In an easy conversational tone, the instructor uses the computer screen as his 'blackboard' and different colors to emphasis his points. As this is an introduction to dividing decimal numbers, this video is for older elementary students. (09:48)

In this video segment from Cyberchase, the CyberSquad must build a rail line to get around the mountain to transport flowers gathered from Thornium Mountain. To do this they must complete decimal addition to figure out how long to make the new rail l...ine. After looking at their sum, the CyberSquad believe that something is not quite right. They realize they did not line up the decimal points when they added the numbers, so they fix their mistake and add up the numbers again. Run time 02:33.[more]
