to An assessment will be given over the material in this packet in your Honors Geometry class at the beginning of the 2017-2018 school year. Dear Future Honors Geometry Student, Congratulations! You have completed Advanced Algebra 1 as well as earned 1.0 credit toward your 4.0 credits of high school math. We have learned a lot of new concepts this year and it is very important that you retain these skills. Next year you will be taking Honors Geometry. Believe it or not, Honors Geometry uses a lot of algebra skills. Also, Algebra 2 w/ Trig and Honors Algebra 2 w/ Trig will be a lot easier if you keep your Algebra 1 skills up-to-date. This packet contains necessary Algebra 1 concepts that should be practiced. An assessment will be given over the material in this packet in your Honors Geometry class at the beginning of the school year. This packet is meant to assist you in preparing for the quiz. You are free to pick and choose which problems you feel that you need to work on, but we suggest that you do all of them and check your answers. Good luck and have a great summer!
