Introduce, practice, and/or review kindergarten high frequency/sight words with these QR code cards. Scan the blue codes (in black frames) to see the words; scan the black codes (in green frames) to HEAR the words. Animals help students match the word codes to their corresponding voice/sound codes. A great center activity to help your students independently learn those kindergarten high frequency words. NOTE: Need to use a QR code reader that will read voice codes. I-Nigma is one code you can use.
