Summary
Can we classify quadrilaterals like we classify living things?
- 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.
- Students learn several criteria for grouping quadrilaterals (right angles, parallel sides, and congruent sides), then revisit their worksheet to increase their level of precision.
- Students develop a hierarchy using the criteria from the previous video.
