| Abstract | The Maine Learning Results (MLR) expects the state's students in prekindergarten through grade 2 to describe two-dimensional shapes as well as use positional language. Requiring translations of two-dimensional shapes supports this expectation. Students in grades 3-4 are expected to "use transformations," while students in grade 5-8 are expected to use coordinate systems and geometric tools to measure and construct two-dimensional figures. Finally, the MLR expects secondary school students to use coordinates to represent figures and their respective transformations. Taken collectively, experiences such as these set students up for success if they find themselves using the language of linear algebra and matrices to understand linear transformations. The MLR expectations, through activities such as "Tessellating T-shirts," are revealing and underscore the importance of mathematics for preservice teachers. The lesson also situates geometry into the wider context of history and art and gives students a foundation that will help them understand fractals. In this article, the authors describe introducing transformational geometry to preservice teachers as well as to elementary-age students through tessellations. They take multiple approaches to tessellations depending on their audience. Here they discuss their approaches to two different audiences. (Contains 8 figures.) (ERIC). |
