This is a great start of the year assignment, where students get to teach the class something that they are an "expert" in.
The students in the past have used this opportunity to let teachers and new students to the class/school get to know them. This activity is a great way to embrace differences and share similarities. Students love to share things that they are good at, and what better time to do than at the beginning of the year. Attached is an explanation, rubric and question and answer form for students to fill out prior to their presentation date.
