Are you attending the International Society for Technology in Education (ISTE) conference in Philadelphia this year? There are nearly 600 educational technology companies exhibiting at ISTE and it can be a bit overwhelming to know where to start.

We’ve put together this handy list of the ISTE educational technology companies that are featured on edshelf.com. Edshelf is a fantastic free place for teachers to discover, review and curate edtech.

If you find an innovative and useful edtech product that’s not included here, feel free to send us an email at info@telpmedia.com and we’ll add it to the ISTE tech list.

If you’re attending ISTE, stop by to visit us in the Drawp for School booth #406 and follow us on Twitter @Julia_Brannon @TelpMedia and@DrawpEDU. Be sure to follow the #ISTE2015 hashtag for more ISTE news.
