10-2 Activity (Teacher notes)

10-2 Activity (Teacher notes)

This lesson should take 10-15 minutes with discussion solicited from students.

The “10” in a 10-2 activity is the 10 minute lecture/lecturette which is the PPT presentation in this case. At the end of 10 minutes, teachers should pause and ask students to pair with each other and 1) review key points in the lecture and b) come up with any questions or points that need clarification. This is timed for 2 minutes (hence, the “2” in 10-2). Teachers should then field questions, clarify points, etc.
