbers are the same, look at the highest number first. If the number with the highest digit is large, it will be large. If the highest digits are the same, we must look at the second highest digit.
