The document outlines a lesson plan for a 2nd grade class. It involves having students create QR codes containing multiplication and division problems. There are 21 students total, with 13 girls and 8 boys. Students will create their own QR codes using an online creator. They will then post the QR codes to the class Twitter page. As homework, students will solve all the QR code math problems posted by their classmates and bring their answers to class on Monday to be evaluated for accuracy.
