Rex, thanks so much for reminding us of these.
There's a very helpful essay about making this type of question, by Peter Sullivan. It's in his book with David Clarke, "Improving the Quality of Learning by Asking Good Questions." In P. Sullivan and D. Clarke. Communication in the Classroom: The Importance of Good Questioning. Geelong, Victoria, Australia: Deakin University Press. 1991.
For example: Two numbers sum to eighteen. What might they be? Janie had eight cats. Some were striped, the others were black. How many of each might there be?
And there are many examples of this kind of question in the TERC curriculum for elementary grades (Investigations in number, data and space) published by Dale Seymour.
They are interesting questions that allow for a whole different discussion than their counterparts do. For example, in a second grade class that investigated numbers that would sum to twelve, the discussion revolved around one child's observation that you could include 1/2 and 11 1/2. Others submitted their ideas (other half-number pairs) and then someone suggested fourths. Well! There was quite a number of number pairs they ended up with, and the teacher was ecstatic.
Thanks again, Rex.
