Hello David! :)

          Thank you so much for making your homework. I would like to say thank you for being an active student in the class. I could see that you always try your best to express your thoughts in a complete sentence. Keep going David. You are on the right track.

             Just a few reminders. Be careful with your spelling. Those words that I colored blue was your misspelled words. You would know if you typed it wrong because the red line will be visible. Also, try to read more of English materials David so that you can use different vocabularies in your sentence.

     See you in the class David and  always remember that teacher is here to help you. :)
