First, I'm going to say, for an almost daily supply of smart board resources I think you should look to the left of your screen and follow my blog :) I just started it, and I'm going to do my best to keep you updated with the latest and greatest resources.....
Next, I'm going to introduce you to Kerpoof, which is seriously the coolest thing EVER! For primary grades there is an activity where you can spell a picture, you spell a word and the picture pops up. For upper grades my favorite is the story maker. There are endless backgrounds, people, even little props you can add! I can not wait to use this for one of my creative writing this year.
Below is one of my pages (kinda lame, but I did it super quick.) I dragged the background on there, the troll, and the treasure chest. All can be resized. Like I said, it's the coolest thing EVER :) You can save your story or print it off.
