The Tangram Conundrum
Keyword(s):
The tangram is a versatile manipulative used to teach and learn such concepts as shapes, spatial relationships, fractions, percents, area, and perimeter. When I introduce it to undergraduate preservice teachers, they are drawn to the tangram because of the creative ways in which the shapes can form images; the book Grandfather Tang's Story (Tompert 1990) illustrates this quality well. The preservice teachers are surprised to find that this simple manipulative can challenge their understanding of some mathematical concepts taught in middle school. This article describes an investigation conducted by preservice teachers enrolled in a mathematics methods course.
