The students are learning vocabulary words. Research tells us that they learn these words and their meanings better if they also have visual and kinesthetic clues to help them. Here is a lovely visual example of some of the words and what the students are doing to be sure and remember them.
Students: Please remember that we make these videos and digital products to help make learning fun. They are not created for the sole purpose of entertainment. It's okay to enjoy watching them and to be entertained, but the primary purpose for watching the video should be to help you learn. -Mr. PahlSchoolTube - Vocabulary Words
