Revision and activation of structure used to/ didn't use to for intermediate ESOL/ EFL /EAL learner

This is a dynamic 60-90 min lesson for intermediate ESOL/EFL/EAL learners aimed to revise and activate the structure USED TO/DIDN’T USE TO.
It starts with the grammar activity, where learners work in pairs or small groups and correct mistakes in given sentences.
Make it into a competition between groups and give a point or two for each correct answer. Invite students explain the rule and remind them when to use the expression. The exercise also reminds students that we use the structure to indicate past habits and the equivalent for present habit is usually.
Next activity is a mingling activity,where students walk around the class and ask each other questions to reinforce the use of the structure.
To further activate the use of structure, learners write a piece on the topic ‘An accident in your childhood’.
The plenary is a WordWall activity to check what learners remember from the session.
