Crazy Triangles
6th Grade
Project:
Students will use a ruler to cut out several right triangles
of all colors and sizes. They will then glue each triangle to their paper one
at a time, finding areas along the way, creating rectangles and squares or just
using the triangles. Creating a colorful collage of triangles, squares and
rectangles.
Materials:
·
Rulers
·
Colored construction paper
·
Scissors
·
Glue
·
Markers or Crayons
Objectives:
At the end of this lesson students will…
·
Find the area of triangles, rectangles and
squares.
·
Experiment with non-representational art.
·
Experiment with the many uses of rulers.
Visual Arts
Standards:
Combine concepts collaboratively to generate innovative
ideas for creating art.
Formulate an artistic investigation of personally relevant
content for creating art.
Other Standards
(Math):
Use a pair of perpendicular number lines, called axes, to
define a coordinate system, with the intersection of the lines (the origin)
arranged to coincide with the 0 on each line and a given point in the plane
located by using an ordered pair of numbers, called its coordinates.
Understand
that the first number indicates how far to travel from the origin in the
direction of one axis, and the second number indicates how far to travel in the
direction of the second axis, with the convention that the names of the two
axes and the coordinates correspond (e.g., x-axis and x-coordinate, y-axis
and y-coordinate).
Vocabulary:
·
Right Triangle: A triangle with one 90 degree
angle.
·
Rectangle: Any quadrilateral with four right
angles
o
Quadrilateral: four sided polygon with four
angles.
·
Area: the amount of space within a 2-Dimensional
figure.
·
Square: A polygon with four equal sides and four
right angles
o
Right angle: two lines meeting at 90 degrees
·
Area of a right triangle = Leg a X Leg b / 2
·
Non-representational Art: Art that doesn’t look
like anything from the “real world”.
Pedagogy:
15-20 min – Introduction
·
Explain what a right triangle is
o
A triangle with one right angle
o
A right angle is 90 degrees
·
Explain how to find the area of a right triangle
o
Area: the amount of space within a 2-D figure.
o
Area of a right triangle = Side a X Side b / 2
·
Pass out a quick worksheet with several
different sized right triangles.
o
Have the students complete the worksheet,
raising their hand if they need help.
5-10 min – Create the Triangles
·
Call the students up one by one (those sitting
quietly) to pick up to 4 different colors of paper
·
Pick four quiet students to pass out the rulers
and scissors.
o
As they are doing this demonstrate how to cut
out/ make various sized right triangles.
·
Have the students cut out their triangles with
their colored paper.
o
No more than twenty triangles (too many will be
overwhelming and they wont have time to finish)
25-30 min – Art time
·
Pass out a large white piece of paper and glue
to each student.
·
Explain the project to the students
o
Glue your triangles on your paper in any pattern
or style you want.
o
As you glue the triangles on, on a separate
sheet of paper figure out the areas of each.
§
Using the ruler measure the sides in cm to use
as the side lengths
·
Explain Non-Representational Art
o
Art that doesn’t look like anything from the
“real world”.
o
Have the students place their triangles on the
paper in a way that doesn’t look like any real thing.
·
Walk around and help the students as needed.
5-10 min – Clean up time
Assessment:
For this assignment I would have a summative assessment the
next day with a short quiz to see if I needed to spend more time on right
triangles or move on.
