In case you are one of the few that don't know what I'm talking about, pinterest is a visual bookmarking system that lets you pin a picture link to a bulletin board. Think of it as the 21st century answer to the "wedding scrapbook" - you know, when you were planning your wedding and you would cut out all the pictures of the things you liked and make them into a book? You didn't do that??? That's okay, I didn't either... But I was always envious of those people with mad scrapbooking skills to organize their memories :)
Anyway, back to pinterest... As you are browing the web (in my case today, blog posts that I had starred or google images), if there is a photo/graphic that you want to remember, you can pin it to a board. For a visual person like me, I can look back at my "Algebra" board and think "Oh yeah! Love that teaching idea!" without having to go read the entire post. Of course, if you click on the picture, you can go read the post if you need some more prompting...
My Algebra board so far...
I have boards for the courses I teach, foldables, classroom organization, general teaching ideas, etc.
One downside I have found is that a lot of blog posts (especially older ones) have great ideas but don't have pictures included. I am going to try to do a better job of documenting my posts with pictures to make it easier for people to pin :)
Try it out! It's so easy and very addictive :)
