Read and Think about the following statistics. Then, answer the questions
10% of students in low-income communities who decide to go to college
actually graduate from college.
50% of students in low-income communities will not graduate from high
school by the time they're 18 years old.
Considering the fact that Morrow High School is located in what the state
determines to be a low-income community, how do these statistics make
you feel? What will you do for the remainder of this year to ensure that as
a student in a low-income community, you will not be another statistic?
Now that you have just taken your unit 1 test, what specifically will you do
in this class from this point forward to ensure that you will not be another

notions of point, line, distance along a line,
and distance around a circular arc.
Students Will Be Able to…
• Define angle, circle, perpendicular line,
parallel line, and line segment.
• Understand the concept of point, line, and
distance along a line and around a circular arc.

• Points are said to be collinear if they lie on a
single straight line. P1, P2, and P3 would be
said to be collinear.
A line that has one endpoint and continues on forever in
the opposite direction.
