James, an
airplane buff
James is four years old. But he is not an ordinary four years old. He
loves airplanes and knows more about airplanes than most adults would
know. Certainly, James knows more about planes than I do.
One day in October last year, James had a routine four-year-old check up.
Before I started my routine physical examination, I tested his math
ability. I took my four "fraction blocks." I threw it in front of him on
top of the examining table. I requested James to count the blocks. Without
hesitation, James said, "four." I then arrange the four blocks to form a
square. Then I asked him, "What shape is this?" He said, "Square." We did
a high five and I said, "Good job."
I lifted one of the blocks and I told James, "This is one fourth." I
placed it back to make a complete square again, and specifically said,
"Now we have a whole square again." Then I took another block and said,
"This is another one fourth." And I brought it back to restore the square
again.
I lifted the third block, and I asked James, "What do you call this?"
Without a delay, James responded, "One fourth." I showed my excitement by
saying, "Great." And we did a high five again. Then I took two of blocks
and held it with its sides touching each other forming a rectangle and I
asked him, "What do you call this?" James said deliberately, "Two
fourths." I then took another block and held the three of them in an "L"
form, and I asked James, "What do you call this now?" "Three fourths,"
without faltering. Then I took the last block and brought it up with the
three to form a square and I queried him, "Now what is do you call this?"
James without delay in responding said, "Four fourths."
Then I took two rectangular blocks forming a square the size of which is
the same as the four blocks that I used to demonstrate fractions of
fourths to James. I lifted one of the rectangle and I told James, "This is
one half." And I placed it back touching the side of the other rectangle
forming a square. Then I lifted the other rectangle and I asked James,
"What do you call this?" He said, "One half."
I took two of the square blocks that I used to demonstrate "fourths" and
placed it on top of one the rectangle, and I said, "Two fourths is the
same as one half" holding both the rectangle and two of the "fourth"
blocks together showing that both of them are of the same size.
I returned the rectangle to its original position with the other rectangle
to form a square again. While still holding the two square blocks with
its side touching each other, I asked James, "What to do you call this?"
He said, "One half."
Then I drew a circle about 6 inches diameter with a ball pen on the white
examining table. I drew a line dividing the circle into two halves. I
shaded with a ball pen one half of the circle. I asked James, "What to you
call this" He said, "semi-circle." I was surprised with his answer, but he
was right, so I said, "you're right, a semi-circle." But what else to you
call it," James said, "One half."
I drew another circle and divided it into fourths. James was able to
identify one fourth, two fourths, three fourths, and four fourths of the
circle.
I changed the topic and I asked him, "What do you call the person who
flies an airplane?" He said, "Wright brothers." His mother interrupted and
asked, "In what state was the first airplane made?" James said, "North
Carolina." In
what town his mom asked, and he said, "Kitty
Hawk." "What
is the name of the bomber that dropped the atomic bombs at
Hiroshima?"
James had a quick answered, "Enola gay." James collects small airplane
models. He knows a lot about airplanes more than most adults.
James is one of my smartest patients who is a "graduate" of our smart baby
program at our office.
