Formatives and QR Codes

We are currently sharing iPADS in our elementary classrooms. Each grade level shares a iPAD cart. We will be getting chromebook carts to use as well. For our K, 1, 2 grade students, any ideas aside from QR codes on how to utilize in class increasing instructional time? We do not want to waste a lot of time having our little guys and gals logging in, typing in websites.


I use a lot of QR codes in my teaching. Like, I create question paper QR code and also answersQR code. For early education in math class you can probably give them question and put a QR code next to each question for checking their answers. Or even put a QR coded video and ask students foe different activities etc.
