I would suggest checking out this website:
It is a great website and offers tons of free educational resources and lesson plans for all teachers K-12. The website divides into sections for educators, students, parents, and afterschool activities. What might be of interest for a particular class is the 21st century skills link, which directs you to understanding more fully the role that technology can and will play for the teacher who needs better technology for tomorrow's lesson.
I am posting this other link to a wesbite as well:
This is ISTE: ISTE 100 which stands for the International Society for Technology in Education. Here, you can become a member of their website. They offer professional development opportunities. There is a wealth of links that offer valuable resources for exploring this company further.
