Cherry Creek High School Summer Assignment for students entering: Accelerated CP Geometry Please have the following worksheets completed and ready to be handed in on the first day of class in the fall. Make sure you show your work where appropriate. Answers are provided for you to check; however, you will not be given credit if you don t show work on problems that require it. Please neatly organize your work and use notebook paper when there is not enough room to show all of your work on these worksheets. It is epected that you have a good understanding of this material coming into this class, as teachers will not be doing an etensive review of previously learned material. Have a great summer and we look forward to seeing you in the fall! The CCHS Math Department
