Algebra 1 1st Quarter Problem Sets 2015 – 2016 Problem sets are due according to the schedule below. You may work together on problem sets, or you may come in early before school and ask the teacher for help. Use your textbook and notes to help you. ALL WORK MUST BE SHOWN, or you will receive no credit! Students are not allowed to ask for help on the day the problem set is due!!! Students also must have work to show the teacher before asking for help (show that you tried). The primary purpose of the problem sets is to reinforce the spiral approach of mathematics, reviewing material learned last year, last month, last week, and to prepare for the upcoming SOL. You may turn in problem sets early for 2 points extra credit! Early means at least 1 day early. So if a problem set is due Thursday, turning it in Tuesday or Wednesday would give you 2 points extra credit! 7 No extra credit will be given if you do not score . Check your answers – accuracy is VERY 10 important! You may make corrections and turn in problem sets for a re-grade, but all work MUST be shown. Scores may increase to the maximum of 80%. There is a one-week time limit for redos on problem sets from the time the problem set is passed back. Problem Due Dates Set # A Day 1 (Only for those who Wednesday, September 9th did not turn in Summer Assignment) Due Dates B Day Thursday, September 10th 2 Monday, September 21st Tuesday, September 22nd 3 Monday, October 5th Tuesday, October 6th 4 Tuesday, October 20th Wednesday, October 21st REMEMBER – Problem sets are due at the beginning of class!
