As I am a Google for Education Trainer, I presented a workshop on 'Good Google Tools for Portfolios for the Teaching Standards', a subject that all teachers need to address. There are so many easy ways to get your portfolios together for certification, and appraisal, through which your principal must ensure that you meet the standards.
I am sharing my slides here and also will shortly add a video which will talk you through the slides. Hopefully, you will find some gems here which will suit your purposes. What you actually need for your portfolio is shown in slides 10 - 15. Some examples can be found on how you can do that in later slides along with some of my youtube videos.
