Dear [Teacher's name],

I am writing about [activity] on [date]. In our family, [brief relevant explanation], which may affect how [Child's name] participates in [specific part]. Could you explain what the activity involves so we can discuss an appropriate arrangement? [Child] would like to stay involved with classmates where possible. One option we would welcome discussing is [suggestion], but we are open to other practical ideas that fit the class arrangements.
