30÷2= 15 (times)
15+ 1= 16 (times)
A: You need to jump 16 times.
This question not only examines students' mathematical thinking, but also examines students' logical ability.
Because every jump of two meters is 30÷2= 15 (times). This 15 only jumps to the wellhead, not to the wellhead, so it needs 15+ 1= 16 (times).
But when this problem is regarded as a logical problem, the frog will never jump out, because it will fall every time it jumps.
Logical thinking ability is the core of children's intellectual activity ability and intellectual structure, so logical thinking ability is one of the most important intellectual factors for children to become talents.
Logical thinking ability plays a very important role in any stage of a person's life. In the early stage of children's thinking ability development, if parents pay attention to cultivating children's logical thinking ability, it will play a very important and fundamental role in children's development.

Simple application problem solving method:
1, comprehensive method
The idea of solving problems by comprehensive method is to shift from known conditions to analytical methods of problems. The analysis method is: choose two known quantities and put forward the problems that can be solved; Then choose two known quantities and put forward the problems that can be solved; This is deduced step by step until the problem of the topic is solved.
2. Analytical method
The idea of analytical method is to start with the problem of application problems and find out the conditions needed to solve this problem according to the quantitative relationship. Some of these situations are known and some are unknown. Then, take the unknown condition as an intermediate problem, find out the conditions needed to solve this intermediate problem, and reason step by step until all the necessary conditions can be found from the topic.
