The notes stay with that household and with fractions taught through everyday things, and they do not name a series author.
The notes take up Sintongbangtong Fractions, a math fairytale in a series that teaches ideas through story, meant for children meeting fractions for the first time. They do not name a series author, and none is added here.
The hero, Man-ho, hates math enough to wonder whether some villain invented it to torment children. His family runs a bakery, and when he scores a zero on a math test — a ‘bread score,’ in the Korean pun — a rumor starts that he ate too much bread.
Ju-cheol, who always scores a hundred, is said to eat ‘hundred-point candy,’ and the children all head for his stationery shop. Man-ho’s father, hearing the talk, does not scold or set drills. He tries a ruse.
He appears as Gaedong-i, Man-ho’s son from the future, so that the boy can be taught without the usual scolding. The notes take this as a parent’s invention, not as a lecture.
Gaedong-i, they write, explains fractions from everyday things, starting with the basic idea of division, using colored paper and scissors. The notes prefer this to forcing problems before the idea is in place, which they say only breeds defeat and refusal.
In the long run, they write, what matters is that a child take pleasure in the work and form a habit of doing it himself. They leave the subject there, before later tables. The same Korean report, in a longer form, sits on CampusDown.

An elementary-school child who hates math enough to wonder if some villain invented it to torment children. His family runs a bakery, and a rumor starts when he scores a zero — in Korean, a ‘bread score’ — on a math test.
Instead of scolding, he appears as Gaedong-i, Man-ho’s son from the future, and explains fractions from everyday things, beginning with division, using colored paper and scissors.
Because, they write, setting problems before the idea is in place only breeds a sense of defeat. Better, in the long run, to let a child take pleasure in the work and form a habit of doing it himself. Ju-cheol, who always scores a hundred, is part of the rumor about ‘hundred-point candy.’
