The examples of student work provide a glimpse into the strategies that CMP students use to construct answers. In particular, the examples can help teachers anticipate the strategies that their own students may use to answer the question of how long to make Henri and Emile’s Race.

Students use many strategies when trying to decide how long the race should be for Henri and Emile in the *Moving Straight Ahead*, Problem 2.1: Henri and Emile’s Race. Here we provide examples of student work produced by students in various CMP classrooms. The strategies include students guessing and checking, using a table, making a graph, using visual diagrams, and using the distance between the two boys to reason about the question.

Some of the work is in students’ writing and other work is re-created from actual CMP students. Student answers to the Problem are not included.
