Essential Questions:
How does simplifying rational expressions relate to the original rules you learned for fractions in
middle school?
Why do we have to exclude certain values from the denominator?
In science, if we cancel out infinities, why does that help us get ahead?
Modifications/Accommodations: What curriculum modifications and classroom accommodations will you
make for Students with Disabilities in your class?
Extended time for completion of assignments or tests.
Additional time for reading assignments.
Time for repeated drill and review.

Common Core Aligned Lesson:
Reflection
+ It is important to connect this lesson to science since canceling out infinite and unknown values in one of the best
ways that we get real rational answers in scientific research.
- Again, both classes were weak in recognizing the difference of squares and factoring expressions.
