Algebra Summer Review Packet Welcome to Algebra! Attached you will find the learning targets your teacher thinks you should know BEFORE you come to class in the fall and problems to help you practice these targets. The answers and worked out solutions to these questions are included to help you review the material. This material must be mastered and you will be assessed in the first week of school. Use the following sites and QR codes in this review to help with any of the learning targets you struggle with. http://www.wolframalpha.com/ http://www.khanacademy.com/ We are looking forward to seeing you in the fall!
