2. Analyzing the Learners
General Characteristics:
oThe students for whom this lesson is intended are high school students who are taking
geometry. The students are around the age of 14 and 15. There are 11 girls and 14 boys in the
class and a variety of races among them; 60% white, 25% African-American, and 15% Hispanic.
Learning Styles:
oAll students learn differently so I need to incorporate visual, auditory, and hands on types of
learning.
Specific Entry Competencies:
oBefore teaching the students, I need to find out what they know and what they do not know
about trigonometric functions of right triangles. I do not want to assume that they know more
or less on the subject. I will do this by testing them the week before on a small pop quiz.
3. Main Objective
oGiven a triangle’s side and/or degree measurements, the students will be able to explain and
demonstrate how to find the values of trigonometric functions and how they can be used to
solve right and non right triangles after watching videos, listening to podcasts, doing webquests,
reviewing posters, doing homework assignments using twitter, Facebook and blogs, working in
groups to complete practice problems, and making their own life applicable problems using one
of the technology tools presented, by the end of the week, with 85% of accuracy.
4. Day-By-Day Breakdown
Day 1: Define and apply the trigonometric functions using SOH-CAH-TOA (sinA =
opposite/hypotenuse, cosA = adjacent/hypotenuse, tanA = opposite/adjacent) and cosecant,
secant, and cotangent (cscA = hypotenuse/opposite, secA = hypotenuse/adjacent, cotA =
adjacent/hypotenuse).
Day 2: Solving right triangles using the trig identities.
Day 3: Define and apply Law of Sine and Law of Cosine.
Day 4: Solving right and non-right triangles using Law of Sines and Law of Cosines and the trig
identities.
Day 5: To asses the students, they will create their own problems and solve them. How they
decide to solve it and turn will be their choice. They must present their problem and solve it
using one of the technology tools that I used over the week to teach them. They will begin it in
class and turn it in first thing the following week.
