Suggestions

So I’m wondering if we are supposed to even be buying supplies for our classes. Last year, there was a teacher who had multiple types of conversation cards and we used them in stations. This year, I feel like the teachers either don’t have them or don’t simply use them (they don’t do station-type activities). I feel it’s unfair for assistants to buy things for classes as we are not the main teacher and we aren’t making teacher salaries/receiving benefits.

What is something I could do (other than other different speaking activities I have planned) without leading the classroom and giving the teachers a free period?

Thanks in advance.
