Lesson Reflection
After school, a lesson reflection was carried out with Mr.. Seiyama
Mr. Seiyama: "Interestingly the students who are usually good at math had difficulties at first. I asked them why later on. Those who are good at math said they were trying to come up with the number to go in the "ones" column first when the difference was 3. Those who unexpectedly got the right answers instead looked at the problem as a whole. Because the difference is 3, they simply came up with 100 and 97 right away.
