1. Topic Of Lesson Plan

Applying the Pythagorean Theorem to find distances on the coordinate
plane. 


2. Lesson Content

Pythagorean Theorem
origin
xcoordinate, ycoordinate
quadrants 


3. Goals And Expectations

1) MG3.2 Students will understand how to plot simple figures on
a coordinate plane and determine the length of their sides.
2) MG3.3 Students will know and understand the Pythagorean Theorem
and can apply it to find the length of a missing side of a right triangle.



4. Objectives

1) To utilize the Pythagorean Theorem to find the distance between
two points on a coordinate plane
2) To increase study and interpersonal skills by practicing problem
solving in pairs and small peer groups. 


5. Materials and Aids

1) Handout(s): Ch 3 Quiz 4
2) Materials: whiteboards, markers, erasers, scratch paper 


6. Methods Used and Procedures

A. Introduction
1) Staple and turn in weekly packet.
2) Mental Mathsquares and square roots
3) If you buy a 32in. TV what does that mean? 


B. Development
1) Plot the ordered pairs (2,3) and (5,6)
2) Review vocabcoordinate plane, origin, xcoordinate, ycoordinate,
quadrants
3) Connect the 2 points and make a right triangle. Label the legs
of the triangle (a) and (b) then apply to the Pythagorean theorem. 


C. Practice
1) Draw a right triangle (4,3) and (1,1)
2) Pairs one student uses whiteboard for drawing right triangle and
the other applies the Pythagorean Theorem to find the distance between
the 2 points.
3) Switch  (3,2) and(0,4)
4) If time word problem (6,6) and (1,1) 


D. Independent Practice

E. Accommodations For Students
1) Levels Majority of students are Proficient
2) Strategies Direct Instruction, Cooperative Learning groups,



F. Checking for understanding
1) Same as Independent Practice  Ch 3 Quiz 4



G. Closure
1) On board On the back of your Quiz answer our opening question
in your own words. "What does it mean if you purchase a 32In TV?



7. Evaluation

1. 75% of the students will score 80% or above (4 out of 5) on Ch
3 Quiz 4.
