E11: Taxi Cabs
In this task, you must use math to find the best way to organize cabs for a large group of people.
This task asks students to select and apply mathematical content from across the grades, including the content standards:
- 7.NS: Apply and extend previous understandings of operations with fractions to add, subtract, multiply, and divide rational numbers.
Note: These references are provisional: we are still developing our critera for consistently linking individual tasks to the CCSS.
MAP Assessment Task Types
- Expert Rich, less structured tasks requiring strategic problem-solving skills as well as content knowledge.
The task types indicate the breadth and depth of CCSS mathematical practices assessed by the task. Novice tasks involve only MP2 and MP6 and do so at a low level. Apprentice tasks add MP3 and MP7 but, because of the guidance within the task, do so at a comparatively modest level. Expert tasks aim to cover the full range of practices.
Note: these task types offer a guide as to how tasks relate to the mathematical practices. We are currently considering whether referencing the specific practices relating to each task would be useful or appropriate.
