Final answer:
The correct conversion of the sentence to indirect speech, keeping in mind the present tense reporting verb 'says', is 'Juffou says that the whole class's work is up to date and you can play outside.'
Step-by-step explanation:
When converting a sentence from direct to indirect speech, you must change the tense of the verbs to reflect the shifting of perspectives. In the sentence provided by the student, "Juffou says: 'The whole class's work is up to date; You can play outside,'" the verbs need to be changed from present to past tense when reporting what Juffou said if the reporting verb is in the past tense. However, since the reporting verb 'says' is in the present tense, the reported clause remains in the present tense as well.
Thus, the correct choice here would be:
Juffou says that the whole class's work is up to date and you can play outside.
