1. Topic Of Lesson Plan-
Applying the Pythagorean Theorem to find distances on the coordinate plane.
2. Lesson Content-
Pythagorean Theorem
x-coordinate, y-coordinate
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 Math-squares 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 vocab-coordinate plane, origin, x-coordinate, y-coordinate, 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-

1) Ch 3 Quiz 4

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.
