    In my classroom the use of technology and my comfort level stems from, well I have children myself. Seeing them grow up in a society where technology is there. Realizing, this is where my kids are and this is the tool that they have and I need to jump on board with them and help lead the way. Society has her space here right so after she shares you're gonna give her feedback. We're a K to 12 independent school using the Smart Learning Suite. It's pretty amazing. Every teacher uses it in different ways.
