Please have a seat and take some time to look over the notes worksheet. Look at the diagrams, and take a close look at the vocabulary words. If you can use prior knowledge to place any of the vocabulary words on the pyramid diagram, feel free to do so. During the video, listen for any of the vocabulary words listed on your page, and pay close attention to any diagrams explained in the video..
