A simple grammar revision (elementary/ pre-intermediate levels) that could be used as a test (as I did) or a worksheet for grammar revision. It's fully editable so you can easily adjust it to your needs. In ex.1. students have to complete the conversation by filling in the correct forms of the verb “to BE“ (present simple). In ex.2. they have to replace the bold word(s) with the correct subject pronouns. Ex.3. deals with indefinite articles (choosing between a or an). In ex.4. again students have to write the correct form of the verb to Be (present simple). In ex.5. they have to order and answer some simple personal questions, and finally, in ex.6. they have to complete the table with cardinal and ordinal numbers.
Hope it's useful.
Have a great morning/day/evening!
