Daily Lesson Plan
Sin, Cos, and Tan.
II. Organization: Whole Group
-Students will copy the
formulas and examples that might help them with their homework and test. Students
will also work individually on some problems to make sure the children understand the topic
III. Objectives: - Students will demonstrate be able to locate the legs,
and the hypotenuse on a right triangle.
Students will do problems based on what they learned in class to demonstrate their knowledge of the topic.
will be able to solve Sin, Cos, and Tan, functions in their calculators, and give their measurements.
Standards Covered: 2.10
- Identify right
angles in the environment.
- Identify and
compare parts of right triangles, including right angles, acute angles, hypotenuses and legs.
- Compute measures
of sides and angles using proportions, the Pythagorean Theorem and right triangle relationships.
- Solve problems
requiring indirect measurement for lengths of sides of triangles.
create and solve practical problems involving right triangles using the trigonometric functions and the Pythagorean Theorem.
- Textbooks (for problems in the chapter)
-Overhead projector or white board to write important
formulas and examples for the students to understand.
VII. Procedure: Intro/Motivation- My
intro will be to show students some formulas for Sin, Cos, and Tan. Especially,
SOH, CAH, TOA. It will explain this formula, and how they can use this to get
angle measurements and lengths of the legs or hypotenuse. After showing students
how to use this formula, I will show the students how to use the calculator to solve some of the problems to do with this
- The motivation that I will use is to again give out the triangles that I gave out
in the Pythagorean lesson and show students other ways to find measurements of sides and angles. I will split the class up into groups and allow students to interact with each other describing and explaining
to their group members how they arrived at the answer.
Activities- Depending on how the students grasp this topic, I will have an activity
like Jeopardy or Hollywood Squares where students have the opportunity to gain extra point for their test. I will give problems based on the homework and the team that has the most points will get a certain amount
of points on their test.
VII. Closure:- To close the class, I will briefly summarize what we have learned
in class, and I will go over a couple of the homework problems so the students will understand them for homework. Students will have the opportunity to ask me questions about the lesson if they need to. I will also emphasize if the homework is not completed they will get a miss for the homework and it will
lower their grade.
VIII. Adaptations- For those with special needs, I will give out sheets with the formulas that I given
in class with a couple of examples of how to do them. I will also help them after
class if the need some extra help. The next day I will check their homework and
correct them if necessary. If they understand the problems, I will allow a couple
of them to go to the board and do an assigned homework problem.
IX. Evaluation- Student- I feel
that the students will be able to do the assigned problems with the homework cause I will be spending a good amount of time
on some examples so the homework shouldn’t be a problem.
Teacher- The topic is slightly hard to understand, but if I go over the formula enough and
do some problems pertained to the formula then students should be able to grasp the topic and complete the homework problems.
Follow- up- A follow up lesson will be to teach the students how to do Sin, Cos, and Tan functions.
XI Assessment: To check on the students progress on this topic, I will have
a quiz at the end of the class the summarized some examples I addressed in class or I will ask certain group members to get
up and explain how they arrived at the answer to the class so not only will the group member understand what their explaining,
but hopefully other classmates will understand how the group arrived at the answer.
