[blindkid] [Pibe-division] Questions about rulers and perpetual calendars

Robert and everyone,

These are both good suggestions, but I think it is important that in a classroom setting that the measuring take place in a manner similar to the rest of the 
class.  To me, learning to measure with a ruler that only has one-eighth division is less of a problem than using a ruler that works differently than what the 
rest of the class uses.  There are advantages to knowing what the other kids are using.  I guess the click-rule is pretty close.  Clearly, for serious measuring, 
both of these would be a better option as is the talking tape measure that I usually use.

Best regards,

Steve Jacobson
