This product contains 36 worksheets. Each worksheet has 4 QR Codes to be used with a QR reader app. Each worksheet has an episode of Cliff Hanger, phonics video, lyric video, and sight word video. Each page has a new Cliff Hanger episode and phonics video. The lyric video repeats after week 19. There are only 3 sight word videos which repeat every three weeks. All videos come without commercials. You can choose to use all four QR videos or you can cut out the ones you want for your students. Each section comes with a basic assignment along with a challenge assignment. Note I do not own the videos, only the QR codes. You will need to download a QR Reader on your device. Please make sure you are able to scan and use the QR codes in the preview before you purchase.
