The task These work samples were drawn from different classrooms. Both teachers gave the same instructions to their class. The teachers asked their classes to draw four creatures. They instructed the students to cut the figures into four heads and four bodies and to staple each set into a small “flip book.” The teachers asked: How many characters could you possibly come up with by combining the different parts in various ways? Show and explain in detail all the combinations you could make. Sample 1

 Circumstances of performance These samples of student work were produced under the following conditions: - alone in a group - in class as homework - with teacher feedback with peer feedback timed - opportunity for revision
 These work samples illustrate standard-setting performances for the following parts of the standards: f Statistics and Probability Concepts: Find all possible combinations. b Problem Solving and Reasoning: Implementation. c Problem Solving and Reasoning: Conclusion. b Mathematical Communication: Show mathematical ideas in a variety of ways. c Mathematical Communication: Explain solutions to problems clearly and logically. d Mathematical Communication: Consider purpose and audience when communicating about mathematics.
