Don't you hate to spend hours upon hours writing comments on student essays only to have a student say, "I can't read your writing"? If your students have access to an iPad or other mobile device with a Quick Response Reader app, they can scan the QR codes that correspond to the numbers you have written on their papers. An explanation of the errors made by the student will appear on the mobile device, or a positive comment will appear for a job well done. This product includes three parts: a sheet of 20 codes for common essay errors, a packet of 60 codes for more advanced students, and 20 audio codes for all ages. The students will get a kick out of hearing a computer voice tell them, "You have done a wonderful job on this essay!" So save yourself hours of grading by using this fun product.
