Arrange the digits
Download a jqz file with 8 questions about rearranging digits to make the largest and smallest numbers. You can also save a Web page with the questions about rearranging digits and use that with students.
As usual, I have set the HotPotatoes options to remove all the buttons (the quizzes open in new windows in Moodle), and I have set the options to shuffle the question order and to shuffle the order of the answers each time the Web page is loaded. As each 20 Minute quiz is short and deals with a single topic, this seems to make sense to me.
