This bundle on Spanish Stem Changing Verbs includes a 36 slide PowerPoint, a guided notes handout with additional practice, and 2 additional handouts that can be used for a day you have a substitute, remediation, or if you feel your students need more practice. I also turned the PowerPoint into a video that I've uploaded to YouTube. It's a great way for absent students to get an understanding of the concept, or as review material for students who need to retake an assessment.
