Ever wonder what a leap year really is? I am teaching Social Studies 9 this year and our first unit is called Time. We learn about the Julian and Gregorian calendar, along with solstice and equinox, we dive into the world of time and how it came to be. The one thing that really interested the students though was the concept of leap year. I explained it, we read about it, we discussed it but here is a great learning tool....a youtube video that explains the concept really well. Simple language, use of drawings to help reinforce, and a fun approach equals a video of great instructional quality. I showed this to all my grade 9-12's today and I was actually a bit surprised by those who didn't really know about it fully or understand it before the video. Cheers to day 366 and Happy Leap Year Day!
