I tweeted a few weeks ago, mentioning my frustration that a well known site on which you can save your favorite images had become nothing more than a re-direct to a site on which teachers sell their work. A number of other teachers jumped into the conversation, offering up the websites on which their own work could be downloaded for free. Many items are editable. All that is asked is that you follow their Creative Commons or other copyright requests.
On the sites below, you won’t find un-editable but cute worksheets that can be easily used as filler. You won’t find un-editable cut-and-paste scrapbooking-type activities that usually generate an attractive product with little likelihood of students engaging in any depth. You WILL find the best work of accomplished, practicing classroom teachers who continually update their lessons.
