Struggling to meet the demands of the academic vocabulary of the Common Core? Have students scan this AR trigger with the app LAYAR. It will take them to a Tellagami which asks them to make a vocab box in a screencasting app and draw visual representations of four different vocabulary words. I find that this activity helps the students connect the through-lines of the of the Algebra 1 course. Perhaps this activity will be useful to you in your learning environment.
