Photo by Mykl Roventine via FlickrWe were discussing circles.
I knew there was some magical truth,
but what?
Measure a circle.
Measure its...
diameter?
Circumference?
And then what?
He remembered.
He retains so many facts; I retain thoughts and feelings, emotions and memories.
"Measure the circumference of that trampoline," he said.
Kids grabbed the coveted tape measure, all wanting a chance.
We all held on to a point on the circle, he and the children and I, steadying the tape.
"Now measure the diameter," he said.
Again, they scrambled, eager to get their hands on that tool.
It was cumbersome, but they worked it into submission.
We talked about fractions.
We talked about division.
We talked about multiplication.
"How many pieces of candy does each person get?"
Circles on paper,
divide them, divide them, divide them
until they are only hash marks on a page.
1
1/2
1/4
1/8
1/16
1/32
On and on and on.
More circles, this time using the jumprope, measuring its half and multiplying by two.
We divided the circumference by the diameter.
Again and again,
the answer was 3.14
A light went on!
And another!
He drew a symbol on the board.
"This," he said, "is PI."
Chalk figures on the green board
Represented members of the family.
Four girls.
Four boys (counting Papa)
And that's how we discussed ratios.
1 girl for every 1 boy.
A ratio.
1:1
Four boys and four girls became eight people,
And there were more sketched figures,
this time the four-legged variety.
There were four dogs and eight people.
Each dog wanted to walk how many people?
Be fair!
That ratio was 2:1.
And then there were more circles;
On paper with a pencil,
On the hardwood floor with chalk,
with a brother in the center holding the rope
with a sister marking the circumference.
Out came the protractors.
Out came the compasses.
A happy nine-year-old boy,
his six-year-old sister
close behind
"I just learned PI,"
proudly announced
the happy nine-year-old boy.
"I know what the sign for PI is!"
proudly added
the six-year-old sister.
It's just after twelve a.m.
In this family,
We enjoy a little bit
of PI at midnight.
