P.A.T. and grammar puzzles

I've talked before about how much I struggle with my second year students. They are just sooo hard some days! I love their personalities and they are so funny, but it causes a real classroom management problem most days. Today, they made me so proud! Lately, I've been having students try and write the answers to the day's song/grammar puzzles on the board for minutes for P.A.T. Today it hit me how awesome they are doing on this. They are really focusing on trying to "catch" others' mistakes and actually trying to solve the puzzle on their own before the answer is written on the board. Today, one of the puzzles was "I will take her place." We have not worked with the futur simple, but I have thrown a couple of examples in on our grammar puzzles because it appears so frequently in song lyrics. I had a student today write "Je vais prend sa place." Another student piped up and said, "I think there is supposed to be an -re at the end of prendre." I was blown away. First, that a student would find a work-around for the phrase instead of inventing a word for "will" and second, that a student would pick up on the missing -re! It might be commonplace in others' classrooms, but I was proud of these kids today. Thank goodness! I was about to tear my hair out!
