HP Prime vs TI-84 Plus CE for Jr. High and High School

[sasa]

I understand your concern completely.

However, from my point of view, all is clear: if school approve in written form what models of calculators are suitable, that automatically means that all teachers are obligated to be familiar with.

Of course, as we both wrote, teachers are not quite flexible in general, then only the best is that kids asks their teachers what models they prefer in order to be able to gives appropriate help.

All the best in final decision which would be in the best interest for kids.
