Diigo is an answer to prayer for this right-brain, random-abstract, creative-not organized teacher!  I've tried keeping a notebook list of websites I love, bookmarked way too many to keep track of and even made little business cards with hole punches to a binder clip to flip through. Much to no-one's surprise...none of those really helped.  Diigo has me hopeful that I can not only save useful websites but categorize them and search for them later to actually use!!  It even has the option to collect websites to share with your students or co-workers.  There are numerous options to explore.  Diigo
Here's an article to read to illustrate the usefulness-Using Diigo in the Classroom  and a video to help you get started:

Another organizational tool I like is Remind.  It's a safe way to communicate with students and let them know of a test coming up, a special day to dress up for, or a project's due date.  The website takes care of the texting so you don't have to give out your cell number to the students.  iTunes Preview of Remind

Thought Boxes is the last organizational tool I'll focus on tonight...  it's like a web-based to-do list that is a bit more creative.  Thought Boxes article will enlighten you to the benefits of the website.  I'm eager to give this tool a try as it mixes organization with a little bit of creativity.  Sounds like a win-win to me!

I'm continuously amazed at how much technology offers to us if only we take the time to pursue.  It's in the attitude of progress that I've made a promise to myself to be a life-long learner, be a 21st century and use technology as much as possible and meet the students where they best learn.  Continuing to explore what the internet has to offer is the best way to be the life-long learner I want to be.
