This QR unit is used to introduce students to a new unit, in this case OA for 5th grade. Students absolutely love making a "mystery" QR code. This is used as a challenge to see which student can find the best resource for the upcoming topics for the unit. Students then bring in their qr codes, I number the codes, and the students walk around and critique each others resources on the included graphic organizer. When done, students rank and vote for their favorite resource. I then use the QR codes to display a helpful resources bulletin board for the students to use throughout the unit. A great way to get students excited about a unit, and engages 21st century learners with technology!
