These 24 task cards can be used to review the concepts for the PARRC exam.  This set comes with a full set of answers/solutions and sheets of QR codes that students can use to self check their answers.  The QR codes are printed on separate cards so the teacher is in control as to when a student has access to the codes.  Check these out in my store at Teachers Pay Teachers.  https://www.teacherspayteachers.com/Product/High-School-Geometry-Task-Cards-3729926

This set of task cards has recently been updated and now includes two identical sets of cards.  One set has the QR codes on the card and the other set of identical questions have no QR codes.  An activity can be made that includes some QR codes and other cards that do not have QR codes.  Full solutions are included for all cards.
