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