There are so many places on the web to find information!  Few of my favorites are Facebook, Pinterest and Teachers Pay Teachers.

For the SLP on a budget teachers pay teachers has many free and cheap materials that you can print and use in Therapy. and yes Many of these materials are developed by other SLPs.

many SLPs now have Facebook pages where they post their blogs, teacher pay teacher materials and reviews of apps or materials. And many times they will also have rafflecopter chances to win materials!!!!

many SLPs also post materials and activity ideas on Pinterest. Between these three sites alone a person can get lost for hours! there are many more sites out there. These are just a few to begin with.
