visual model that can be assessed for a path to solution which can be more intuitive than other traditional methods of solving equations using rules. This lesson focusses on representing word problems as equations and using the Part-Part-Total / Bar Model for problems that have two steps.
These problems are slightly more challenging, but they also illustrate how helpful the block diagrams can be, How to solve word problems with four types of bar models - Comparing, Taking Out, Combining, Missing Part, with video lessons, examples and step-by-step solutions.
