Last week fourth grade found a fun activity that used a math word problem on a notecard.
Start with a problem (I’m going to grab a sample test item from a test generation site that you might want to consider as a resource)
An example test item from http://my.triand.com/
Under the problem post a QR code and a short URL (web address) to the answer.
In this way the student can use a phone, iPad, or netbook to look up the correct answer.
I took the screenshot of the question and put boxes around the answer using skitch. https://evernote.com/skitch/
I used http://imgur.com/ to host the answer image. (it’s free)
I used an extension in Google Chrome to make the QR code and short URL.
