Activity of text interpretation, aimed at students in the sixth year of elementary school, on the QR code. QR codes (in English, Quick Response, or "Quick Response" in Portuguese) are part of the family of two-dimensional bar codes, that is, capable of storing more information, such as digits and letters. Shall we find out more about this code? To do this, carefully read the text “How does the QR code work?” Then answer the various interpretative questions proposed!
This reading comprehension activity is available for download in an editable Word template, ready to print to PDF, as well as the completed activity.

You may have seen small black and white drawings found in many products, such as magazines, books, toy packaging and more! No, it's not the old familiar barcode. In fact, it's his “cousin”, the QR code.
QR codes (in English, Quick Response, or "Quick Response" in Portuguese) are part of the family of two-dimensional bar codes, that is, capable of storing more information, such as digits and letters. Instead of dark and light bars alternating next to each other, in the QR code there are small dark and light squares arranged in a larger square. In three corners of this region is a patterned design that is used by QR code readers to quickly decode information.
To read the information stored in the QR code, you must have a cell phone with a special program for reading these codes. Only with this app, the message stored in the picture can be deciphered.
When a cell phone with a QR code reader is pointed at the picture, the device is able to scan the picture and decipher the code. With this action, what was stored soon appears on the device screen, such as email addresses, web pages and contact information. If it is a virtual mailbox, for example, a new message window can be opened; if it is a website, you can visit it or have access to the audio of a book to hear the story, buy products, among many other actions.
There are free apps for both reading and generating these codes available on the net. But beware: it is important to always have the authorization of those responsible to decipher or create QR codes, ok?!
