Summary

Can we classify quadrilaterals like we classify living things?

  1. Students note that living things, as well as quadrilaterals, can be grouped in a variety of different sized categories. They consider how one quadrilateral is similar to and different from two others.
  2. Students learn several criteria for grouping quadrilaterals (right angles, parallel sides, and congruent sides), then revisit their worksheet to increase their level of precision.
  3. Students develop a hierarchy using the criteria from the previous video.
