When a math educator is hell-bent to depicting an idiot-proof version of Singapore’s bar model method as a non-algebraic solution to a word problem to impress upon teachers and writers that most of their clumsily or amateurishly constructed bar models often confuse rather than enlighten their green audiences.
Singapore math writers ought to mindfully and elegantly incorporate bar modeling in their solutions to brain-unfriendly math questions if they are dead serious in marketing the intuitive problem-solving visualization strategy to skeptical math teachers overseas—they need to creatively evangelize the “bar modeling made ridiculously simple” gospel far and wide to win over new converts.
