Geometry is traditionally taught as a set of rules and formulas to be memorized and applied, but even the most basic geometry concepts can be so much richer. In fact, students can be developing algebraic reasoning and habits of mind from the very beginning of their work in geometry. The early geometric concepts of area and perimeter of rectangles are rich with opportunities to engage students in algebraic reasoning and sophisticated problem-solving. It is not necessary to wait until high levels to introduce algebra!


    This professional development activity/course is designed for:

  • ABE and HSE teachers at all levels of math ability and comfort

In this workshop, you will deepen your understanding of the kinds of reasoning that forms the foundations of algebra and see how that foundation can be developed in geometry lessons, even at the earliest levels. By exploring an activity involving the area and perimeter of a rectangular garden, and the relationship between those quantities, you will broaden your understanding of the levels of reasoning that can be integrated into the study of geometric concepts. This workshop will provide you with a jumping off point for continuing to bring algebraic ideas into math classes at every turn. 

    Learning Objectives

    Upon completion of this professional development activity/course, you will be able to:

  • Facilitate an open question in geometry
  • Recognize algebraic reasoning at informal and formal levels
  • Use informal and formal algebraic language and notation to describe relationships between quantities
