•  Model Drawing
    Since the early 1980s, a distinguishing characteristic of the math
    taught in Singapore—a top performing nation as seen on the Trends
    in International Math and Science Study (TIMSS) reports of 1995,
    1999, 2003, and 2007—is the use of “model drawing”. Model drawing,
    often called “bar modeling” in the U.S., is a systematic method of
    representing word problems and number relationships that is explicitly
    taught beginning in second grade and extending all the way to
    secondary algebra. Students are taught to use rectangular “bars” to
    represent the relationship between known and unknown numerical
    quantities and to solve problems related to these quantities.
