I spontaneously came up with a great way to practice Past Simple with a group of beginners.I already had a board game that I used to practice adverbs of frequency. The fields on the board have different verbs in the infinitive form, so students have to say the Past Simple form of the verb they land on. It was fun and very repetitive, which makes for great practice of regular and irregular verbs in Past Simple.
