Presenting the Bar Model method

This video explains what the Bar Model method is, and demonstrates it with some concrete examples.

The Bar Model method refers to a particular mathematical problem-solving approach using rectangular bars as pictorial representation of the quantities, and the relationships between quantities, in problem situations.

Different model methods can be used to solve different types of mathematics problems. There are five models:

1. Part-part-whole model

2. Comparison model

3. Multiplication model

4. Partition/Rate model

5. Combination model

Examples from two of these are shown and explained in this video.
