BarModeler is a tool for primary school students and their teachers and/or parents to "draw" bar models in Math by writing code (equations). While the user describes his/her understanding about a word problem by writing equations, the tool can automatically create a bar model to visualize the equations, which will help the user to understand the word problem both abstractly and visually.
BarModeler provides more than 80 sample bar models, most of which are based on the book "Bar Modeling" written by Yeap Ban Har, PhD.
