Unjumble words task (see)
The task consists in reordering the words on a line by moving them with the mouse.
By forcing linefeeds, one can a get a set of standalone lines whose words are to be reordered.
For a full-fledged text, the task may be formidable. The activity should come after preparatory stages, once the learners are reasonably familiar with the text. In-depth comprehension is a prerequisite.
