this photo was shot during an extended on-location family session that we did at the park that involved his sister, mother and father. i just used 22050 because it is common. six patients have been treated for 16 weeks or longer. it is not contagious and can not be spread from person to person. it's all still very new, this is only my second video and i was hand holding it-whoops. each page bar also has the option to delete and copy the page. present the video to the class, use it for math review of facts.
