Here are a few videos that I created last school year while teaching insertion sorting. The worksheet is from Barbara Ericson, and the tiles idea is not mine. :)
The first video shows a trace through the selection sort algorithm. The worksheet we are using is attached. The 2nd video shows us working through the algorithm using tiles. There is also a worksheet attached to assist in tracking the number of comparisons and accesses to the array.
The sound is not always the best, but I think it is good enough for you to understand what we are doing throughout. Enjoy.
