As part of my instructional technology responsibilities, I try to help teachers use whatever resources they have available in their lessons. Teachers have access to computers, the Internet, some interactive whiteboards and numerous applications so they can create new activities and assessments and/or use SMART or ActivInspire lessons that coorelate with the desired standard.
I have really enjoyed finding resources and helping the teachers learn where to look for different types of activities to compliment the standard they are teaching. The Learning Village resource has been our one-stop shopping experience for finding everything from a grade-level pacing guide, instructional tool such as Thinkfinity, links to subject-area wikis, technology integration activities, and much more. Learn 360 and netTrekker are two resources that correlate the videos, images, etc. to a specific standard. This makes it very easy to develop an activity or assessment. Some of my favorite reading/language arts activities come from ReadWriteThink and Wonderopolis.
Our elementary group has pulled together many of the Elementary Resources into Livebinders by grade level. They are on our DIT wiki and available to the teachers. We update the binders and wiki pages as we find resources for the core subject areas.
If you need an idea for an activity or are looking for a website to reinforce an objective you've taught, why not check out one of the above online resources. I highly recommend any (really all) of them to help make learning fun.
