Learn about the characteristics of different kinds of quadrilaterals, including parallelograms and rhombuses, in this video from KCPT. In the accompanying classroom activity, students classify quadrilaterals._
Give students 2 minutes to list as many different types of quadrilaterals that they can. When time is up, reassemble as a class and have students share their lists. Identify and eliminate shapes that are not quadrilaterals and discuss reasons why.
2. Watch the Video (5 minutes, whole group)
Show students the video.
3. Investigation (10 minutes, small groups)
At the conclusion of the video, distribute the activity sheet and have students complete it in groups of two to three.
4. Conclusion (5 minutes, whole group)
Discuss whether a shape can be a quadrilateral, parallelogram, rhombus, square, rectangle, and trapezoid all at the same time.
Activity Extension: Ask students to draw a Venn diagram showing how quadrilaterals, parallelograms, rhombuses, rectangles, trapezoids, squares, and other quadrilaterals are related.
