Intro to NM
Quick Review:
What is an equation?
How do you solve an equation?
What is a system of equations?
How do you solve a system of equations?
Notebooks – graphing calculator lab
Model the example, then have them complete in partners


Key questions to ask during GP: (Question Script)



IP 1
Students complete page 259 in partners


Intro to NM
Lesson 62 – word problem application
When you read this problem, what do you notice first? Anything different?
What information are we given? What two situations are presented here?
How can we translate this into an algebraic statement?
Let students try to write equations, then poll for answers – which is correct? How can we check?
Then have students make the graph on their own – then use the graph to answer the questions.


Key questions to ask during GP: (Question Script)
Which graph is steeper? Why? What does that tell us about the problem?
Why does one graph start higher than the other?
What does the intersection represent?


Key questions to check for understanding before IP (Last three questions you will ask)
Independent Practice Activity:
Students complete packet (Coach testprep, Kuta graphing practice, and word problem applications)


Closure: How will you close the lesson?
Share out answers from IP
Exit ticket

Assessment: How will you assess mastery of the objective?


Homework

Anticipated Challenges

Reflection: I had to take out the IP for the graphing calculator lab, but you can probably make a few practice problems pretty easily.
