I’ve captured a video of the BarModel Player for the following word problem:
Ryan had $200 more than Danish at first. Ryan gave ¾ of his money to Danish. Danish in return gave 2/3 of his money to Ryan. In the end, Ryan had $180 more than Danish. Find the amount of money Danish had in the end.
You can see how the bar model is created step by step, and boxes moving from one bar to another bar in action.
