2. What are QR Codes?
QR codes are much like bar codes in that they
contain information and can be scanned. Bar
codes only contain information from left to right
but a QR code can contain information from left
to right or up and down.
A QR codes work much like bar codes in that it
can be scanned and linked to a set of data.
Unlike bar codes, QR codes can pack much
more information into a smaller space - up to
4,000 characters

5. What can you use if you do not have a
mobile device to read the QR Code?
If you do not have a mobile device students can use to read a QR code, you can
still have them read the codes using an extension in Google Chrome called
QRreader beta. This extension allows you from your Chrome browser to right
click on QR code and decode the QR.
The QR code can be a part of a web site
or in a Google Document. When students
right click on the image, this is what they
will see. Select "Read QR code from
image" and it will decode the QR for
the user.

6. Add a Voice to the QR code
When using the web site qrvoicce.net you are
able to enter up to a 100 character message
that when decoded will be read by a
synthesized voice.
You can either type in the message or say the
message through a microphone.

7. Create a QR Code in a
Spreadsheet
1. In Google Docs open up a new spreadsheet.
2. In Column A, type Web or Url
3. In Column B, type QR Code
4. Resize the row to 100.
5. Leave the column size alone. (If you want your codes to
appear larger, then resize the row and columns to a
larger number.)
6. In column A type your text or URL that you want your
QR code to read when scanned.
7. In Column B insert this formula:
=image("https://chart.googleapis.com/chart?chs=150x150&cht=qr&chl=" &

8. Remember...
TEST...TEST...TEST
It is important to check your QR codes to make
sure they work, even if they worked the first
time you use them test them regularly to
make sure they urls are still good or that the
codes have not become "damaged."

9. Ways My School Has
Used QR codes in the
Classroom

10. Classroom Incentives
Create classroom incentives for students.
Examples: homework pass, tablet time, extra
points on a quiz, etc.

11. Vocabulary / Word Wall
Create a word wall for the classroom. Post the
vocabulary word up and students can scan
the code for whatever information you want
them to learn. Also, you can use codes to
create flash cards.

12. Assessments, and Exit Slips
Provide students with a code for them to scan.
It will take them to a Google Form created to
survey or assess their understanding of the
lesson.

13. Self Assessment
Insert a QR code to
a worksheet and
have students
check their work.

15. Make Wall Displays More
Interactive
Make posters and bulletin board displays more
interactive by adding codes to allow students
and visitors a way of getting more
information about the topic being displayed.

16. Differentiation
QR codes are a great way to differentiate a
classroom activity without calling attention
to the level of questioning you might ask of
different groups of students.
Example: Pin QR codes to
physical models and have
students answer their questions.
Different groups could have
similar models, but answer
completely different questions.

17. Collecting Commonly Used
Websites
QR codes are one way of collecting commonly
used sites for students to scan. QR codes are
a nice way to ensure students are getting to
the exact site you want them to get to without
getting lost because of misspellings or
mistypes. Keep the codes in an 3 x 5 index
cards and store on a ring or in a box.

18. Create Book Talks
Attaching QR codes to text can allow students
additional ways to preview novels and enrich
novel studies.

19. Posters or Advertising School
Events
Creating a QR code on a poster is one way to
advertise a school event and to link people to
more information than you were able put on
the poster.
