100 People

In the 1990s researchers calculated that if there were just 100 people in the world, there would be 20 children, 25 people would not have food and shelter, 17 people would speak Chinese, and 8 would speak English.

In this task, you are asked to estimate the real numbers, given that there are approximately seven billion people in the world.

Mathematical Content Standards

This task asks students to select and apply mathematical content from across the grades, including the content standards:

Note: These references are provisional: we are still developing our critera for consistently linking individual tasks to the CCSS.

MAP Assessment Task Types

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.
