Engage
Students who were absent
Friday will be given the test to
make up. Students who were
not absent will be told to
quietly work on their
classwork.
Engage
The angles of the unit circle will
be reviewed. The circle will be
drawn on the board and the
students will be required to
respond with the angles in
degrees and radians.
Engage
Students will be asked what to
do when the angle is obtuse
and a right triangle could not
be produced by starting at the
positive x-axis.
Engage
The second quadrant will be
reviewed. The unit circle will
be drawn on the board and the
known values will be filled in.
Engage
The third quadrant will be
reviewed. The unit circle will
be drawn on the board and the
known values will be filled
in.
Explore
Students will be given an
assignment to work on during
class. The assignment will
include real-world applications
of sine, cosine, and tangent.
Explore
Students will be given the unit
circle worksheet and asked to fill
in the angles. Students will also
be given paper triangles to place
on the unit circle to determine
the reference angles for a given
angle. Students will be given
rules (one acute angle must start
at the origin and the right angle
must lie on the x-axis) and told
to find which triangle’s
hypotenuse lines up with the
terminal side of the requested
angle.
Explore
A PowerPoint will be shown
depicting the placement of
right triangles in the second
quadrant of the unit circle. The
students will then be asked to
use special right triangles to
find the remaining side lengths
and then find the sine, cosine,
and tangent of the angle.
Reference angles will be
reviewed for the second
quadrant.
Explore
A PowerPoint will be shown
depicting the placement of
right triangles in the third
quadrant of the unit circle.
The students will then be
asked to use special right
triangles to find the remaining
side lengths and then find the
sine, cosine, and tangent of
the angle. Reference angles
will be reviewed for the third
quadrant.
Explore
A PowerPoint will be shown
depicting the placement of
right triangles in the fourth
quadrant of the unit circle.
The students will then be
asked to use special right
triangles to find the remaining
side lengths and then find the
sine, cosine, and tangent of
the angle. Reference angles
will be reviewed for the
fourth quadrant.

Since so many students will be
making up Friday’s test, an
explanation will not be
conducted verbally.
Elaborate
If all of the students finish
before class ends, the class can
begin discussing sine, cosine,
Explain
and tangent in other quadrants.
The students will be given a
chart and asked to record the
values they found. The students
will be called up to record the
values on the board. The
students will then compare their
chart to the class chart.
Elaborate
The class will discuss how the
reference angle can be calculated
for each quadrant.
N
Resources:
reference angle of an angle and
how this could be used to draw
a triangle and then find the
sine, cosine, and tangent of the
angle. The students will record
their new point values on the
unit circle and the trig chart
from the previous day.
