Due to the covid-19 school closures, I bought this on Amazon. This is SO easy to use and it is SO affordable compared to an ELMO. I use a Chromebook and this works out great. I can record something or snap a picture with the ability to immediately upload it to my google classroom. I am brand new to google classrooms so this feature is a hit. I wish I could get another one; my school does not have ANY doc cams in any other their classrooms. I teach in a special needs nonprofit charter school so this is perfect for using manipulatives in math, writing lessons, sight words, games and more when my whole class cannot see what I am doing on my work space. I can use this with an interactive white board or projector.
