Usually at the top of the iPad App store, if you don't see it check out All Categories.

At the bottom of the Education tab, click on Education collections to see apps organized by content area.

Great app for helping to organize the classroom. Seems hard if you have lots of ever-changing classroom, but good for those that stick around. Also would be a great way to formatively assess through observations by creating on-the-go assignments with the app.

One of the best! Use with classes for assignments, sharing materials, and discussions. Even if you don't use it with classes you can still connect with communities of teachers that do what you do! Grading is very easy on the iPad as well, great idea for formative assessment.

Purely classroom behavior tracking. Set up different types of behaviors, both positive and negative, and quickly give students + or - for their actions. Students can log-in online as well and customize their 'monster', parents can access reports, and teachers can run detailed reports.

iPhone app, but connects with Classroom Organizer by Booksource website to organize your classroom library. Can scan ISBN numbers for your books, students can go to the website and 'check out' and check in books. Great for classroom libraries!

Can create and edit existing Prezi's, not full featured like the site but getting closer every day. Share Prezi's from here and present them as well.

Create lessons or have your students create lessons that include handwriting, voice, and pictures. Can create multiple slides in a lesson. Best part is integration with their site which allows easy access of the videos for students in your classes/school to view lessons.

Similar to Educreations, a little bit different to work with and share.

Great app for creating presentations on your iPad. Very simple...best part is the ability to add public and private notes that are viewable with the presentation later on.

Create 'interactive' pictures. Choose a picture and add 'hot spots' that show text, links, video, and more. Some features on iPad, more on the website.

Create and set-up rubrics and classes to easily assess. When assessing can use rubric, pictures, notes, and video. Great for performance assessments, student presentations, or just any student work.

Very similar to Easy Assessment but different in sharing and a bit on the organizational side.

Socrative is a great assessment tool if your students have access to any type of devices (personal, phones, computers, etc.). Very easy to create assessments quickly, get fast results to analyze. Favorite thing is the compatibility with literally any device. If they can't get the app they just need an Internet browser.

Great website and platform in general for free blogging with your students. I have some students who use the app to post, I myself love the ability to review and approve student comments quickly. As students write I'm able to walk around the classroom while approving comments.

I check this app...every single day. There are always free apps out there and this is my favorite app for checking that out. Must have!

There are lots of different versions of this but this is my personal favorite. Quickly take pictures of documents (or literally anything), package those pictures together as one file and share it in a multitude of ways. I haven't used a flatbed scanner in years.

I know Google Translate isn't perfect but once upon a time a student who spoke absolutely no English walked into my classroom. Using my iPad her classmates and I managed to help her understand everything going on and even helped her to participate in a group project with no issues whatsoever. That day, Google Translate was my life saver.

More than just Google search, make sure you have the Google app. If for nothing else to try out Google 'goggles' or image search that searches the web for a picture you take.

Skitch by Evernote is a very handy image and document markup too. I love snapping screenshots to send to people, dropping them in Skitch and adding a few notes and arrows to help guide them.

Evernote, the mother of all note taking apps, is just too darn handy. I have it on all my devices and I wish with everything it had been invented when I was writing massive research papers in college. What a great tool to organize all KINDS of not just notes, but attachments, pictures, and voice notes.

At first I thought..what's the point of these QR things?? But they can come in very handy. Put a QR code on sheet you give students that directs them to a website to visit or use, share a cool resource, or point anyone to more information about something. Create a code here that will take you to any link you choose, then send it to yourself to print out. Very fast, very easy.

But you must have something to scan those pesky QR codes with!

Khan is great for short simple explanations on a variety of topics. The app lacks the exercises ability that comes with the full site, but quick access to the videos and transcripts is great.

Check out some of the free courses in iTunesU and if you're feeling daring...you can even set up your own course that others can subscribe to.

Another fun exploration app, visit anywhere in the world...literally. Love the 3D aspects on the iPad and the ability to get additional information on places you're "visiting".

A very cool app to find and create 'how-to' guides. Want to show how to make chocolate chip cookies? Simply take pictures of the steps as you go, drop them all in a guide, add notes, and voila you have a gorgeous guide to share with others. Lots of creation possibilities with this app and lots to explore.
