Thanks to Emily for finding a typo. The corrected version was uploaded on Jan 31. I am looking forward to using it with my Year 9’s today, For many it will be the first time they use their new calculator.

Worked really smoothly. In 20 minutes they were reasonably comfortable, still need time to develop familiarity and I liked this comment “It is pretty much like the other calculator except it does more and you need to find stuff in the menus (keyboard)”. A positive start!
