The video begins with a health reminder about handwashing to prevent coronavirus. It then introduces lesson 12.7, focusing on measuring lengths using metric units like inches, feet, yards, centimeters, and meters. The lesson reviews these units and their tools, followed by a practical example of measuring a desk. A hands-on activity involves measuring a pencil in different units. The video concludes with an assessment and homework instructions.
