When mathepreneurs see a multi-million dollar business opportunity to provide both resources and training for tens of thousands of seniors who are eager to learn about the “bar model method”—the heart of the Singapore elementary math curriculum—in order to connect and engage with their grandchildren’s and godchildren’s math education.
Publishers and vocational training centers have been pretty slow at taking advantage of the untapped source of revenue offered by the silver bar modeling industry, especially when more seniors are enjoying a longer lifespan in fast-greying Singapore.

Get the Silver Bar Modeling mug.A mix of intuitive bar modeling and abstract algebra to solve word problems, which serves as a bridge from pre-algebraic thinking (hidden in the Singapore bar model method) to formal algebraic thinking (involved in solving an equation).
Many middle school students in Singapore are so fluent in the bar model method that teachers and parents find it hard to wean them from it in order to embrace the algebraic method. As a result, some math educators suggest using the blended or hybrid modeling to make the transition less painful.

Get the Hybrid Modeling mug.When incorporating Singapore’s bar model method—the problem-solving visualization strategy to tackle word problems—at the elementary school level and its aim to develop students’ pre-algebraic thinking skills (before they are introduced to formal algebra) are not often partially achievable or necessarily correlated in practice.
Wallet-friendly Singapore math textbooks, workbooks, and teachers’ resources on their own doesn’t guarantee problem-solving mastery—bar-modeling orthogonality seems to be a constant in many traditional American classrooms, often because of teachers’ or parents’ faux perception that a foreign math curriculum or publication is harder (or even inferior) than their local inch-deep-mile-wide one.

Get the Bar-Modeling Orthogonality mug.The mathematical equivalent of a child riding a tricycle before switching to a bicycle, or using a float while learning to swim—using bar diagrams instead of forming algebraic equations to solve word problems.
Bar modeling, which is the heart and soul of the Singapore math curriculum, acts a bridge between elementary (or primary) math and middle school (or secondary) math—where concrete rectangles or bars are used instead of abstract variables for unknown quantities.
