Abstract
In this curriculum unit, students will begin by exploring lines, points, and planes and developing working definitions. Angles are a logical next step. With these concepts and vocabulary in place, students can progress to the exploration of two dimensional planar geometric shapes, using examples to deduce attributes and non-examples to clarify and solidify their thinking. The basic idea that dividing a shape produces a fractional part will be introduced after this. The last key element to experiment with is movement on a plane. This will prepare the students to look at Native American patterns and pottery designs and analyze the ways in which geometry was used to create those designs. As the students move forward, new vocabulary in both English and Navajo will be added to their knowledge base.
