I attach the statutory spellings for Year 5/6. We have already learnt some of these but it won't hurt to revise them. Maybe take 10 a week and learn them. You could even download the spelling app (Squeebles spelling) to test yourself on there.
Or use https://www.superteacherworksheets.com/generator-word-search.html to enter your spellings and print off a wordsearch with the spellings in them.
There are some supporting activities onhttps://www.twinkl.co.uk/resource/t2-e-41719-year-5-and-6-statutory-spelling-words-activity-mat-bumper-pack
