Why not ask an adult or a sibling to test you on the 3 words you wrote on the sticky notes this week?
I know you don't have your spelling books at home but you could do your spelling test in your planner instead, under today's date.
You can then ask someone to check and mark them. Remember it's a neat tick for correct answers or a neat dot for incorrect answers.
Any spellings you get incorrect can be carried forward to next week's test.
