Tech, Tac, Toe  - QR codes

           A  QR code consists of black modules (square dots) arranged in a square grid on a white background, which can be read by an imaging device (such as a camera) and processed using Reed–Solomon error correction until the image can be appropriately interpreted; data is then extracted from patterns present in both horizontal and vertical components of the image.

 QR codes now are used in a much broader context, including both commercial tracking applications and convenience-oriented applications aimed at mobile phone users (termed mobile tagging). QR codes may be used to display text to the user, to add a vCard contact to the user's device, to open a Uniform Resource Identifier (URI), or to compose an e-mail or text message. Users can generate and print their own QR codes for others to scan and use by visiting one of several paid and free QR code generating sites or apps. It has since become one of the most-used types of two-dimensional barcode.

WR codes can be read by downloading applications that are compatible with different devices such as ipads, iphones, androids, etc. When you take a picture of the code, it will take you to a URL, text, or a specific sms message.

    Throughout the week, children have been learning all about frogs; their natural habitat, life cycle, and other facts about frogs. At the end of the week, we will review what we have learned so far and some questions we still might have.

 I chose to use QR codes to review our theme. I will write down a question on a flash card with a picture of a QR code next to it. The children will have the opportunity to compare their answers with the answers provided through the QR codes!!

Example:

Where are the gills
when the tadpole first hatches?   

 

                     What do tadpoles eat?
