Teachhub.com is an excellent resource that I have recently found. On this website, teachers can find numerous lesson plan ideas for all grade levels in various subject areas such as Language Arts, Science, Social Studies and Math. This website also contains links to hot topic articles and 5 different teaching blogs along with contest opportunities for students and classrooms. There is even a tab to find various professional development sessions in your area.
I found this website to very user friendly. It is easy to navigate with the different tabs and pages included. I also used the search engine to find numerous links to websites and articles for specific concepts/ issues I wanted to teach or address in my classroom. There is currently a link under the Hot Topics tab for the best 12 apps for students use on an Ipad. I definitely reccomend checking it out if you have access to ipads in your school or classroom!
Explore this great resource if you get a chance. I'm sure you will find it helpful and very worthy of your time!
