Think about the platonic solids activity and how it might work for grades
3-5. What must students know and be comfortable with to get the most out of
this activity? What are potential stumbling blocks?
Students must be comfortable with knowing the properties of polygons. They
must understand the angles within polygons in order to see the pattern
emerge with building 3-D objects. They must also be able to make if-then
arguments to determine what solid figures cannot be built, otherwise they
will continue on an un-ending cycle of testing out cases and building with
more and more faces. Some step checks may need to be put in place instead
of leaving the lesson open-ended for students to explore. In addition, some
guiding questions by the teacher could be used to get the class on-track if
they do not connect to the emerging pattern.
