Objective: to decorate a bulletin board with "quilt" patterns illustrating various types of symmetry.
- Divide the class into three groups. One group will illustrate
translations (easiest), one will illustrate rotations, and one will
illustrate reflections (potentially hardest).
- Choose a pattern for your group's quilt square either by
inventing your own or or choosing from a book of quilting patterns.
While choosing a square, keep in mind that you will have to produce
several copies of the square and may have to create reflected versions
of your square.
- Based on the squares chosen and group preferences, decide which
of reflection, rotation or translation your group will illustrate.
Make sure each group illustrates a different type of symmetry.
- You will create a "quilt" by assembling a dozen copies of your
chosen square into a three by four block (or larger). How large
should each square be in order to best use the materials provided and
the space available? How many copies of your square will you need to
illustrate your type of symmetry?
- Plan how you will illustrate your assigned symmetry. Use red
lines to illustrate some lines of reflection in your quilt or use blue
dots to mark centers of rotation. What labels will you need? Consult
with other groups to be sure that your styles agree. (Will labels be
hand written or computer printed? If printed, what font and font size
will you use? Use a white or light background with dark lettering on
your labels to ensure readability. Do you want a block of text by
each "quilt" or will the symmetries speak for themselves?)
- The entire class should choose a title for the bulletin board;
this title should probably be computer printed with each letter on a
separate rectangle of paper. How big do the letters need to be?
- List the materials you will need to decorate the bulletin
board. (Background paper, staplers, glue, scissors, construction
paper, white paper, markers, borders, printouts, ...?)
- Choose a background color for the bulletin board, create your
quilt squares and labels, and decorate the board!
