Ethnomath: Geometric Translations

Ethnomathematics: Geometry - Translations

In this lesson plan, students will learn about geometric translations in Maasai blankets and other African textiles. Students will have the opportunity to practice the concept of geometric translations while exploring these beautifully bold and colorful patterns. This is one of three geometry lessons that focus on ethnomathematics. See also Ethnomath: Geometric Reflections and Ethnomath: Geometric Rotations.

Before starting this lesson, students should have a background in geometric translations.

In this lesson, students will:

1. Learn about the history and use of Maasai blankets (Kenya, Tanzania, East Africa), Kente cloths, and other African textiles
