the noun form of the word 'homework' refers to tasks or assignments given to students by their teachers to be completed at home. These assignments are typically meant to supplement classroom learning with additional practice or memorization and are an integral part of any schooling system.
1. My granddaughter has so much homework to do this week that she's barely been able to watch any TV.
2. I have to study for tests and do all of my homework if I want to pass the class.
3. Every day after school, I spend a few hours doing homework before I even think of going outside.
because 'homework' can refer to a variety of assignments, it is important to be specific when speaking of it. For example, you could say 'I'm almost done with my math homework assignment,' to clarify that you mean the one related to math instead of the English composition homework.
