The first activity presents Hallowe'en-related vocabulary items in scrambled form. Pupils unscramble the letters to write words pertaining to Hallowe'en.
In the second activity, pupils unscramble groups of words to write sentences talking about Hallowe'en.
These activities can be done in pairs or individually. A "beat the clock" format can be conducted in which the teacher times the class and the first three pairs of pupils to finish the activity receives bonus points, prizes, or some other sort of motivational items.
