PROJECT: STAINED GLASS WINDOW
A Creative Application of Graphing of Straight Lines

| A Glass Stained WindowProject |
TOPIC RELATED: GRAPHS OF LINEAR FUNCTIONS
GRADES: 7th - 8th
A colorful and interesting way to end to our Graphing Straight Lines chapter is a project that requires students to choose at least 12 equations of straight lines, give 3 pairs of coordinates and plot them to create an exciting mixture of intersecting lines that will produce sections. Each section will then be coloured to achieve a stained-glass window effect.
STEP 1:
Choose at least 3 equations from each group.
The first group of lines are vertical lines while the second group of lines
are horizontal lines. The third and fourth group of lines are inclined lines
as they already have gradient values, either inclined upwards or
downwards to the right.
STEP 2:
Write 3 ordered pairs for each chosen.
Complete the table of values by assigning a value of x and then solve for
the corresponding value of y.
Although only 2 ordered pairs are needed to form/draw a straight line,
it is advisable to have a third pair to make it more accurate.
STEP 3:
Locate the 3 ordered pairs for each line and connect them to form
the straight line. Do the same to the rest of the lines.
STEP 4:
Colour each section as planned to have the broken/stained glass effect.
[I recommend to use darker marker in making the straight lines.]
To make your own Stained-Glass window in your class, follow the steps below:
STEP 1:
Choose at least 3 equations from each group.
The first group of lines are vertical lines while the second group of lines
are horizontal lines. The third and fourth group of lines are inclined lines
as they already have gradient values, either inclined upwards or
downwards to the right.
STEP 2:
Write 3 ordered pairs for each chosen.
Complete the table of values by assigning a value of x and then solve for
the corresponding value of y.
Although only 2 ordered pairs are needed to form/draw a straight line,
it is advisable to have a third pair to make it more accurate.
STEP 3:
Locate the 3 ordered pairs for each line and connect them to form
the straight line. Do the same to the rest of the lines.
STEP 4:
Colour each section as planned to have the broken/stained glass effect.
[I recommend to use darker marker in making the straight lines.]
Here are some of the projects submitted by my students using different colouring media.
Coloured pens also gave great results, but Extra care must be given when using this medium as the strokes will affect the design.
Water-based paints when used as media also give this magnificent effects.
When all given 30 equations of lines are graphed, the sections made by the intersecting lines become smaller and can become more colourful and stunning stained-window effect, especially if planned very well. An ordinary colouring material may be used.
