I don't sense any "useless" idea in that sentence.
The sentence means we didn't go to school yesterday because we weren't required to. Maybe it was a holiday, or maybe the snow was so deep no one could get through! Or something else that meant there wasn't any school yesterday.
We didn't have to go to school yesterday.
(What is the meaning of the sentence?
Is it #1 or #2?
1. We didn't go to school yesterday because it was useless.
.
2. We went to school yesterday, but it was useless. )
