Sign in to track this

What mastery looks like

  • Write sentences using commas with yes and no at the beginning such as 'Yes, I understand'
  • Punctuate tag questions correctly such as 'It's cold today, isn't it?'
  • Use commas to set off names in direct address such as 'Sarah, please pass the salt'

Check your understanding

When Commas with yes, no, and names writes dialogue or a letter and addresses someone by name — like "Yes, Mum, I did tidy my room" — do they use commas correctly around the name and around words like "yes" or "no"?
