Our school district has rolled out iPads to all students in grades 3-5 (and Dell Venue 11 Tablets with detachable keyboards to students in grades 6-12). This has kept us (all the tech coaches) BUSY this year!
One thing I am trying to do is incorporate the use of iPads with the notebooks. One web tool I use a lot is bingobaker.com . It is free bingo game card generator that you can either print out or play using your tablet.
For students I created a QR code (using QRstuff.com) and put it at the bottom of their science vocabulary sheet that goes in their notebook (see second picture). When we are ready to play students take out their iPad, scan the code and it goes straight to a randomized bingo board (no two bingo boards are the same). Students touch the screen to make the square light up and touch it again to make it go back if they made a mistake. Once a winner has been declared students touch the "refresh" circle and they get a new randomized board.
The game is VERY popular with students. Just make sure you have some prizes on hand!
