How it works

Students are presented with an arithmetic expression and an area model tool for constructing an area model instance that reflects the algorithm used to evaluate the expression.

Students can divide the model horizontally and vertically to create a grid of the proper dimensions. They add values into each of the cells and column and row labels. They can also add annotations to each of the elements to explain their thinking.

Area model questions are automatically scored to provide either immediately or delayed feedback to the student and instructor.
