The Hopewell people were Native Americans whose culture flourished in the central Ohio Valley about 2000 years ago. They constructed earthworks using right triangles.
In this task, you will look at some of the geometrical properties of a Hopewell earthwork.
Mathematical Content Standards
This task asks students to select and apply mathematical content from across the grades, including the content standards:
- 8.G: Understand and apply the Pythagorean Theorem.
- H.G-SRT: Define trigonometric ratios and solve problems involving right triangles
Note: These references are provisional: we are still developing our critera for consistently linking individual tasks to the CCSS.
Assessment Task Type
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.
