Grammar Tool: British Council

    British Council (https://learnenglish.britishcouncil.org/grammar) is an online grammar-learning website that provides language learners to practice their English grammar with clear grammar explanations while allowing them to test their understanding with its exercises after each grammar topic. It has lessons regarding all levels and the learners can easily find out which level they are in by taking a quick grammar test. 

                                                                                                                                                                              

    With interactive exercises under each subject, it enables students to actively participate in the class by discussing the answers with each other in the classroom environment, so the teacher can benefit from these exercises as, for example, an end-of-unit assessment test. The website also has detailed grammar lessons in text form including plenty of examples.
