This document includes 4 pages with 2 words per page for a total of 8 word wall items. Each word contains a QR code that when scanned gives a definition for the word above the code.
I use these as part of my interactive word wall; however, these could also be used for review or even to have student take notes over these words. Students are usually fairly invested in these types of activities because they get to use their device as part of the assignment. Makes academic vocabulary more interesting and engaging.
