The experimental conclusion of how high 100 million coins are.
1 100 million one-dollar coins are piled up to be 200,000 meters high. ?

First, the calculation method:

According to the basic arithmetic of mathematics, 1 100 million is 10/0 million times, so the stacking height of 1 100 million coins should be 10 million times of the same coin, that is, 200,000 meters.

Second, the mathematical experiment:

It is a good way to stimulate students' curiosity about the unknown world, stimulate students' desire to explore the nature and laws of things and develop students' higher-order thinking. It is a powerful measure to cultivate students' practical ability and innovative ability, and it is also a powerful starting point to promote the reform of subject education methods.

Based on the idea of developing students' thinking, teachers guide students to deeply understand mathematical knowledge through mathematical experiments, so that students can combine their hands and brains, go through a complete exploration process, find mathematical conclusions or seek proof methods, thus effectively solving problems and developing their thinking ability.
