Introduction
The
Bar
Model Method
is the key feature of the well-
known
Singapore Math
which refers to the teaching
strategies adopted in the textbooks written by a project
team led by Dr Kho Teck Hong of the Curriculum
Development Institute of Singapore in 1980. Since then
the bar model method gained international attention
and adoption.
The method involves a procedure of drawing bar
models to visualise the concepts of ratios and fractions
and to use them in different situations in word prob
-
lems. The original idea of using line segments instead
of bars to solve problems dates back to Euclid in Book
V of his monumental work
Elements
about 2300 years
ago. In statistics, bars are effectively used to construct
bar charts for representing data and information.
