This is a 20+ page PDF that has active links within the PDF that will take you to either my YouTube videos explaining the various command types or they will also take you to different places within the PDF. While the videos are always free to view on YouTube, this PDF also has dozens of practice activities along with the answers as well. This could be useful if you want to use the activities to make quizzes / tests. Or maybe you had a student that missed a few days of instruction and you just want to get them caught back up. They could sit down with this PDF, you could point them to a page and send them on their way.
