These were not homework problems, but DS caught these teacher mistakes last year, while in 4th grade:

* Teaching science: The sun doesn't move or rotate.
* Teaching math:
=> Teacher: A circle is made up of a lot of points
=> DS: Isn't it made up of an infinite number of points?
=> Teacher: It depends how big the circle is
=> DS: Stood there with his mouth open not knowing what to say
