Content

Simplify and expand algebraic expressions using exponential forms. Complete calculations by applying the order of operations. Develop formulas and procedures for determining measurements. Verify and interpret results using precise mathematical language, notation and representations, including numerical tables and equations, simple algebraic equations and formulas, charts, graphs and diagrams. Determine pertinent information in problem situations and whether any further information is needed for solution.

Benchmarks

The goal of this lesson is for students to be able to calculate the unknown side of a right triangle, given the lengths of the other two sides.

Development of Lesson
Introduction

Make copies of all handouts prior to class
Have answer key prepared for both handouts
Take roll (Report any absentees to the office)
Confirm that there are an adequate number of calculators
Arrange desks so that all students can see the projector screen clearly
Get PowerPoint ready on the computer
Pull down the projector screen
Turn projector on

Methods/Procedures

The students will be able to cooperate with group members during the handout.
* I used the Cognitive Apprenticeship model *
Introduction:
Briefly explain that we are going to be discussing the Pythagorean Theorem. (1-2 min)
Transition: Distribute handouts and give directions to instruct the students on what to do. (2-4 min)
Developmental Activities:

Students can share calculator and resources if it's needed.
The students that grasp the content quicker can help the ones who need a little more help.
There will be hands on, visual, application with handouts, and verbal amongst other students.
Quizzes, tests, and homework will check their understanding of the lesson.
View different methods if the concept was not accepted.

Assessment/Evaluation

The students will be able to describe and define the Pythagorean Theorem when asked from memory.
The students will be able to identify a right triangle and the corresponding sides that fit the Pythagorean Theorem.
The students will be able to recognize the Pythagorean Theorem and read it out loud properly.
The students will be able to identify the difference between the legs and hypotenuse of the right triangle.
Given two sides of the right triangle, the students will be able to solve the Pythagorean Theorem for the missing variable.
The students will be able to define and differentiate between when they are and are not supposed to use the Pythagorean Theorem.

Closure

How was my timing?
Did the students understand the material?
Did I get to cover all the material in my lesson plan?
Am I satisfied with the way I planned the lesson?
