The idea is to use recycling
paper to print calendars on.

Print one for each class and put it up on the wall.
The teacher (or a student) can write the homework
each day.

When he made us choose our homework, i feel i didn't do
enough.
I liked how could work at our own pace but I need to work faster
if I want to achieve better results.
I liked how we could chose to do what subjects we did and did
not understand.
I really liked that we could choose what to do and then move on
if we know the rest.

• One of my students in Year 11 Extension 1 Mathematics was
scheduled to have an operation on his knee and came up with
a brilliant plan to not fall behind. The course goes very quickly
and missing any lesson can be difficult – we were going to
cover Superannuation using a GP.
• He organised with a friend to skype in from home to watch the
lesson as we progressed.
• For part of the lesson, he was sitting on a table in front of the
projector screen (well… the laptop he was skyped into).
• For the rest of the lesson, he sat in his usual seat.
• I wonder if UStream would have been an easier alternative –
although it would not have allowed him to put up his hand
and ask any questions.
