For this activity, students are given a worksheet with a table. One column says code number, one column says "h-time" and the other says "word time". Then, they will use mobile devices to scan QR codes that you can place around the room. Upon scanning, a link to a tinypic url pops up. When they go to the url, they see a picture of a clock face. Each code has a number associated. For example, if they scan code 20 and see 1:15, they need to write "1h15" in the h-time column and "une heure et quart" in the "word time" column. There are 20 codes in all. Finally, when the activity is finished, you can go through the answers using an included powerpoint. Each slide first shows the clock they saw, then upon the click, they can see the answers (this powerpoint also works great on its own for whiteboard practice! double whammy!).
The answers are in French, but as the clocks are universal, this could really work for any language: Spanish, German, Japanese, you name it!
