I have done a couple video blogs before and they are challenging for me. I am not very comfortable filming myself! This is a short video blog on subitizing and how it fits in with operational development. I try my best to make them easy to understand as sometimes math edu-babble can overwhelm people when they are first learning. Its another reason why I thought seeing it as a video may help. There may be mistakes, still I think I have caught the essence of why subitizing is so important. There are four parts to the videos. I also try to make the connection to purposeful practice. Hope you enjoy!
