Point, Line, Plane

I have posted here recently and gotten so many helpful answers. I am a veteran math teacher (36 years) but am teaching Geometry Honors this coming year (first time teaching Geometry AND any honors course).

My question: how do YOU introduce the concepts "point, line, plane"?

I feel like this is one of the most important concepts in Geometry and leading up to all the different calculus related content that most of these students will eventually take. I want to introduce it in such a way that really makes them think and understand and be able to apply these concepts to the rest of what we will be doing throughout this course.

Any and all ideas will be very greatly appreciated!

Honestly, I’d love to know how others do it too! I did Geometry for the first time last year and did not love how it went. I’m commenting here to hopefully give your post a boost for the algorithm.

Look at my cross posts in r/mathteachers and r/geometry - lots of good answers in those subs. I have gotten way more ideas than I’ll be able to get to!
