Bar Model Method

The bar model method (also known as the Singapore bar model, and as a tape diagram or strip diagram in the United States) is a visual strategy for solving arithmetic word problems. Quantities are drawn as rectangular bars to make the relationship between the known and unknown values visible.

Algebrakit offers two variants of the model method:

  • Standard arithmetic models for basic arithmetic word problems for addition, subtraction, multiplication and division
  • Freeform models, allowing setting up any model.
