"My children do not like going to school."
Translation:Мои дети не любят ходить в школу.
"Мои дети не хотят идти в школу" would make sense - my children don't want to go to school (right now). But for an habitual activity you use an imperfective verb, so ходить.
идти is also imperfective. You need an imperfective and multi-directional verb (at least that's the terminology used by this course).
