Daily lesson planning, anyone?

OCTOBER is the month when public school students go into a week-long break ending the first semester of the school year. The break also allows their teachers to attend training arranged by their respective division or district offices.
I was reminded of this after my wife, who teaches geometry at Camarines Sur National High School, was extra-busy last week – as Math club president, she had to oversee their departmental in-service training and aside from that prepare something to share to fellow math teachers.
