Description

In this assessment, students are presented with a scenario that involves using a variable to represent the length of different wall sections in a room that needs to be painted. As students work through the scenario following logical steps in their calculations, they describe their steps, suggest corrections to given estimates, identify polynomial expressions, calculate lengths and areas, and explain/justify the degree of accuracy used and whether the findings make sense. By the end of the task, students find and justify the possible value of the initial variable.
