Summer Assignment for students ENTERING: Algebra 2 Trigonometry Honors

Please have the following worksheets completed and ready to be handed in on the first day of class, August 12, 2019. Make sure you show your work where appropriate. Answers are provided for you to check at the end of this packet; however, you will not be given credit if you don’t show work on problems that require it. Please neatly organize your work, show all of your work, and place all of your work and answers ON these worksheets. It is expected that you have a good understanding of this material coming into Algebra 2 Trigonometry Honors, as teachers will not be doing an extensive review of previously learned material. Have a great summer and we look forward to seeing you in the fall!
