r from the
left-back corner to the right-front corner.--Margaret, what are you to
do?"

_Margaret_: "I am to lay my ruler on my paper from the left-back corner
to the right-front corner."

_Teacher_: "Draw a line connecting the left-back corner of your paper
with the right-front corner.--James, what did you draw?"

_James_: "I drew a line connecting the left-back corner of my paper
with the right-front corner."

_Teacher_: "Alice, what have you drawn?"

_Alice_: "I have drawn a line connecting the left-back corner of my
paper with the right-front corner."

Now have the children draw a line connecting the reverse diagonal
corners and proceed as follows:

_Teacher_: "Find the point where the lines cross. This is the center or
middle point of your paper.--Albert, what are you to find?"

_Albert_: "I am to find the point where the lines cross, which is the
center of my paper."

_Teacher_: "Measure one inch from this point on each of the four lines
and place a dot.--Sara, what did you measure?"

_Sara_: "I measured one inch from the center of my paper on each of the
four lines and placed a dot."

_Teacher_: "Lay your pencil and your ruler down. Place your paper on
your desk parallel with its front edge and lay your left hand on the
right-front corner. Turn the paper until this corner is directly in
front of you. Take your scissors and cut along the ruled line from the
corner to the point one inch from the center.

"Lay down your scissors. Turn your paper from right to left until the
next corner faces you. Cut. Move the paper from right to left again
until the third corner faces you. Cut. Bring the fourth corner to face
you. Cut. There are now eight points. Turn each alternate point to the
center, run the pin through all of them and fasten the wheel to the
stick."

_Final questions._

_Teacher_: "What did you make?"

_Pupil_: "I made a pin-wheel."

_Teacher_: "What have you made?"

_Pupil_: "I have made a pin-wheel."

_Teacher_: "What has Ellen made?"

_Pupil_: "Ellen has made a pin-wheel."

When older pupils have completed a model it is excellent practice to
have them write a full description of how it is made and the materials
used.
