Searchable Lesson PlansI discovered that there are searchable lesson plans for a variety of topics using a variety of tools which you can search here.
Google Educator CertificationIf you are keen to learn more, Google have recently updated their educator training site to allow you to take a series of online exams to gain certification of your proficiency with the Google Apps for Education tools and their use in the classroom. Each exam is supported by a large amount of training material including written explanations, instructional videos and links to support materials.
Google+ CommunitiesGoogle+ is Google's social network and within it are a large number of communities dedicated to the use of Google Apps for Education in the classroom. If you have a Google account (personal or organisation) then you can activate your Google+ plus account and start sharing and learning. Once signed up I strongly suggest you use it purely for professional development and treat your profile and those you connect with in the same way. All social networks work more effectively for you if you have a purpose for using them.
Here are some communities to consider joining.
Google Apps for Education - Educators ask questions and share tips
Google Apps in Education - As above but slightly different name
You can create communities yourself and some are being used very effectively for education, creating an environment for sharing with students (over 13 years old, as Google does not allow people under this age to create an account).
Look out for a new string of "Google Educator Group" communities for regions around the UK and the world. I will be helping to administer the Google Educator Group for South East UK so if you are using Google tools and teach in the region please join the community to get tips, dates of events and share ideas on using Google tools for learning.
