From ictgames.com. Randomly type in all the words you need for a sentence substitution activity (even though the screen asks for a sentence). When you press the blue button it provides you with each word on a separate card. You can click and then pull these onto the runway to read as a sentence. Press the 'again' button to return the words to their starting places and make a different sentence. Useful for the 'apply' part of the lesson as a tool for the sentence substitution activity, but using your own sentences.
