you could do a basic mandela...
my lesson is on IAD but I've put it here for convenience
Here's the basics!
- Students had one piece of white computer paper.
- Students were instructed to draw one line, 8 inches long (close to the
edge of the page) (8 inches will produce a 16 inch finished circle).
- Using a protractor, students then measured 30 degrees (exactly!!! very
important that it is exact!) - Students were then to draw a second line 8
inches long to complete the 30 degree wedge. You could provide the students
with a photocopy of a wedge - make sure it is LIGHT however, becuase you do
not want heavy black lines on the edge of each wedge...
- Once the wedge was drawn, students planned out thier design in pencil.
- Students had a few criteria: there needed to be at least 3 continuous
elements (things that would line up and continue all the way around), 2
stand-alone items (things that would line up), a variety of line types
(thin, thick, etc), and a balance between positive and negative (black and
- Students were instructed on how to line things up ie: measure 3 inches up
on one side of the wedge, then 3 inches up on the other side of the wedge.
A line drawn between those two points will line up and go all the way around
the circle when the wedges are put together.
- Students then completed thier wedge using black fine pen and a black
sharpie marker. It is important to remember not to outline the wedge. This
will cause a repeated black line seperating each section of the pie. If you
want to have contiuous white sections, then the wedge can not be outlined.
I had my student leave the wedge lines on the paper lightly in pencil, as
the photocopier did pick it up slightly, and it allowed the students to know
where to cut the wedge out....
- Students then handed this is....
I took all the wedges to the photocopier and reproduced them 13 times each!
(12 needed for the pie, plus one extra for mistakes).
- taking a large sheet of cartridge (18 x 24") students drew a very light
pencil line approximately in the centre. Using the protractor, students
marked every 30 degrees with a small light dash. This was learned after the
first class made a bunch of mistakes......It allows the students to know
very quickly if their wedge is off from 30 degrees. If it is too small,
they need to spread out the spaces throughout the circle (and then fill in
the spaces with black marker afterwards). If it is too big, they need to
space out the overlapping over the entire circle and no one will know the
- Students then carefully cut out all the wedges, and glued them onto a 18 x
24 inch sheet of white cartridge.
- Students then cut out the finished rose window/mandella
It really only takes a few days....one for the design, one or two for the
cutting and glueing - and the "ohh ahh" effect is high when they are done!
You could easily make this simplier, by increasing the wedge size...
ie: 30 degrees means 12 wedges but 60 degrees means only 6 wedges (which
would also be nice!)
