Steve and Mark are both filling their own bucket with water. -Steven begins with 8 cups of water in his bucket, and fills the bucket at a rate of 2 cups per second.
- The number of cups of water, W, in Mark's bucket after t seconds is represented by the equation w= 8t + 1

A. Mark begins with more cups of water in his bucket
B. Mark begins with the same amount of water as Steven
C. Mark fills his bucket at a faster rate than Steven
D. Mark fills his bucket at the same rate as Steven

Use of multiple representations supports and requires tasks that involve decision-making and other problem-solving skills.[The choice of which representation to use, the task of making representations given other representations, and the understanding of how changes in one representation affect others are examples of such mathematically sophisticated activities.[citation needed] Estimation, another complex task, can strongly benefit from multiple representations 

Curricula that support starting from conceptual understanding, then developing procedural fluency, for example, AIMS Foundation Activities, frequently use multiple representations.

Supporting student use of multiple representations may lead to more open-ended problems, or at least accepting multiple methods of solutions and forms of answers. Project-based learning units, such as WebQuests, typically call for several representations.
