What is a Fraction?

Wednesday, September 26th, 2012

A couple of Calgary Math Ed students have announced on LinkedIn that they are starting a Concept Study of Fractions. This is a good idea as the topic is often challenging for students and I suspect that one reason lies in its language. "A fraction is part of a whole" is consistent with the use […]

Transcript looks good except for one unfortunate adjective. It's a pity that the president of a nation founded on the principle of separation of church and state cannot name the state of Israel without identifying its established religion.

Why I do this

Sunday, September 23rd, 2012

In the absence of any readers this may seem pointless but somehow I find it useful to keep links to things I come across and to record some of the thoughts I have about them. The WordPress tool lets me do this and although it might as well be private it feels as if even […]
