Students’ Conceptual Challenges
Both Mauricio and Emily seemed to understand quickly what the task was asking them to do. However, be on the lookout for students who might not realize that they need to subtract from the length of the original garden. You can ask students to revoice the task with a partner or ask a student to clarify the task with the whole class before moving on.
