I haven't used a listening center very much this year, but
I had the recording equipment (CD/tape player), and 4 or 5
headphones plugged into a junction box (which connected to
the CD/tape player). Because I didn't have a spare table
for the LC, I located it on the bottom of my stereo's cart
and the kids just sat on the floor with the books. When
they were done, they went back to their seat to complete
the 2nd part, which was usually to draw a picture of their
favorite part of the story.
Our district purchased subscriptions to both RAZ-Kids
(Reading A-Z) and Imagine Learning. So now, those two have
taken their place in my language arts daily 5 rotation.
Imagine Learning went where the LC was. RAZ-Kids is the
electronics word work. (My rotations, usually 2-3/day,
include small group instruction with me, seatwork, RAZ-
Kids, paper word work, writing center, and Imagine
As for QR codes -- I use them for sight words. I found some
Sight Word QR code packets on TPT, mounted them on
construction paper, copied the paper lists, and now that is
one of the paper Word Work Centers. My kids access the
codes through old iPod Touches. If they finish a list, I
give them a sticker. They get another sticker (or two) if
they can read me the sight word list!
I have not used QR codes for listening centers, so I can't
help you there.
