Sorry, it can't be done...
(There used to be a post here explaining how this could be done, but it's no longer possible. Instead, this post now explains how you can share a text with your students without uploading it to textivate, provided you have a Premium or Group subscription and your students are logged in using the student log-in. See below...)
Most of what you can do with textivate requires you to pay for a subscription:You need at least a basic subscription to textivate if you want to upload a resource to textivate so that you can access it on another device. A basic subscription only allows you to save a resource as a private resource, so it can only be accessed by the person who created it, when they are logged in to textivate, via the "My resources" section of the Search / browse page.
You need a premium or group subscription if you want to upload a resource to textivate and share it via...
1) ... a url linking to the home page. e.g. http://www.textivate.com/l2gjn1
2) ... a url linking to the menu page. e.g. http://www.textivate.com/menu-l2gjn1
3) ... a url linking to a particular activity. e.g. http://www.textivate.com/m_click12-l2gjn1
4) ... an embedded activity. e.g.
You can also share a resource with your students without uploading it to textivate, provided you have a Premium or Group subscription and your students are logged in using the student log-in
OK, so it isn't quite as neat as the examples above, but it can be done like this:
When you share a resource on textivate, all you are sharing is a piece of text. (If you think about it, it makes sense - when you create a resource on textivate, all you are doing is placing text into a text box.) You can share a piece of text in lots of different ways: a word doc, a google doc, a txt file, a piece of text on a webpage, wiki, blog etc. There are lots of different ways.
So, imagine you've got a text that you want to share with you're students (I'm going to use the same text as the one used in the examples above), why not just do this?:
Instructions:
1) Copy this text:
Je [#]vais à l'école tous les jours avec Pierre. Nous [#]allons à l'école en bus.
Mon copain s'appelle Georges. Il [#]va à l'école avec son frère. Ils [#]vont à l'école en voiture.
Ma copine s'appelle Sophie. Elle [#]va à l'école [#]avec sa soeur. Elles [#]vont à l'école à pied.
Et toi? Tu [#]vas à l'école avec Marie, n'est-ce pas? Vous [#]allez à l'école comment?

2) Go to http://www.textivate.com
3) Students log-in using the student log-in provided (along with your Premium / Group subscription)
4) Delete the default text (click on the blank paper icon).
5) Paste in the text.
6) Click "textivate now"
As I said, it's not as elegant as linking directly or embedding.
But it can be done.
And once students have done it a few times, they'll become familiar with the process, and all you'll need to say is "Textivate this text:..."
A subscription to textivate won't break the bank. If your school bought a 1 year premium subscription, it would cost them about the same as one hour of your teacher salary. A group subscription has 10 separate log-ins and costs about the same as 3 premium subscriptions.
