Finding The Areas Of Rectangles, TrIangles, parallelograms, and trapezoids through formulas are part of most state mathematics standards and are included in middle school mathematics textbooks. Students are expected to know these formulas and apply them to find the areas of figures shown in textbooks. But as the TIMSS 1995 video study pointed out, students in the united States are seldom given the opportunity to discover the formulas for themselves (Stigler and Hiebert 2004). This article provides activities that prompt students to investigate and discover the formulas, with a teacher's guidance. Finally, students work with a nonstandard unit of area measure, an equilateral triangle, to investigate area formulas using this unit.

Have You Ever Wondered how to use children's literature in a middle school mathematics classroom? In today's standards-driven environment, aligning activities to various standards is important. Children's books can be the perfect introduction to a unit or lesson. Paying careful attention to the elements in the story and using a little imagination, creativity, and a working knowledge of the mathematics Standards are all the items needed to begin.

School Classroom

An examination of middle school mathematics textbooks published prior to the 1990s reveals that the statistics component consists mainly of computing averages and drawing simple bar, line, and circle graphs. Although finding centers or averages of data sets or conducting surveys and graphing the results are certainly appropriate activities. they usually involve only collecting and organizing data and do not focus on understanding or interpreting the data
