6. Procedures/Methods-
|
A. Introduction-
1. DO NOW.
x = 1x, T/F?
x = x/1, T/F?
And review.
2. We're going to learn how to graph the slope of a line, and to simplify
our inequalities so that they are in a format that we can graph.
3. We'll start with a question. What would it mean if you said "Ms.
L, I'm going to get AT LEAST a 95 in your class". What other grades
might you get in my class if you're going to get AT LEAST a 95?

B. Development-
1.When you hear or read words like AT LEAST, or AT MOST, these vocabulary
words signal that we can write an inequality and graph it's slope.
Take one minute to write out what that would look like in the following
format: Y is blank than 95 if Y is the score that you are going to
get in my class.
Refer to the key on the board for the inequality signs you can use
to say that you're grade will be at least 95.
Please put your pen in the left corner of your desk so I know you're
done and ready to graph it.
2.(walk around the room, see that someone has it, and prime them to
share out).
3. Great, so we have Y is greater than or equal to 95. What other
grades might you get in my class? (share out a couple).
4. OK so let's graph it.
FIRST STEP: to graph this, we need to make this look like the slope,
y-intercept formula. (Ask, does anyone remember what the slope, y-intercept
formula looks like? and provide it if not.)
STEP 2, identify the y intercept and the slope. Y > 1x + 95.
STEP 3, Agree on scaling. Plot the y intercept. Do you agree? Why
is this the y intercept?
STEP 4, The y intercept is where we start, to know what the slope
looks like on the graph, we need to know how many to count count up
and down on the y axis, and right and left on the x axis. STEP 5 We
need to make the 1 in front of the x a fraction. 1/1.
So count positive 1 on the y axis and negative 1 on the x axis and
plot another point. We'll need to do this a couple times so that we
have enough plots to connect into a line. |

C. Practice-
Another example together, students come to the board and help fill
out each of our steps.
Y > 2x + 6 |
|
|
D. Independent Practice-
Worksheet, I am walking around and helping as needed.

E. Accommodations (Differentiated Instruction)-
1. Key on the board. Vocabulary and inequality signs. Slope, Y-intercept
formula on the board, as well as identity properties of multiplication
and division. There's also m= y/x on the board.
2. Slope Y intercept formula is color coded for each element. We're
using these colors throughout instruction.
3. Worksheet has students complete everything we did step by step.
Problem 1 is make this look like a slope-yintercept formula, problem
2 has them identify the slope, and identify the y intercept. |

F. Closure-
Thank you for your attention. Great job today. Please fill out the
exit slip I've placed on your desk (asks them to circle anything from
today that they were not clear on).
