  • Properties of Parallelograms and Rectangles
    Dynamic geometry software provides an environment in which students can explore geometric relationships and make and test conjectures. In this example, properties of rectangles and parallelograms are examined. The emphasis is on identifying what distinguishes a rectangle from a more general parallelogram.
  • Shapes at Work
    Students record shapes that they find around them, identifying those that can be used to solve practical problems and build larger structures. Students will explore the uses of various shapes and record their findings in a science journal.
  • What's In a Shape?
    The purpose of this lesson is to explore characteristics of shapes by making and using tangram sets; to discover how the tangram pieces are related to one another; and to determine how many different combinations of the triangles, squares, and parallelograms in tangram sets can make a given shape.
