Here is another set of QR codes I use in my Kindergarten classroom.

This is how I use my QR codes...on a QR word wall placed low enough for my students to use.

I love sharing ideas with others.  I made these QR codes for my students.  It lets them connect to clips I use in teaching my lesson.  You could cut these apart and make a QRcode A-Z wall that is accessible or low enough for them, or clip them together on a ring.
