Spelling and Vocabulary Tasks/Spelling & Vocab Collection
This is fairly straight forward. Set a pre-test using a collection of words from each group. Collate the marks and allocate students into appropriate Word Groups. Give a print-out of sheets to students and run a test each week. While you run through each group, those students not involved can either be revising or learning their words if their test is next. An easy way to differentiate. See the additional instructions on each sheet for promotion-prospects and also for vocabulary tasks too.
