...and this morning I taught the kid how to use a compass. It took a little practice, but she got the hang of it fairly quickly.
She played around with concentric circles, circles that 'go off the page' and even discovered that three circles together can 'make a triangle!'
While she played around, I took a paper plate and a CD. With the CD centered inside the paper plate, I drew one circle tracing the small circle in the center of the disc. Then I played around...until, WOW! Look at that! I made a hexagon! I felt like I had just discovered a dinosaur bone or something. I decided to color it in to highlight the structure.
At that point it was time to go do Sunday things, but it took forever to get out the door. The kid kept finding circles everywhere.
When we got home from Sunday things, we started in on it again. This time, the kid started experimenting with tracing the circles. A straw can make a smaller circle than the compass can.
I made another hexagon out of circles, but colored it in differently, the kid's favorite it turns out.
The kid constructed two different versions of concentric circles (mostly using the compass). "See Mama! They're the reverse of each other. This one has a lot of rings on the inside, but not on the outside. The other circle is the opposite!"
And, then, she wanted to make a hexagon like mine so I showed her how to use the CD center circle. I really like her design sensibility. It's so different from mine.
And then it was time for lunch, but we still have unanswered questions waiting to be resolved. Like, what else can you make with the compass besides circles inside circles? Great question, kid.
I'm fairly certain we've only just begun...
