Once upon a time, I was annoyed like pretty much everybody by the ads around the webpages. For once, something called my attention AND it was education.com
You can sign up with a normal username and passsword or using your facebook account like other webpages.
With your FREE account you can download 10 worksheets (totally worthy if you manage well your resources). If you want unlimited access to download at leasure, well you have to pay.
I have used it to make the bulletin boards, extra activities with the sounds, holiday activities and so on.
