Problem Solving Strategy: Using Singapore Bar Models #rolandoasisten || MATHEMATICS IN THE MODERN WORLD | VIDEO NO. 12 In this lesson, we try to demonstrate the use of the Singapore Bar model as a tool for problem-solving. Due to the spatial nature of quantities, and with many math concepts having some interpretations in space-time dimensions, using a bar model is a more efficient way to estimate and visualize number relations compared to moving directly to the use of algebraic symbols. It can f
