"Yet, it's quite common nowadays to be in a situation where you have to use a section of the PDF file. For example, if you want to grab some images or graphs from an existing PDF and place them into your own PowerPoint presentation, you are unable to do so, as the PDF is not editable. Unless you buy an expensive PDF editing program, you cannot copy and paste images from PDF documents. That is why certain companies have created simple tools that address this particular issue. So, without any further ado, here are the 5 best PDF to JPG converters that are accurate, simple to use and free:"

"Giant Thinkwell's free iPad app Haiku Deck may prove to be the spice rack for your flavorless decks. The idea is straightforward: use one of Haiku Deck's provided two-line templates for your slides, and the app will search Creative Commons-licensed photos to provide a fitting visual complement to your verbiage.

"Imagine if we taught pilots to fly without ever letting them in a cockpit. Or gave them the keys to a commercial airplane without the required hours-or years-of hands on training and practice. Sure, we'd show them plenty of PowerPoint presentations and make them sit through a few seminars on the theory and physics of flight, but then we'd slap on a graduation cap and let them take off into the big blue sky. Not only would it likely be ineffective, it would be borderline criminal. Yet when it comes to professional development for classroom teachers, that's almost exactly what we do. Most professional development opportunities for educators are still lecture style - telling, showing, and explaining how something can be done. And when the 'learning' is finished, we push teachers onto the runway with a cabin full of students and wish them luck. Predictably, many crash and burn."

"Math needs better PR. When it comes to coolness math really should be up there with the new iPad, the latest X-Factor winner and whichever color is fashionable this season. Often people actually think that it's cool to not be able to do math! As part of Maths Insider's mission to make math cool I've pulled the best math quotes from the Twitter stream @Math_Quotes, and used my limited artistic skills to add them to some nice backgrounds (Powerpoint templates in fact!). Enjoy and do share them with your friends and family! Math needs all the PR it can get!"

"appoLearning Collections enable teachers to create, annotate and share lists of hand picked digital resources, including YouTube videos, iOS and Android apps, and websites, around specific subjects, topics or lessons. Collection creators can easily: select from thousands of expert-vetted, standards-aligned resources from appoLearning search and/or add their own resources (including anything that is URL-addressable including videos, apps, websites, assessments, Dropbox links, Google Drive links, Evernote links) and upload their own files (Photos, Lesson Plans, Videos, PowerPoints, PDFs, etc.).  "
