In Skywalkers, homework is given out on a Friday, to be returned by the following Thursday. It will usually consist of Learn Its/Spellings and short Literacy and Numeracy tasks.
Homework is intended to supplement class teaching - it is highly unlikely to be something completely unfamiliar to you! If you are struggling with the homework tasks, your first option is to seek help from someone at home (maybe an older brother or sister, who are often keen to show off their knowledge!)
If this doesn't work, please speak to Mr. Gamage or Miss. Edge in school. We are both here to help!
