Present Perfect Tense 

9th Graders

To make the positive present perfect tense, use:

• 'have' / 'has' + the past participle
• Make the past participle by adding 'ed' to regular verbs (for example, 'play' becomes 'played')
• There are a few verbs that change their spelling when you add 'ed' (for example, 'study' becomes 'studied')
• We also have some completely irregular verbs
