I took advantage of a sunny to day to present the past tense in a slightly different way.
By putting the text on a bench we created the perfect way to advantage of the spring sunshine. The students took it in turns to run outside and remember bits of the text to dictate to their partners.
When they had finished we wrote up and corrected a class version of this running dictation.
Then I gave them all a pen to underline the verbs,
Voilà! The past tense!
