Hello Everyone,

Last week, students in second through third grade worked on a QR (quick response) investigation using iPod touch devices to find the missing hundreds digits to complete the Dewey Decimal numbers for some popular topics.

When they scanned the QR code on a mini poster like this one for computers, they discovered the missing hundreds digit to complete the call number ” ? 04.”

An example of a QR code mini-poster.

Enthusiastically,

Ms. Tyler
