Have you seen Plickers.com and its app yet? They are awesome and FREE! They are high-tech low-tech pinch cards, a clicker system that only needs one device. Your iPad or Android device will take a picture of your students' answers and hold the data online. If you pay for the laminated cards, they come ready to go for you and on the back is the Plickers logo. Great, but not so helpful for little kids. I have designed the back of the small Plickers cards to have both student numbers (in the center) and a key for students to see as they are using them which letter is up, down, right, and left - you get to see the front side to take the picture. I hope you enjoy these cards and enjoy the website - plickers.com! Print these double-sided on cardstock and laminate. I don't know where to get a matte laminate material, we only have shiny at my school, so try laminating two at time with the picture side together and only having one side laminated for easier photo-taking (less glare). By the way, they updated the website and it is AWESOME. Please try them out!!
