And while I'm a college mathprof and have no first-hand experience with kid discovery inside regularcurricular constraints, I've seen a lot of elementary teachers doing itwith all kinds of classes, and have done more and more of it within my owntime constraints in college classes.Addition of fractions (from a previous message of yours) is a perfectexample.  We don't save any time *telling* kids because they instantlyforget it and have to be taught it over and over again from grade n tograde n+3 (where n is either 4 or 5, depending on the school district).I suspect that lack of using discovery is why we keep repeating the sameidea in different guises instead of acknowledging the unifying idea.  Foran example, consider the distributive law, which in UCMP's Transition Math(which, by the way, I generally like provided you have to use a textbook)is presented in two forms: a(b+c), and a(b-c).  This is ridiculous!  Ifkids were already comfortable with moving blocks around and back and forth,i.e. with inverse operations, you wouldn't need two separate days to dothis.Cheers.        	       	       	====================================        	       	       	Judy Roitman, Mathematics Department        	       	       	Univ. of Kansas, Lawrence, KS 66049        	       	       	roitman@math.ukans.edu        	       	       	=====================================
