explain

Hello!
Is this sentence correct: ‘You should be very attentive when the teacher explains to you the lesson.’ ?
Thank you for your time!

I think it’s correct but I would rewrite it like this: ‘You should be very attentive when the teacher explains the subject of the lesson to you .’[YSaerTTEW443543]
