Arriving for my scheduled
three hour tutoring session this morning I was taken aback to find a learner
not only punctual but also in attendance after an absence of five weeks or so,
and for whom my prepared ninety minute lesson around pentominoes would be a
little light in content; so I prefixed it with some relevant revision on
perimeters and areas of rectangles, followed it up with an introduction to the
simpler tetronimoes, which in turn gave me the bright idea of for once using
his addiction to his mobile phone to my advantage by suggesting he download
Tetris and play it for half an hour to familiarise himself with those five pesky
four-squared shapes before moving on to
the planned lesson on the even peskier twelve five-squared pentominoes.
