Algebra 1 Review for Placement Test

advertisement
Dear Future Algebra 2 Student,
We, your future teaches, desire for you to have a successful Algebra II experience. The Algebra II
Honors curriculum is rigorous, beginning with advanced skills such as graphing quadratic equations
as well as solving quadratics by factoring. These topics will be approached with the assumption you
have mastered the prerequisite skills learned in Algebra I and Geometry.
Your success is Algebra 2 will largely be dependent on your Algebra 1 and Geometry foundation and
your willingness to go above and beyond when the material is difficult.
In order to make sure you are properly placed next year you will need to take an Algebra 2 Honors
placement test. To prepare make sure to do the attached question set. The answers can be found
online at www.mrsstillman.com under the “Algebra I Review Assignment” tab.
You will take the placement exam in class on Thursday January 7, 2016. ALL students who desire to
enroll in Algebra 2 Honors next year MUST TAKE THE PLACEMENT EXAM!
If you have any questions, comments, or concerns email Jessica.stillman@browardschools.com.
