Thanks, Allan. It looks really interesting.
difficult child 3 signed up for Mathletics, a low-cost version of some of those very expensive computer tutor software packages. It cost us A$90 a year. It helps him to do some drill. I'm still trying to organise him on some sort of timetable, to do some every day. But he enjoys it and it is set to his current grade level. We can change it if we need to.
This website looks different again, like bits and pieces here and there. I'll show difficult child 3 in the morning (it's currently close to midnight here).
