I found a resource website for Smartboard lessons at "Tequipment's Educator Resource Center". A user has to create an account, but it's free and I like what I see so far. Lessons are broken down by subject as well as Elementary, Middle, and High. Not only do I find some great basics to build on for lessons, I'm getting some great ideas when I build my own.

I still use my Smartboard regularly, but struggle at times maintaining engagement in whole group situations. We often do "talk with your partner/group" about the answer/concept and then I draw stick names to complete it on the smartboard. However, this seems to be where I start to lose some students as some students still struggle at times with writing/drawing on the board - either with pen or finger. Some even still struggle dragging objects with their finger. I feel my lessons begin to drag! I try to help either by laptop or at the Smartboard with them, but am left wondering what else I can do. I would LOVE suggestions!
