Mr. Q’s Honors Geometry Christmas Break 2012 Homework! To keep you fit during the off-season and ready for the New Year! All of the questions are multiple choice. At the end of each assessment are the answers. Do NOT look at the answers before completing the assessment. That defeats the entire purpose of this if you do! Complete the assessment on a separate sheet of paper and show your work (if possible), check your answers, highlight which questions you got wrong, and redo those questions on another sheet of paper. If you redo a question and still did NOT get the correct answer, write it down and we’ll go over it in class. It is OK to get questions wrong just as long as you learn from your mistakes! You will have your mom or dad sign this sheet below stating that you completed the assessment, checked your answers, redid the questions you got wrong, and writing the date of completion. Do NOT wait until the night before school starts or even worse the morning of the first day of school to complete this assignment!
